Can try to trouble shoot on your own.
Probably wiring between battery and CDI got a problem.

Have you tried to find the problem part of the wire on your own?

I can't open the cover to check the battery and wire etc. Cos no tools.

I dun noe wat to do now.imagine i have to push start to start from point a to point b. Push start again from point b to point c. Along the way, signal blinking very fast yet weakly. No horn also. After I stop, tried to start. But its totally dead. No cranking sound at all. It's as though, the switch is not turned in.

Can u help and advise?

CSV · May 15, 2011

probably your rectifier is fried.

brand new battery gets drained very fast right?

if so, probably is la.

ah chong has spares for it. think around 180?

Magnetic coil and battery ok according to them. Went to planet less than a month ago. He told me is the battery spoil, which I reluctantly changed. But problem back again.

jeffrey83 · May 15, 2011

If really CDI problem, how long will it take to repair? Do I have to leave it at the shop?

CSV · May 16, 2011

would be rather fast i think. plus minus 2-3 hours at worst.

jeffrey83 · May 16, 2011

Thanks for help.

Went down to planet. Issuse is the "Starter Relay". Total damage is $30, second hand. So far, I tried on and off the engine, and it's ok. Can start. Hopefully, this is the cause of problem after quite some time.

Also, mine is FV xX2 G. Coe ending next year 2012 June. Am completating to renew or nt. According to others, they say not worth it to do so. It's very high, as we all know. On the other hand, do not know what bike to buy. Super 4 very high in value. I quite big size, which 2b suits other than ta200?

Silent Hunter · May 16, 2011

My DR also had this problem before when I went for a Malaysia trip, you can actually hotwire it, but be warned, lots of sparks! Hahaha!

Got a brand new relay for $65 (or was it $85) for it when I came back.

Hmmmm.... but when my relay was fried, my horn and lights were working just fine.

Sorry I couldn't diagnose it better for you, but I am glad you got it fixed.

just renew the coe unless you get another bike... and when you change your mind in the future, you can just cancel the remainder of the coe and get your money back

Phantom TA200/TA150 List of Problems and Solution

Problem 1: Exhaust emitting white smoke.

Reason: Engine oil is leaking into your chamber.

Solution: Pistol rings needs to be changed. Go to a bike workshop.

Reason: Your bike has a 2 stroke engine(ta150).

Solution: Its normal.

Problem 2: Engine stalls in heavy rain and unable / weak to start.

Reason: Spark plug could be getting wet by the rain causing it not not function

Solution: Remove, dry the spark plug and put it back properly. Go get the plug cap replaced.

Reason: Air fuel mixture may be too rich or lean.

Solution: Tune your carb to a leaner setting (turn screw anti-clockwise by 1/4).

Reason: Air leakages.

Solution: Change some of the rubber parts in tank.

Reason: Air filter clogged.

Solution : Get your air filter changed.

Problem 3: Flat / Punctured Tyres

Solution: Try to inflate tyre with portable pump / bicycle pump then go bike or tyre shop. DO NOT ride on flat tyres as they may damage your tyre or wheel.

Solution: Use tyre repair kit, plug and pump = good to go. Kit can be bought at LAB.

Problem 4: Cannot / Hard to start bike

Reason: Battery may be weak (confirmed by a tick sound from the right side cover under the seat).

Solution: Push Start(Clutch in after running with bike, release, give a quick throttle and clutch in) and go get battery replaced or ride to charge(if still can be charged).

Reason: Fuse may be blown.

Solution: Check Fuse. Fuse is located on right side of bike. Remove chrome cover under the seat and see. Look out for the centre of the fuse if its broken then FUSED lor. Change new one.

Reason: Bike is in gear, kill switch is on, no petrol.

Solution: Obvious.

Reason: Rectifier issue (despite new battery, bike soon becomes hard to start again)

Solution: Get mechanic to check with a voltage meter. Ah chong has one.

Reason: Petrol topped up too full - Don't laugh.

Solution: The petrol tank is not meant to be filled to the brim. Leave some space for air.

Reason: Water in petrol

Solution: Check that fuel cap is secure and no leaks

++ Reason: If everything is working fine CDI might be spoilt

Solution: Tow to shop and change..2nd hand one will cause app $100 1st hand $200+

Others:

- Check ignition coil for sparks.

- Check magneto coil.

Problem 5: Cant go more den 80 km/h

Reason: You are not in the 6th gear

Solution: Down 1 time 1st gear. up 5 times to sixth gear

Reason: If confirm no 6th gear, gear box may be in bad shape

Solution: Go to a reputable workshop for a checkup, may need to over haul.

Reason: Insufficient Engine Oil (Very bad)

Solution: Check with dipstick as according to manual. Buy Engine Oil from petrol kiosk and top up.

Reason: Clutch may have been worn off (Engine reving very high but no power to go any faster)

Solution: Bike shop chance clutch.

Reason: Air fuel mixture too rich (Crazy vibrations at higher revs making it too uncomfortable)

Solution: Tune air fuel mixture leaner (Turn screw anti-clockwise 1/2 - 1 round)

Reason: Sprocket may be worn off

Solution: Change sprocket and chain.

Problem 6: Weird sound on my bike

Reason: Might be battery low. (Ticking sound on right side when start button depressed)

Solution: Push start, change battery

Reason: If sound is on gearbox side, chain may be too slack

Solution: Check your chain tension 1st. Should have about 2 to 3cm slack, tested at the center of the bottom span of the chain. Anything more, get it tightened. Also, lubricate your chain.

Problem 7: - Exhaust Header got holes. Can repair?

Reason: Got one specific hole which is ok.

Solution: If unsure, post some pictures.

Problem 8: - Engine oil Dip stick broken (Broken part might be in engine)

Solution:

Reason: Wheel bearings spoilt.

Solution: Bike shop, get it changed.

Reason: Wheel alignment might have problem.

Solution: Bike shop, get it fixed.

Problem 12: Speedo is not working

Reason: The cable, or the gear at the end of the cable is spoilt or loose.

Solution: If loose, plug it back or tighten. Else needs replacement, go bike shop.

Reason: Speedo spoilt.

Solution: Bike shop.

Problem 13: My exhaust gives have a loud bang regularly. (Backfire)

Reason: Air fuel mixture too rich or too lean.

Solution: Retune the carb. (check problem 24)

Problem 14: I lost my bike Key!!! What to do??

Solution: Go find the key smith.

Solution: If want to change ignition, look for Ah Chong (Planet) or scrapyard.

Problem 15: Bike pickup super slow. Even slower than small cc cars.

Reason: Clutch is worn

Solution: Change your clutch plates.

Problem 16: Damaged Exhaust: Header got hole / Muffler loose or dropping.

Solution: Header got hole can weld it up.

Solution: Muffler dropping can cut open the pipe and take it out but pipe will sound louder.

Solution: Alternatively can change the whole system, pipe + header, about 300+-.

Problem 17: Hard to kick the gears

Reason: Clutch is worn

Solution: Change or top up EO.

Solution: Change clutch plate.

Reason: Your clutch cable is breaking.

Solution: Replace your clutch cable

Problem 18: When cold start, bike got "tick tick" sound

Reason: cam chain tensioner spoilt.

Solution: Change the cam chain tensioner.

Solution: If its rattling sound instead of "tick tick" sound, bring bike to mechanic.

Problem 19: Bike wobble for no apparent reason.

Reason: Might have problem with wheel bearings or tyre pressure.

Solution: Check that the tyre pressure is correct.

Solution: If tyre pressure is correct, most probably is the bearing spoilt.

Solution:Change new bearings.

Problem 20: In Vehicle Unit (IU) Spoilt.

Reason: There is a whole lot of reason, old, water seep in, etc etc.

Solution: But a second hand IU but need to transfer name.

Solution: Buy a new IU at $155.80 w GST.

Solution: Don't go into carparks or go through ERP.

Problem 21: Weak Battery.

Reason: Battery old. Cannot charge or hold properly. etc etc

Solution: Recharge the battery (Wet), Dry ones cannot be recharged?.

Solution: Most people change batteries instead of recharging.

Solution: If leaving bike alone for a long time, disconnect the battery to prevent further unnecessary drainage.

Problem 22: Need to step real hard for brake lights to light up.

Reason: There is a knob for adjustment, it might be loose

Solution: There is a black screw lookalike plastic knob( near the spring) located somewhere near the rear brake pedal. u can play around with the knob by turning to adjust the sensitivity of your rear brake when you apply brake.

Problem 23: IU Spoilt.

Reason: No reason in particular. If its spoilt, its spoilt.

Solution: Inspect at Vicom. Replace a new one if under warranty. If not, have to buy a new one at about $155 (Slim).

Problem 24: Backfire tooooo frequent. Like 3-5 times a day. Or when u stop normally, not even sudden brake.

Reason: Gasket at exhaust head leaking air. Or #2, Exhaust has holes

Solution: Replace gasket. Or #2, send it to Planet Motor (ahchong) to weld the holes, or get a second-hand exhaust or get one cheaper exhaust at LAB (must make order)

25: After turning off my engine there is a tick tick tick sound some where.

Reason: Exhast pipe is cooling down. Hot it expands so cold it turns back.

Solution: Do DIY exhaust wrap. Reduced backpressure = faster heat evacuation, leading to high speed silent running and silent cooldown after engine off. (Kalyan)

Problem 26: Cannot find neutral gear!

Solution: Gear oil not suitable, change different grade of gear oil (see gearoil thread for details)

Solution: Gear box dying.

Solution: Engine is overheated. (Running too lean/ Not enough engine oil.)

Solution: Clutch freeplay not enough

Solution: Remove, dry the spark plug and put it back properly. Go get the plug cap replaced.

Reason: Air fuel mixture may be too rich or lean.

Solution: Tune your carb to a leaner setting (turn screw anti-clockwise by 1/4).

Turning the screw clockwise to enrich the mixture. (once again, tune in 1/4 or 1/2 turns of the air correction screw, located on the LEFT side of the carb)

Bike tends to rev rapidly but have poor acceleration if lean, and if too rich, will have "spongy" / slow throttle response at high speeds.

If in need of advise / demonstration sms pandora's kitten at 93270801 (advice/demo given is FOC)

Reason: Air leakages.

Solution: Change some of the rubber parts in tank.

Reason: Air filter clogged.

Solution : Get your air filter changed. You are advised to inspect the air filter every 4000 or so kms and change it at 10k (Honda warranty service manual)

Problem 3: Flat / Punctured Tyres

Solution: Try to inflate tyre with portable pump / bicycle pump then go bike or tyre shop. DO NOT ride on flat tyres as they may damage your tyre or wheel.

Solution: Use tyre repair kit, plug and pump = good to go. Kit can be bought at LAB.

Solution 2: Buy a can of fix a flat from Carrefour or petrol stations, put it in your box.

Problem 4: Cannot / Hard to start bike

Reason: Battery may be weak (confirmed by a tick sound from the right side cover under the seat).

Solution: Push Start(Clutch in after running with bike, release, give a quick throttle and clutch in) and go get battery replaced or ride to charge(if still can be charged).

You are advised to use third gear to push start (due to Phantom's short gearing) or even fourth on very slippery driveways (such as on some landed properties)

Reason: Fuse may be blown.

Solution: Check Fuse. Fuse is located on right side of bike. Remove chrome cover under the seat and see. Look out for the centre of the fuse if its broken then FUSED lor. Change new one.

Reason: Bike is in gear, kill switch is on, no petrol.

Solution: Obvious.

Reason: Rectifier issue (despite new battery, bike soon becomes hard to start again)

- Check magneto coil.

Problem 5: Cant go more den 80 km/h

Reason: You are not in the 6th gear

Solution: Down 1 time 1st gear. up 5 times to sixth gear

Solution: If you have very poor acceleration when throttle is opened, you are running lean. Enrich mixture by 1/2 to 1 turn of the air correction screw.

Reason: If confirm no 6th gear, gear box may be in bad shape

Solution: Go to a reputable workshop for a checkup, may need to over haul.

Reason: Insufficient Engine Oil (Very bad)

Solution: Check with dipstick as according to manual. Buy Engine Oil from petrol kiosk and top up.

Solution: Check your chain tension 1st. Should have about 2 to 3cm slack, tested at the center of the bottom span of the chain. Anything more, get it tightened. Also, lubricate your chain.

Solution: If you are using spray on chain lube, dirt and grease may be thrown off the chain during normal operation. When a lot of grease accumulates on the chain tensioner (rubber cylinder) and swingarm protector (rubber bar) the chain will emit a loud sound as though running through sand. Scrape and wipe away the excess grease and enjoy the quietness.

Problem 7: - Exhaust Header got holes. Can repair?

Reason: Got one specific hole which is ok.

Solution: If unsure, post some pictures.

Solution: Replace gasket. Or #2, send it to Planet Motor (ahchong) to weld the holes, or get a second-hand exhaust or get one cheaper exhaust at LAB (must make order)

Solution: Fuel-air mixture likely too rich. Backfires when throttle is closed, due to residual fuel afterburning in the exhaust header. This is bad for the valves and the catalytic converter.

25: After turning off my engine there is a tick tick tick sound some where.

Reason: Exhast pipe is cooling down. Hot it expands so cold it turns back.

Solution: Do DIY exhaust wrap. Reduced backpressure = faster heat evacuation, leading to high speed silent running and silent cooldown after engine off. (Pandora's Kitten :3)

Problem 26: Cannot find neutral gear!

Solution: Gear oil not suitable, change different grade of gear oil (see gearoil thread for details)

Solution: Gear box dying.

Solution: Engine is overheated. (Running too lean/ Not enough engine oil. An overheating engine may cause excessive oil consumption, especially when using less tolerant mineral oil)

Solution: Clutch freeplay not enough

Problem 27: Handlebar position is not centered (while riding). Handlebars are "straight" but wheel points to one side.

Solution: Lock the wheel, grab the handlebars firmly and twist the bars until straightened. The risers are flexible to some degree, due to the vibration damping rubber washers. (Demonstrated by Planet Motors)

Solution: If your steering lock is spoilt, put the wheel against a pillar or a wall.

Problem 28: Bike hard to U-turn. Riding position not comfortable as handlebars too high up.

Solution: Adjust the angle of the handlebars. Loosen the bottom two screws of the risers, pull back the bars so they "rise" towards your face. This will give you a more relaxed riding posture and you are able to enjoy a greater turning angle at low speeds. If your handlebars are set to rise straight upwards forcing you to stretch forward and upwards to steer, your elbows will prevent you from turning easily at low speeds.

No worries bro. Appreciate your help and spirit. )

Still worried abt the problem. Also dun noe whether it's totally solved....

What is bugging me now is my Coe. Ending June 2012. Only 1 year to go. Doesn't wan to spend lots on just a bike. Transport serving only. A bike is still only a bike ultimately. However, still need a bike transport. Am thinking of selling or worst case, scrap at $200. Then gt another ta200. I love ta200. As it's very econmical. Dun wan to buy luxury ones. End up with installments. I just find it Bo Hua with interests. Since it's only bike.

Your thoughts pls....

Hi bro/sis, sorry to hijack this thread..Got my 8 years old TA200 2 months ago..Encountered 2 incidents with bike stalling halfway while riding during rain..The first time it happens, bike loss power and all electrical power loss..it was diagnosed to be the battery flat..After battery changed ok liao..The second time, the bike loss power and stop and i heard a "POP" sound! Quickly guide the bike with my feet to the road shoulder..At first i thought the tire punctured. But it was not punctured when i checked it.. The sound like comes from somewhere near the exhaust....This time round, electrical power is there as i can see the green neutral light when bike key is switched to "on"..EMAS came and towed my bike to a nearby car park..After a while, my bike can starts again and so far so good till now..i really dun know what happens and can any bro/sis help me in this? It can't be when during rainy weather this problem will come every time right? My frz who rode a phantom previously told me that this problem happened to phantoms often but he also dun know what is the problem and he changed bike in the end..I really want to find the root to this problem..Had read up on this thread and the problem that is similar is during raining, spark plug got wet and stalled..But my bike problem got a "pop" sound and so i am in a dilemma on what is the problem..Meantime, will refrain from riding during rain and will check weather forecast before riding.. Hope bro/sis here can help me..Thanks in advance!

You just diagnosed your problem; your spark plug got wet during a ride in the rain. Or perhaps your spark cable is old and the internals are exposed to the elements. Since I got some time, let me try to explain the 'pop' sound for you as simply as I am able to.

Air-fuel mixture enters combustion chamber from carbs -> spark plug wet -> cannot produce spark -> air-fuel mixture does not ignite -> no combustion -> un-combusted air-fuel mixture exits combustion chamber via exhaust pipe -> exhaust pipe is very hot (as we all know...) -> temperature in the header + pipe heats up air-fuel mixture -> air-fuel mixture ignites as it exits the exhaust pipe due to decompression (air pressure outside is lesser than pressure inside the bike's internals) -> you hear the pop sound as the ignition takes place.

If you're able to, whenever this happens, stop your bike at a sheltered area, remove your spark plug and clean it dry. Chances are, your bike can start again. For a longer term solution, consider replacing the rubber bits that are supposed to prevent these sort of things from happening. Hope it helps.

hi just to check, i just saw a tube at the bottom of my bike. it seems to be hanging loose. is this a problem? need to repair?

Pandoras Kitten 3 · June 7, 2011

hi just to check, i just saw a tube at the bottom of my bike. it seems to be hanging loose. is this a problem? need to repair?

This tube is most likely the:

1. Carburettor drain hose, the tube links to the bottom of the carb. This "vent" hole is usually closed by the screw located on the bottom of the right side of the carb, used for draining flooded carb or as a emergency feature if tuning goes wrong. Just leave it alone unless fluid constantly leaks from the tube.

jevan · June 7, 2011

so i can just leave it alone until i see fluid leaking right. Thanks Pandora.

Pandoras Kitten 3 · June 7, 2011

Yeah, nothing to see there, just a tube lol.

It's possible to run without the drain tube going to the undercarriage but in case someone needs to dump fuel from the carb.... it's a bad idea to do it onto the hot engine block/crankcase. Hence the tube.

jevan · June 7, 2011

I see. Thanks Pandora for the tips.

Think that is either the carb drain hose, or the breather tube that links to the tank.

The tube even if drop/ lost also no poblem, but leave it there better, help avoid having stains from dripping fuel on your bike.

Hi bro/sis, sorry to hijack this thread..Got my 8 years old TA200 2 months ago..Encountered 2 incidents with bike stalling halfway while riding during rain..The first time it happens, bike loss power and all electrical power loss..it was diagnosed to be the battery flat..After battery changed ok liao..The second time, the bike loss power and stop and i heard a "POP" sound! Quickly guide the bike with my feet to the road shoulder..At first i thought the tire punctured. But it was not punctured when i checked it.. The sound like comes from somewhere near the exhaust....This time round, electrical power is there as i can see the green neutral light when bike key is switched to "on"..EMAS came and towed my bike to a nearby car park..After a while, my bike can starts again and so far so good till now..i really dun know what happens and can any bro/sis help me in this? It can't be when during rainy weather this problem will come every time right? My frz who rode a phantom previously told me that this problem happened to phantoms often but he also dun know what is the problem and he changed bike in the end..I really want to find the root to this problem..Had read up on this thread and the problem that is similar is during raining, spark plug got wet and stalled..But my bike problem got a "pop" sound and so i am in a dilemma on what is the problem..Meantime, will refrain from riding during rain and will check weather forecast before riding.. Hope bro/sis here can help me..Thanks in advance!

Bro I live in Yishun too, where do you live, I can go tighten the spark plug for you.
