[Technical] Possible Solutions to your Phantom's Problem

[sawfly]

Anyone here has done valve adjustment before? The valve/tappet clearance thingy. If so where you guys did it? I need to do mine, valves getting noisy and bike is incredibly hard to start without trottling a little.

 

see this from eons ago leh. http://www.singaporebikes.com/forums/showthread.php/321739-Valve-Clearances-when-to-do

 

anyway i also got similar problem. nowsadays every morning after start engine must open throttle for at least a while or else the engine will die off.

i dont have to do that when i go back at night though. really related to valve clearance?

 

also if do valve clearance need considered top end overhaul?

Nope overhaul is totally different from valve adjustment aka tappet clearance adjustment. This one just need open 2 small caps at the top both sides of the engine, basically 1 at inlet and another 1 at exhaust there. From there you use a feeler gauge to check and adjust clearance. I have never done this before so i dont know how to do it properly. Need to set at Top Dead Centre and adjust one.

Wah ya ah didnt think about that also hahaha

[naim]

Actly possible w/o removing too much from top. Cover enuf alr. Because to set TDC, marking will be on the flywheel (can see frm left side of engine by removing the circular covers)

makes total sense now.. does anyone know still why early morning have to throttle a bit or else engine will die after starting?

any bros know the average lifespan for bearings for phantom? I was told there are 3 sets of bearings at the rear wheels, one for the sprocket, 2 for the wheels and last about 9 months. true? how often should we get it replace?

9 mths? i hv been running my set of bearings since last year around this time and all's fine. i think best to gauge when to replace is to check the bearing every now and then to see if its okay instead of relying on an interval..

[naim]

9mths too short ah. Either the mech replace with cheap parts or just fake you. Have u seen the bearings for urself? I think every tyre change is good enough. Another way to check is jack the bike and try and shake the wheel around. Spin it as well. If no play and no grinding noise when spin, bearings are still good.

thanks for the advice!

[Spark_135]

9 mths really short. But dont be keh kiang like me hahaha. Change bearings barely 2 months go ride at Jalan Bahtera dirt road. Couldnt stop in time or swerve to avoid big pothole. Went over it instantly damage my left bearing and destroyed my rear box.

 

Anyway update of my bike. Left my bike overnight at my bike shop for it to cool. Next morning will be doing tappet clearance and carb cleaning.

hi all,

 

i just noticed my phantom is leaking fuel really bad this morning.

anything i can do to stop it ?

thinking of calling a tow to get it to workshop asap.

but since the leak is so bad wondering whether i can stop the flow for now.

 

any ideas ?

Shut off the pet cock when u off engine. Pet cock is on the left side of the tank, has a knob that shows On-OFF-RESERVE (or just ON-OFF for some models). Immediately rectify the leaking problem. Leaking petrol can cause your bike to burst into flames anytime.

i think also have to identify the location of the leak.. skali it begins before the petcock...

 

btw spark135 do update on whether the valve clearances do help.. getting sick of revving the engine during starting..

I just replace a 2nd hand Rear rim and changed all the bearings.

 

Totally forget about checking my bearings after 2 years... Total of 3 bearings at the rear and 2 in the front. Make sure u get those bearings with cover. Don't get those chiong bearings with ball bearings exposed..

 

Thou it come cheap but wont last.

[sawfly]

turned out that my hard starting problem was due to a dirty air filter.. !@#$%%^.. replaced with a brand new one!

[sawfly]

add on to list!

 

:PPhantom 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).

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, petcock off.

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

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.

 

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.

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.

 

 

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

Solution:

- Send to bikeshop.

- New dipstick costs around $11.

 

 

Problem 9: I have tried everything but to no avail. Any tow numbers please?

Solution:

- 67474740 Tiko cheong.

- 64560018 Wing Yap.

- 97384501 => Hello, you the tua chia one?

 

 

Problem 10: Engine Part Leaking Oil

Reason: Gasket Spoilt.

Solution: Bike shop, get it replaced

 

Reason: Cam chain tensioner spoilt.

Solution: Bike shop, get it replaced

 

 

Problem 11: When riding, bike lean to one side. Let go of handlebar, steering was shaky and wobbling

Reason: Might be steering cone problem.

Solution: Go bike shop to get it fixed. May also need re-alignment.

 

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)

 

Reason: Air suction valve spoilt. Backfire occurs after closing throttle suddenly.

Solution: Replace air suction valve.

 

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.

Solution: Fuel/air mixture too lean giving poor acceleration and a hot engine

 

Reason: Your brake is dragging

Solution: Check wheel spin, check the brake pads if its time to replace, check if brake caliper mounted properly, check disc rotor warped or not

 

 

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)

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.

 

Reason: Air suction valve spoilt. Backfire occurs after closing throttle suddenly.

Solution: Replace air suction valve.

 

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

Solution: If cannot find neutral when engine is hot but fine when engine is cold, that means engine oil has degraded and cannot maintain its viscosity at high temperatures. Changing engine oil should solve the issue.

 

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

 

Problem 29: Engine oil disappears at a fast rate

Reason: Piston ring busted.

Solution: See mechanic. Top overhaul probably needed.

 

Problem 30: Side stand broke off with mounting lug.

Solution: Get a mechanic to weld the mounting back.

 

Problem 31: Engine starts but stalls after short while. Repeat cranking will not start bike. Bike starts only after moderate to a lot of throttle and revving.

Reason: Clogged up air filter.

Solution: Replace filter. Filter should be translucent to light.

Shut off the pet cock when u off engine. Pet cock is on the left side of the tank, has a knob that shows On-OFF-RESERVE (or just ON-OFF for some models). Immediately rectify the leaking problem. Leaking petrol can cause your bike to burst into flames anytime.

 

thanks for the reply guys, yeah I can stop the leak by turning off the petcock. I took a picture of the leak posted below for those who would want to know the exact issue.

Have it checked at the workshop. they say there's a part called *something* jet got problem which suppose to control the overflow of fuel.

Got it fixed last month with a 2nd hand part, but in a month now leak again (although not as bad as last time). Going to go back to the shop again -_-

[ATTACH=CONFIG]286139[/ATTACH]

 

is the part circled a tube connected to the bottom of the carb? that one is the carb bowl/carb overflow drain tube..

[ezzyoiler]

you have what is known as carb overflow problem..

the shut of valve at the bowl cannot shut off the petrol when bowl is full..

at this condition your bike will stall when u try to increaee rpm by throttling..bike cannot be ridden as it will stall frequently.

sometimes it is caused by dirt etc stuck at the valve...preventing it from shutting off completely...in your case worn out needle/jet

[snookie51]

I am trying to get that piece of flat rubber which serves as a protection against the chain grinding the swingram when there is excessive slack. I don't know how it is called. It is located after the front sprocket and is apparently secured with 2 screws. Mine has worn out quite badly allowing the chain to gouge a small hole on the swingram. Can anyone tell me where I can buy it and how much it costs? If not availble, then I'll need to improvise. Your help will be very much appreciated.
