Y HELO THAR!

 

Give you a call sometime. Or you could just give a call sometime.

 

 

 

SMS me ok. I really forget to save your number, really sorry.

[firefox87]

WELL GUYS...

 

Finally I hit 60k KM for the past 1 yrs and 10 months...

 

60km only? mine still at 40+k mark. but after calculating, that means 30km in just 8 months!!! and the furthest place i've gone is danga bay. lol..

 

Hi bro, may I know how much does it cost for the spark plug and plug cable and how do we go about changing it? Hoping to save more fuels as recently had been traveling more often and pillion.

 

Hmm... is there any guideline on the air/fuel ratio? Not too sure how to determine mine.

 

Hi bro, can teach me how to take out the exhaust and maintain it? Thanks a million in advance.

ya la. how to maximise fuel efficiency and set the bike to run long distance better. the only thing i did is to change my rear sprocs to a size 38. i need some help too!!

 

Realized I don't have any pictures of the suspensions themselves. Heres a pic of the tail end of my bajaj with all the boxes on. Tires are Shinko tires. Looks like michelin pilot, eh? bought the tires F + R for 150 at Chong Aik @ 26 Joo Chiat Road. 180 for a pair of BT39 tires is ****ing ridiculous.

 

Makida sussers can be had at lorong bapok for less than 200rm.

 

i paid my friend $100. its expensive, but you can call it "members price" i guess. rezeki halal dibagi.

 

anyone else wanna change suspension? count me in! bro... u tell me too late sia! i just changed both my front and rear tyres for $193 over at UM. pocket burned!

 

anyway, i had my lunch at Eu Tong Seng foodcourt, the one behind Bugis Junction and saw this cool pulsar!!! The pulsar head has been totally ripped out to make way for a super 4 headlamp with the analogue meter remaining and IU unit on top of it. then, got belly pan that look very similar to the bike. people would have thought that the belly pan comes along with the bike. anyone seen this bike before?

Oh yeah Lucky21, sorry for the air/fuel ratio question, I missed it. It is compilated. Ideal ratio is usually range from:-

 

Air:Fuel = 20:1 (Lean Mixture - More power but damage the engine faster)

to

Air:Fuel = 14:1 (Rich Mixturre - Lesser power but lengthens the engine life by using more petrol)

 

Easier terms to understend, your spark plug head gives a good indication of your combustion ratio. Try removing it and see:-

 

- Very black with thick carbon coating at plug tip means - Your fuel is too much.

- Black plug tip - Still ok with a acceptable combustion ratio, fuel abit to much but ok.

- Brown plug tip - Perfecto, perfect combustion ratio between air and fuel mix (also gives the max combustion power out from the engine.)

- White plug tip - too much combustion air (waste of power and also can damage the engine if the plug is too white, hard to start engine also).

[arifisa]

Pulsar is a very good bike in terms of good milage, longest I try was 850Km in a single tank with a LD Spec and a 38 sprocket rear, but very board to ride at a very slow speed. But never mind due to fuel prices like sky high. Better be save money than no honey.

[silverboi]

total pet when u wan to do ur bike jio me ya hahahahaha....

[Nemesis]

:cry:

 

see what i mean ??!! cry again... just like usopp...

you seem to have done some good and practical stuffs to your bike. any idea what's the initial damage to fix up and change all those stuffs? for me, i just do basic only. change $10 EO and cheap spark plug, also don't know what brand. nothing else done unless my bike got some problems and the mech says my bike gotta change this or that. every month, i go shop ask if got any problem with my bike. they say ok. no problem. but i feel as if it's not shiok! still wondering if it's the quality of the bike or the condition of the bike.

[GoofRider]

talking about P200 fuel injection. has anyone ask UM when roughly they bringing in the p200 fuel injection.. gotta start to plan liao..

 

if UM really bring anytime soon, guess me replace my horse.. hee.

i've always aim at the p220 cos of the Fuel injection... and now knowing

p200 gonna be a Fi... hehe...

 

really really can't wait!!

[SC Gaban]

Yeah that one but the one I brought is slightly dirrerent from the picture in terms of packaging. The cable is a dual core channel type with silicone coating. You are right.

 

thnxs bro. but w do u fix it? can u give a sample pic?

[breadman]

Nemesis, how about organising a small get-together and collate the mods we wanna do? Perhaps can ask for small-bulk discount

 

i'm interested in changing spark plugs and cables. my NGK plugs used for about 10k mileage liao.

so how u do get 20:1 and 14:1?

U quoted 4 ways to check if the combustion is at the optimum or worst stages of tunning. Can explain if u tuned ur bike after every plug change to get the optimum or otherwise?

Do you noe that the air:fuel ratio is independ for all bike or other stuff are related to the A/F ratio?

 

Changing to dual/twin core plug cable does increase the power i agree, but changing the plug, plug cable and the intensity of the power/electricity supplied to the plug does make it a risk for the piston head overheating. Ask experienced mechanics they will know the consequences.

 

May i question what is the TDC of the piston, CP and combustion temperature in the combustion chamber before all the mods are done and after.

 

Thanks.

How to tune air/fuel mixture. Can you take photo and explain to all of us/Pulsar rider.

It will be great info.

[breadman]

Sure why not... u help me think think...

 

ok boss

 

i think.. u should organise it :lol::lol:

[SuVespa]

I suggest the meet up at kranji MRT station at the MRT side...theres a small loadind/unloading area after the bus stop to park our bike

[arifisa]

so how u do get 20:1 and 14:1?

U quoted 4 ways to check if the combustion is at the optimum or worst stages of tunning. Can explain if u tuned ur bike after every plug change to get the optimum or otherwise?

Do you noe that the air:fuel ratio is independ for all bike or other stuff are related to the A/F ratio?

May i question what is the TDC of the piston, CP and combustion temperature in the combustion chamber before all the mods are done and after.

 

Thanks.

 

1. 14:1 to 20:1? Simple, it all ends in the Hydrocarbon Chemistry. Calculations of C5 Hydrocarbon base petroluem what humans call it gasoline or petrol in Asia language. A A:F ratio is base on how much air is needed to mix with petrol to create a good combustion range.

 

2. Tuning - I travel for at least 100Km before I tune my A/F ratio by observing the plug there after. This apply on my old scrapped modified Honda CBX 200S. For new bikes fresh from the factory, it alrady has been tune to get the best optimum ratio, avoid personal tuning if not nessary. Carburator tuning and cleaning need some skill to attend to it.

 

3. Not all bike have the same A/F ratio, it depands on the engineer who design the engine and determine what is the best combustion ratio of the engine to run. but the range of 14:1 to 20:1 is always apply, even to other types of internal combustion engines like cars and vans(petrol engine only).

 

4. You are right worrying about piston overheating, like wise before doing something, think about the problem that can occour and the solution that can compensate the problem. That's why it takes me 2 months to do my home work before I modify my engines. You don't just go to any shop and modify the engine to increase power of save fuel comsumption right. Motorcycle is a rider investment.

 

5. Rules of tumb, modify engine or any other thing need some thinking and homework, don't just think about want to do it. Example, running cost, realibility, engine stress, fuel comsumption, battery consumption, expension and contraction of engine component, temperature and other thing to consider also.

 

6. Piston TDC - Top Dead Center: At the point where the piston is at the higest point of the combustion chamber just few miliseconds before the spark ingites the air fuel mixture which force the piston to move back down again and repeat the cycle.

 

7. Combustion tempurature in the cumbustion chamber can range from 460 to 750 degrees Celcus. But to get accurate reading you need a special device that can measure the temperature in the combustion chamber (device is very expensive, even I can't afford it. hahaha.

thnxs bro. but w do u fix it? can u give a sample pic?

 

If I want to take a picture, I have to remove the tank again. Lazy ah. But if you still want the picture wait till I buy a new P200 Fi. ok remind me....

Wah bro are u a mechanic?

Cause you sound like one...

kekeke...

ok done... change already

[Lucky21]

Spark can cost from $8 (cheap copper plug 2mm) to a expensive $35 (0.7mm Iridium Racing Sperk Plug). I recommend a Platinum 0.9mm spark plug, due to it's slightly stronger spark and lifespan of the Platinum Element. Usually Platinum base cost aroung $10-$20. A low resistance spark cable usually cost aroung $35-$65. $65 is the one which I brought and install it myself.

 

The way you ride is also important when come into speed and pick up. Tire pressure need to be higher by 2-6psi for the rear tyre if you are going to pillion a passenger. I usually ride at night, this also contribute to higher milage.

 

What Nemesis ment if I am not wrong is by taking care of the exhaust external, black exhaust tend to rust and turn orange due to water and oxygen in the air we breathe. This is normal as pipes usually make of carbon steel (usually small bikes and stock exhaust). Usually rider take it out and spray it black to minimise the rusting of pipe external. Depand on the skill level of the rider who take care of his/her bike.

 

If you are skill enough. You can even maintain the exhaust pipe on your own by doing yourself without going to the shop to do it for you. Like taking it out clean it (externals) and spray it with high temperature spray paint.

 

Thanks for the explanation.
