Wacking your bike can only clear the recently deposited carbon. Those that have been left there since the beginning of time is difficult, if not impossible to remove as hardly people open their exhausts and headers to decarbonise 4 strokers. They usually only do that for 2 strokers. I'm not sure if its possible for 4 strokers anyway.

Carbon deposits do not depend on the type of fuel that you use(well...mabbe abit). The main issue is the tuning of your bike. Carbon is the product of incomplete combustion->Simply means that your bike is not burning fuel efficiently. This in turn points to the tuning-air/fuel ratio is incorrectly done, resulting in larger amounts of carbon deposits.

 

Basically valves control the power of the bike, when the rpm of the bike reaches a certain level, the different valves will open allowing more fuel/air to enter the combustion chamber.

When valves become too worn out, they become ineffective in regulating the amount of fuel/air into the combustion chamber thus affecting the overall effectiveness of the machine.

 

I'm not sure how much it costs... probaby in the range of a hundred or 2. Take note that the shims will cost $$ as well to replace. And while you are at it... get the mech to check on the timing chain and other components as you will seldom open the engine. And this will probably take days to a week.

if ya doin that, do that note that u'll be drainin the coolant as well.

(esp for those who use water wetter or maxima blablabla. pls brin along ur coolant and distilled water. do check on coolant hose/pump, radiator cap etc also)

 

and since the carbs will be out, i usually check on them as well.

good chance for u to see if all the gaskets/jettings etc are workin fine

 

wat i did was to grind the valves + clean the ports/piston heads etc at the same time.

 

but since this MIGHT lead to carbon deposits 'droppin' in, i'll change the 4t as well.

 

since we dun open up the block that often, my as well do a through job while we're at it eh?

 

for those who are keen, the headers should be out also. good chance to play ard with em.

 

amazin... the rubbish i can type in my free time. hahahahhahaa

[diablo_gixxer]

u guys r like d manuals printed out 4 g4s! haha! thanx man... or shud i say men... and how would i know if my valves needs servicing or repair?

[Guest TheSquid]

tick tock tick tock (think peter pan?) hehehe

 

anyways, i usually do it no matter what when i get a 2nd hand bike

Yeah same here... rode mine for a year and when the time came for tuning i did everything together.

 

But it also depends on the age of the bike.... for old bikes like ours, its better to do it at least once while you are riding it. Cos you don't know if the previous owner has done it before and when tat was done.

which part do u find chim and need help in?

 

when u say tuning, i presume u r talkin bout the carbs.

servicing (cleaning) and synchronisin ur carbs usually cost $80

price does not include replacement of faulty parts

(eg. carb floats, main/pilot jets etc)

Careful with that smiley man... you might just get a warning letter.....

Anyway the cost of valve clearance, tuning, checking, replacing worn out parts etc etc should set you back by about $400 or so.

So start saving up if you are going to do it!

go back find them.think they never synchro properly ba,or ur idiling too low. Worst case is ur carb float need to change and tat's gonna be expensive .

can't say much.... need to feel it den can know. mabbe it WAS low on fuel?

 

Try riding it till its warmed up and see if it still stalls. Check on your idling as well... should be ard 1k+ abit.

 

Another thing to test. While riding and holding constant throttle, do a sudden increase in throttle and hold it. If the bike seems to struggle for a moment and slowly climb its way up den you are indeed low on fuel.

 

This also applies when your spark plugs have fouled. Tell tale symptom of fouled plugs would be a chopper sounding exhaust when you start your bike. Lousy response from bike when revving. Lack of pulling power and lastly, take some water to your bike before you start it and apply onto the headers. den start your bike and rev. If any of the headers evaporate the water much slower than the others than congratulations you have a fouled plug.

 

Otherwise if you live near boon lay i can help you take a look tonite. gimme a call if you need help. my no can be found in the link in my siggy.

[kohjiasheng85]

thanx alot fellow gixxer.. when my bike is ready den i organise a outing for gixxers.. tml i wil go find them and solve the problem..

[diablo_gixxer]

got any shop to recommend tat does very gd tuning?

[BOGEY102.1]
