Engine idle up and down and stall while riding/stationary.

 

please adv.

 

could it be the fuel injection or??

[stsoh]

have u try fuel injector cleaner additives???

fi cleaner additives fix with fuel, u can buy it from any accessories shop.

other possible problem is water in fuel tank.

Yes I had the same problem and it was due to water in the tank and carburater . Can be rectified by washing of tank and carb . Possibly fine rust in the carb that has accumulated over the years .

what bike are you riding?

[bobiee]

do some injection/carb cleaner and wash your tank .

E mech can increase e idling speed rite?

It would help alot of people know what kind of bike you riding.

 

Varying engine rpms at idle for 4 strokers is valve clearance issues and in the 2 strokers is fuel mixture issues....most of the time.

cleaning of carb is easier than u tink. look up at youtube. alot of tutorials and google for more read-up. and carbs is a very universal design. once u understand the basic mechanisms, even if ur carb differs frm those in d video, its easy to spot what is what. get a can of carb spray (STP brand), sum wrenches and screwdriver (+ & -) and u r good to go. unless if urs is like 4-cylinder, then more troublesome lar.

Got dat problem when riding my cbr400 fireblade.. Went to various bike shops to rectify e prob but failed !!! Spend hundreds of dollars n time on cleaning carb lah, spark plugs lah, air filter lah.. Lastly went to sin boon n it takes no time for e "doctor" to rectify it.. N e "culprit" is 1 of e spark plug hose leaked !! Its a very tiny leakage but have caused alot of "problem"... N e damage ? Less than $50/= ...

could be due to water in tank or near sparkplug area
