im riding x1..ive nvr had prob wit my bike untill my piston was jam..nw its already repaired bt i have to throttle to actually start compared in de past i juz had to kickstart one time juz to start..

[muhdhaikal]

perhaps u need to check ur idling rpm setting?

[desewer]

Good point. Maybe the mech adjusted the carb tuning so that at startup you need to throttle a bit but once warmed up the engine will idle at a much lower rpm thus saving fuel.

 

Just in case, check your choke lever to ensure that it's fully in or out, not halfway.

hmm probably your idling RPM setting. Set it to 1.5. Correct me if im wrong..

[ahsnow]

think not wrong is yo rpm too low try to set it higher n see it works??

Pardon me for interjecting but I'm actually wondering how would a 4-stroke bike could easily have its piston seized up when the engine of 4-stroke bikes are constantly being lubricated with 4T oil

i'm guessing this....

 

dun check the engine oil level long enough... 'eat engine oil' and the jam would occur soon enough...

oh let me assure you... it happens.

 

It happens when the rider has the bad habit of dropping gear at high speeds to magically get more power.

Okz...

I suppose doing that actually makes it almost the same as a rider being harsh on his 2-stroke bike
