l have some problem regarding starting of my motor cycle.
My motorcycle is just 3 months old.
l use my motor cycle after every 7 days.

the motorcycle starts well when the engine is cold if l choke it . But just after starting, suppose after 2 seconds , if l try to ride it , the engine stops or the speed of the bikecan not be controlled by the throttlefor 1 minute. If l ride at that time in this condition for 1 minute, everything will be normal.when the engine is hot, it works well at that time and the problem doesnt occur.what can be the cause of it?

Rev the bike a few times to warm it up.

Sounds like to me its just a bike that needs to be warmed a bit before you got on it.
l had a dirt bike once that had to be warmed up no less than 3-4 minutes before l could ride it or it would bog when l hit the throttle. None of my friends (with the same exact bike) ever had a problem.

So every machine has its own idiosyncrasies.

And this is a RACING question how ????

Just Rev the engine a little before you ride. Dont Over rEv though as thats a bigger problem.

you will not get the you want by posting this question here in the RACING forum. try asking this question in the motorcycle area. guardrailjim can help you there in that forum..

You are rambling,always give this information,Make,size,model and year.

l believe that the answer to ur question is to Yes let the bike warm up. u do not have to sit there & rev the crap out of it tho. it takes a good 2 minutes to let the motor warm up enough to ride. ''The motor has to warm up because when it is cold the cylinder is small & hugs the piston tightly, when it warms up the cylinder grows a bit'' for the shear safety of not blowing up ur bike let it warm up. then once the bike warms up & u start riding it will run a bit funny for a minute then everything should be OK.
