It semed like a lack of fuel. i cleand out the cab and flushed the tank. It still doing the same can any one help!!!.
January 28, 200916 yr Moderator Try pulling the fuel feed pipe off the carb, open the fuel tap and run fuel into a container, you should have a healthy flow rate, check this first

January 28, 200916 yr Author when my bike cuts out if you leve the bike for a min it will rey start and go fine then it will do it again and again
January 28, 200916 yr Moderator yes Its either running out of fuel because the carb is only filling slowly......Or running out of sparks You need to find out which is the case, next time it conks out, pull the spark plug and test for sparks, it might be the pickup coil breaking down as the engine warms up, then as it cools a little works again...and so on and so on, you say you flushed out the tank...what was it like?

January 28, 200916 yr Did you clean the screen in the fuel tap bowl, I know you said the flow is OK, but with rust particles you should have done this anyhow. Is the air vent hose thingy blocked coming from the tank? Try riding the bike with the fuel cap loose or removed (just for testing) and see if you are able to run it for a decent length of time.
