Question about kawasaki KX 250 Motorcycles
Apart from running fast, when turned off there is a small backfire
I am not sure what you mean on the "running fast" statement. If idle speed then turn the idle screw outward to slow down the idle.
The backfire is caused by turning off the ignition key when the bike is at high revs. let it idle down THEN turn it off. The backfire is there because the carb idle circuit is active anytime the piston is in motion. Gas goes into the cylinder as the bike revs down then a hot spot in the exhaust pipe finally ignites the built up gas. There is your backfire.
Is the running fast question answered? Give me more information on the problem if it isn't.
Please rate this answer. Thanks njv6!
