Spark plug

Recommended Posts

Anyone have an issue with getting a spark plug to seal ....it seems to bottom out but the crush washer doesn't seem to crush and engine has lost compression when kicking so I know its an issue with the plug ...I will be removing the tank tomorrow to get a better look ...any suggestions would be appreciated

Murphy's law strikes again. ... went back to basics ...decided to keep it simple ... after checking things over and talking to a local dirt bike shop ...turns out I had a tight exhaust valve .... after a trip to the part store to get the only two feeler gauges I didn't own...the bike started after two kicks ....warmed up ...idled well ..runs well ....just a huge coincidence that this happened after replacing the plug

the amount of escaping air that would be needed to noticeably reduce compression during a kick start would need to be a removed spark plug  not just a bad seal

 

glad you got her going  nice problem solving
