Ok I've read all over this forum and read lots of posts about engine not starting and how to clean them and such. But I still haven't found my answer. So I've got to be annoying and ask why my engine won't start. It is an xs400rj 1982.
Back story. Been running good for last few months but running very rich cause i hadn't had time or knowlege to tune it. Then Crashed it into a wall. Minor crash just bent the forks. Engine seemed to be running very rough after that and was difficult to start and keep running. Recently I pulled the carbs reset the idle screws to stock 1 1/2 turns and synced the carbs. Ran EXCELLENT. Beautifully clear hum. Turned it off with the kill switch put the gas tank on it now it won't start. literally 2 minutes later. WTF? Took the tank off and it still won't start. Using a makeshift bottle gas tank. Yes the kill switched still isn't flipped.
No back fire almost no popping, it's popped twice in an entire day of cranking it. nothing. Pulled the carbs again they are full of full and floats look and move good. Nice and clean. No blockages. I could do my hair in the reflection of the carbs. new battery strong crank for long periods of time.
tomorrow I will check for spark. How do you do that. Will it work like a car if you touch the spark plug to engine block to ground it?
Thats my only guess is that maybe theres no spark.
Any suggestions?
