03 Z 400 it cranks fine but no spark, I have been able to push start it a few times. Pushing it aint much fun. Any and all help would be great. Thanks.

 

pull the plug out, start crankin it for about 10 seconds at a time with the plug OUT and the choke OFF, do this for about 6 to 7 times, put a NEW plug in, drain the old gas, put fresh premium in, make sure the choke is ON all the way, and it should fire up no problem for you...i had this type of problem here and there, but a new plug and fresh gas usually did the trick.... make sure you have the right plug, get a NGK: CR7E You'll be up & running in no time...

 

there is 5 things that cause no spark, 1 ignition coil, 2 spark plug,3 generator, 4 CDI , 5 pickup coil, I would try a new plug first

 

Thanks for the info. I changed the plug but it still will not start. I was able to pull start it though. After it was warmed up it would restart. I let it set for an hour and now it won't start again. I 'm still scratchin my head.
