It is is firing out of the carb and the exhaust, the timing must be off, but also slipping. Is the flywheel tight?

so yo have an electronic ignition then. Id be suspiciious of the little 'black box' that comprises the system.

Electronic ignition is teriffic while it works, and they have a good track record. When it quits ... id much rather work on the points type.

Aside from checking the adjustment on the electronic ignition, I dont think there is much you can do with them

have you tried testing the regulator rectifier i am sure this has an effect on the charging circuit also is it definetly the charging circuit not working or could the battery be not holding the charge thats put to it.

I have a 1982 kawasaki KLt 250 three wheeler and Im tring to find a wiring diagram so I can get it running Im having troubles finding a diagram
