Starts on a backfire...

[QUOTE="Morvo, post: 991278, member: 64644"] My 1995 KX250 has been having serious problems the past few months and I just can't get my head around the problem. It all started with a faulty pickup coil which I replaced with an aftermarket one which I had to fiddle with to get it to fit, it worked fine but the bike kept on fouling plugs and got gradually worse. I changed the jets, leaned the mixture out, changed rings etc... and it was still fouling plugs. In the end I decided to buy a better pickup coil which is a direct replacement for the original kawasaki one. After fitting this part the bike will only fire on a backfire, inbetween a few kicks where the kickstarter will kick back violently. Once the bike has started it won't rev up without popping and backfiring, if I release the throttle it will die, and if I hold on the throttle it will pop and die! I asked someone about the pickup coil wiring as there are only two wires which I had to solder to hook it all up, he said if I wired it on wrong the plug wouldn't start at all, but it does, really big blue spark. What things should I be looking at to resolve this tiresome, tedious, ass of a problem? New stator plate, new CDI unit? The flywheel wooddruff key is still in place and the flywheel is tight. :( [/QUOTE]
