I have a weird problem with my bike, it's been going on for a while. At first the bike had a missfire problem that I traced to a bad # 2 cylinder coil. After i replaced that It wouldn't spark, no matter what. I have replaced the crank position pickup, the battery, spark plugs and the ECU and I tested the regulator with a known good one. If anyone has a clue, has seen this before or has a guess, please let me know. Thanks allot.

Can you hear your fuel pump run. Also there is a main fuse for the ignition that if its blown you wont get nothing i believe its up by the turn signal fuses right by the speedomoter hope this helps if not let me know.

Fuel pump works, but the tank is off the bike right now. fuses are all good. I bought the bike used, and found out after about 4 monthes that it was wrecked, but it ran great. up until the missfire problem, it was fine. then it just started to go downhill. after replacing the $500.00 CDI box i thought i had it fixed, but still no spark. Everything seems to work except for the spark.

Another little thing that gets overlooked is the plugs. Replace the plug and see if that works. I have chased electrical gremlins for hours only to find the plug was fouled out. Sometimes they look OK and still dont' fire. If you have a known good plug in the plug wire, ground the plug and see.
