Re: no spark!!
I had the same problem with my 89 85. I checked everything and could not find the problem. Since it is an 89 I decided to replace the trigger, stator, coil packs and cdi boxes and nothing worked. I finally got fed up and took it to a Force tech and he could not figure it out so he put all the old stuff back on and got it running. He charged me $650 and he still did not now what was the problem. Like everyone said, get the manual, check all the components individually and see what happens.
