I drug this project out from the back of the shop where it's been ageing for the last 4 years. It's a honda MT125 frame and running gear with a bunch of CR125m parts on the motor. Freshly machined '75 CR125m Jug, wiesco piston, CR125m carb, CR125M CDI, CR Pipe, CR shocks, rebuilt the forks, etc. I got to ride it once, for about 1 minutes back 4 years ago and then it stopped running and I could never get it to do anything ever again. I spent a ton of time troubleshooting and I was so fed up of working on it that I just covered it up and put it away. I I've got good compression, I've got spark, I've got fuel. I've moved the timing plate around every which way and it. just. doesn't. do. anything. I've got a sealed crank case with good seals. I've checked the coils on the CDI's resistance, they were fine. The only thing I can think of is the CDI control box has a malfunction of some sort but I've got spark at the plug? I'm pulling whats left of my hair out. Other than just shotgunning parts at it i'm at a loss.
