HELP! I have a Crain HI- 4 ignition on my scoot with a miss. Is there any way to check the ignition module? when I twist the throttle in each gear as it starts to accelerate I get a miss fire. I had this problem before and they had to replace the module at a cost of $300. It's doing exactly the same thing as before. I have checked everything else and find no problem. I m thinking of going to some other ignition system. I have spent enough money on Crane crap.
