Hey,
About 6 months ago, my Thumpstar stopped working for no reason at all. I checked the usual spark plug etc etc and narrowed it down to the magneto (stator plate).
Anyway, i got a new magneto and put it in and it started, however, its still not running right.
When you start it, if you dont give it half revs, it wont start. Once its started, if you dont keep the revs up, it will just die. Also, when running, its running like a slug. Backfiring, sluggish and it just wont go anywhere. You can have it flat out in 3rd and it will doddle along at 5mph and make a loud exhaust noise, but just not go anywhere.
I'm out of ideas with this bike.
I dont know how an incorrect magneto could cause this, so im ruling that out. I've tried a different spark plug and cdi and coil but it didnt change anything.
The only thing i can think of, is that the carbs knackered??
What do you guys think! I'll try and post a video of the bike running soon.
