Well at least I know whats going on. When I first got the bike I had the controller fail in teh first 20 miles and got a new one from EVT (6 months later) but got one, swapped it out and it has run fine for 3 years and 2700 miles, until now. I ran it in hot weather and as fast as it could go for about 10 miles and the next day it started acting up, jumping, lurching and growling on starts. It sort of moves but this is exactly what it did right before the controller failed last time.
So my question is what controller should I put in it now?
Which one and from where?
