Thanks Fagan, I remember them too. 'Bad Attitude' is what I think they called their Igniters. I seem to remember that they worked real well for a couple months and then I had a 'bad attitude' when they crapped out. Just kidding, I appreciate the help. Chris
Chris, the 86 X-2 650 igniter has NO rev limit

) The later 650 cdi's do but not sure what that limit is. Best of my recollection is there was a co out of Texas I believe 'Dale's' maybe that modified the 650 boxes.
