Shaw;
My bike 07 sprint is ported case and matched (Devin) with a 26 frnt tooth and 22rear and I'm experiencing the top out as well at abt 45 mph. so are you recmmding removing the whole cdi on the a55 and exchanging it for the a35 cdi? I know it's limited as well but i heard (as you might be referencing to) that it's a simple wire that you cut out. oR DO YOU RECMND GETTING A CDI FROM A DIRTBIKE. Me and Devin from motion left are trying to evaluate the best way to get this to a 55-62 mph and my current miles are true gps'd miles. Would appreciate your input as I know you're hitting these speeds with your tomos aiero. Thanx
