I installed the Z start pro model into my 07 wr450f. The install was a breeze and after the initial break in I couldn't be happier. I rode 40miles without an issue. Then the following day 20 minutes into an enduro the clutch began slipping excessively to the point that the bike was unridable. I tore it down at home to find a burnt out clutch. I replaced the friction plates and doubled checked my work and even used Rotella T 15w40 as recommended by rekluse. Today Ive been riding it on the street and the issues are as follows. 1. Idle has to be set very low or else I cannot shift between gears 2. There is no manual clutch over ride whatsoever Im at a loss as to what the problem is. Any help would be great.
