Kawi is STILL having issues with the Zx10 tranny? When the '04 had problems in race trim, we were changing out the entire transmission and shift assemblies EVERY 200 Kilometers. (Engine out every day..) Dunno if it got fixed for '05 cause I left the team. May I suggest: Change out the spring on the shift spindle (part #92145B in parts book) with something heavier, like the one out of the Voyager.
