Thanks for the help, I've tried David Silvers but he has only a few parts for the 250, I have seen Honda trials.com but it's only a supplement to the tl/125 tlr200 workshop manual.Also tried csmnl but they don't list the 250. Does anyone know if engine parts from the 200 will fit or I'm I better looking for the rs250 parts which I guess are even harder to find. I.m trying to do a top end rebuild + cam chain complete for now.But who knows what else I might find.
