Need front and rear sprockets for 1975 250. I believe stock were 13 frt, 52 rear. I mounted a 14 frt and 56 rear some time back in a 520 chain size (14 frt was available). This gives the same ratio, but I fear the 14 with chain may contact other fragile components. Any advice on use of the 14, or availability of the original sprocket sizes??
