Can any one help with some advice for a kart republic axle keyway. Having trouble trying to find some for the Hub holes as my my KR axle has 3 holes but the centre one seems smaller so the 3 peg keyways dont fit. is it just a case of drilling out the centre hole a bit bigger or are there different keyways for the hub holes. If so where can you buy them. The sprocket carrier and brake disc keyway holes are all the same size ???
Just use 2-peg keys.
