Uh, nice!
I have some problems with my rear not line up with the frame/sprocket to sprocket so a special rear sprocket would be the solution!
What did it set you back?
lol its a rocket on 3rd gear!
it will sit on 70Km/h at 4000rpm which isn't too bad, got a RK 428 Heavy duty chain which is alot better than the stock 420
