When Dave Moss originally got his hands on OTT's project Suzuki GSX-R750 it showed signs of being a stunt bike in a previous life. Eager to bring this bike back to its track glory, Moss has been picking away at things that need to be replaced. This time around it's the ridiculously large rear sprocket, which is great for wheelies, but rubbish for the track. Follow along in part 1 and part 2 as Moss takes you step by step for the install.
