I have been rebuilding an 81 gs550l that I have had since I was 17. i swapped out the front forks and rims for those of a 91 gsxr. the swing arm came from a gs750. Everything is working perfectly except the chain alignment. My first thoughts were to use an offset front sprocket then make up any difference by shaving the sprocket carrier on the rear wheel, but unfortunately my clutch mechanism is too bulky for an offset front sprocket. I cant get enough by shaving the carrier alone. any advice?
