I wish a aftermarket would come out are a sleeve for the rear master cylinder.
That could work IF they gave you a reasonably large discount on the new bike. (i said reasonably)I have a friend here that works at a Kawasaki dealer and he said they won't work on anything older than 10 years old even if they sold it to you. I said what the deal with that he said it simple. It takes longer to work on old bikes and we want to sell you a new one.....
