***UPDATE*** I ordered a 9 tooth Comet jackshaft sprocket to try, however, the side pucks of the sprocket are narrower than the existing 10 tooth sprocket and would cause chain and TC belt alignment issues. So, I decided to replace the 50 tooth rear sprocket with a 60 tooth sprocket. Big difference in performance and I picked up approximately 250 engine RPMs. The mid-range improved markedly and the bike was a lot more fun to ride! I'm going to make some spacers and also give the 9 tooth jackshaft sprocket a try, also. Once I get some more time, I'll use a GPS and post some top end results.
