Thank you. It was a huge effort with lots of improvements over the years. The nice part about making most of the components is that you can improve them as necessary. The bad part is the time.
I consider the gear box and the clutch to be the best investment on the bike. The box shifts sweetly and the clutch is perfect. I have run against Vincents with stock box and clutch, but unfortunately they are just too trouble prone. I have had no DNF's and no DNS's, which in great part is due to the clutch and gear box.
