If you want me to tackle it, I can, but it would be a slow process and If I found a surprise, it might still find its way to Guenther.
and if I hadn't taken so long to post, I'd have beaten chip to the Guenther response, but he isn't local.
Anton Largiader and Tom Cutter would also be on my short list for gearbox builders.
Normally I'd do it myself too,I yanked it out the other day and thought about it but it needs the circlip mod and I wanted a longer Siebenrock or HPN 5th gear etc... The transmission in this bike is the only thing that has not been overhauled or redone. i was hoping to find somebody around here so there is no excuse to put it off.
