Hoist,
You just described why my buddy Stoneman got hosed by the Hollywood bike shop he started out with. They were trying to stuff 5 gears into his old 4 speed case ( one that did not accept a trap door) They had the shafts at a machine shop doing God only knows what to em. The EVO 5's with belts had a long enough main shaft, but because of the gear jam issue where the counter shaft would try to climb over the main shaft I wanted a TC 5. The older EVO 5's had a thinner trap door which would warp after awhile due to the the issue I just mentioned. In case you didn't see elsewhere, FR8TRN came through with a brand new never used 06 complete 5 out of his watermelon he took delivery of with a 6. Already got the parts in hand for a price only a righteous site bro like FR8TRN would have shipped em to me for. My only issue is the larger main shaft, bearing, seal and retaining ring which is why we need to have the Sputhe case machined. No problem there that I can see. As I said my buddy Jerry and I dry fit the who trans together yesterday and the only issue was that bearing. The TC 5 main shaft is plenty long enough for the trans belt pulley. We are going with a late model narrow belt so Stoneman can put a 180 tire on the back. And YES, I wish I'd gotten involved here before he started muckin around with a classic, rare and cool bike. I'd have helped him restore it and sell it in stock condition if he wanted a more modern ride. Shame to have messed around with it like this, but I came in on it too late. This bike came from the MoCo with a Evo motor, 4-speed trans (with kick start) and chain drive. It is a 1984 FXWG. One of very few Evo's with a 4 speed and chain drive and one of even fewer with the factory kicker. 83,84,85 had a handful of odd bikes like this as the MoCo went from Shovelhead to Evo. FYI, if anyone ever tells you there were no 83 Evo's They're WRONG. The MoCo had some factory mules out on the road testing the to be released in 84 EVO motors. Don't know why cause they don't do it as a rule, but they sold em when they were done with em. So there's so very odd 83's out there with EVO motors.
