I’ve got a newly rebuilt VBB with a Pinasco 177, full circle crank, etc… Finally got it running last night and it sounds great. But I’m having the following issues:

With the engine off, clutch engaged and in gear; I can roll forward with no issue, but when I push backward the engine tries to kick over.

With the engine on, bike in neutral; I engage the clutch (and hear/feel it engage), shift to 1st, the bike lurches and dies.

When I’m in neutral, I can roll forward and backward no problem, whether the bike is running or not.

Clutch is rebuilt and adjusted in pretty tight. The part that’s throwing me off is the fact that I can’t roll backward in gear with clutch pulled in.

Does this seem like a clutch related issue, or could it be the shifter or primary gear?
