@@camsenduroworks374 my transmission shafts aren’t rotating fully even after I put the forks in

[@camsenduroworks374]

@@michaelhernandez8102That’s normal, it won’t move all the way freely until both cases are put together. You are looking for the shift drum to smoothly through all the gears.

Thanks! You made it a little easier. It seems my shift drum doesn’t rotate or move so I need to recheck how I put it all back in.

What would a missing second gear be? Worn shift fork or gear? It like bucks like it’s not catching so I usually just go 1 to 3 but want to fix it.

that’s the same way my 5th gear is on my bike, i took it to a shop and they think it’s just the gear that’s worn out or sheared off.
