Hey all... I've got a 1980 XS400g that I've been restoring to running condition. This is my first bike so I'm kind of learning as I go.
I had the engine running perfect, but now I've run into a transmission problem...
A few days ago, I went to accelerate from a full stop on an incline, and a machine gun sound came from the transmission and I could feel first gear slipping. If I take off easy with minimal power, it won't happen - but if I try to accelerate hard, it will start slipping again.
Since I've had the bike, the gear shifts never felt super smooth, sometimes refusing to to fully shift into the next higher gear. I've adjusted the clutch at the engine and lever according to the manual, so I'm fairly sure the clutch is disengaging fully. Oil was changed recently with Yamalube.
Full Disclosure: I did lay it down once when I forgot to put the kickstand down.
The only visible damage was a slightly bent shift lever and a scratched mirror.
So I think my transmission is hosed. I've decided to look at this as a learning experience and try to fix it myself, so I was hoping someone could clue me in on what to look for when I get the engine cracked open.
Thanks!
