Okay, I’ve got a Yamaha 1969 AT1.  When I bought it, it wasn’t running. Had no shifter or clutch cover. I stole a shifter off another parts bike, bought a cover on fleabay.Ive got it running, when I went to shift, nada. No satisfying click of the gears to be heard. Everytime I’d pull the clutch lever in, it would detach from the claw inside the clutch cover (which made me want to snap my crayons). initially I chalked it up as the clutch plates being stuck. Long story boring, cleaned the plates off, still wasn’t doing anything different regarding shifting. Then I did what I should have done in the first place. I looked to see what was happening near and behind the clutch when I attempted to shift. The little clutch shifter arm is bent or something, and after moving it where it should be, it shifts for about 3 or 4 times. After that it gets off-kilter.

help?  

You need to post video to youtube or vimeo and link here... same with photos. Video has always been this way. Photos have been broken for a while.

It sounds like you might be missing the washer and snap ring under the external shift lever on the left side?

My bad, here is the link.

Did you check for the washer and clip?

I live an hour away from the farm where my “bike shop” is, so I won’t be able to check until I’m back in a week or so.. hopefully that’s the culprit though.
