Thanks for the thorough reply. I drilled out the sides of the air box back in 1981, so that’s a done deal. I rebuilt this carb with new stock jets and set the float level, as well. The day I was riding was cooler than it has been, so maybe it’s running ... more »

Haven’t messed with it since the post, but from the reading I’ve done, I think starting with the air mixture screw would be good. I hope to get it out, soon, so I can ride it to get I warmed up and then do the adjustments.

Yes, the shift pawl and spring are the first thing I checked. I’m in the middle of the tear down now. I think it’s a shift fork that’s bent. Will know soon. Thanks!

Had to use relief cuts to make flat stickers work on a curved surface. Added numbers, and it looks pretty good.

Where did you buy your fork boots? Mine are incorrect for the 81.
