My '93 XJ600 shifts and rides fine since I did a miracle repair on it (as in I had no idea what I was really doing).
I have a new problem though. It fires up first or second time, no problem, I give it time to warm up, moving the choke as needed so that it runs with no choke. Gear up and take off across town, stop at the gas station to get a soda and stop at a friend's store and then head back home. That's when the problem starts.
After I've been on the road for 5-10 minutes, I pull the clutch to start down shifting, but the bike starts screaming. Literally, 5-6k RPM's. If I'm at a light, I put it in first, let the clutch out until it grabs and just stand on it to keep it from going anywhere; the RPM's drop to 700-800. Take off no problems, go to make the left turn into my neighborhood, pull the clutch and it starts screaming again.
TL;DR.... After 5-10 minutes of riding, whenever it's either sitting in neutral or the clutch is completely engaged in gear, the RPM's go well past 5,000 and it doesn't come back down until I let the clutch out or turn it off.
Any ideas?? I'm at a complete loss, especially since this doesn't happen right away when the bike is started, only after going a few miles down the road.
EDIT: the other thing that worries me about this is obviously if it's doing this while I'm downshifting or sitting still, as you could imagine, it does it when I'm trying to get to speed and going through gears, and it sounds like it is just smacking the s**t out of itself when it shifts. I don't want to break anything on this bike, but I feel like I am not mechanically inclined enough to even attempt fixing whatever this is.
