Ok, this is a bit odd because there were no warning signs that this was getting ready to happen. I had been using the Rotella oil that everyone had recommended and shifting was good. Pronounced, but good. I decided to change out my oil to Valvoline 20-50 motorcycle oil and man, what a difference it made. The shifts were smooth as can be and it felt like a brand new bike. I was riding this morning and no problems at all. She felt great. I pulled into a parking lot and she sat for about an hour. I came back out and got on the road, tried to shift and nada. Couldn't get her out of first gear. Got off the bike, put it on the center stand and tried to change gears by hand and the shifter just isn't wanting to go up. Verified the clutch is disengaging by seeing if the rear tire stops spinning. It does. Ideas? Surely it can't be gear failure because it seems like I would have had some warning before something like that would happen. I'm at a loss.
