Well, I don't know what exactly happened, but in lieu of the fact the the bottom of the transmission and mufflers are clean, I must not have put any oil in it. I may have had the drain plug in loosely, and it fell out.
This all would have taken place last March.
Saturday, I went to ride across town to see my sister. I got on the belt-way just a few miles from my house, and put it in 5th, where it stayed for some 20+ miles at @65mph. When I got off the highway, I immediately knew something was wrong. I was hearing strange noises that varied with road speed, and the clutch lever wasn't really doing it's thing, and it was REALLY hard upshifting and down.
I thought it was the clutch, because that was the last thing I was working on. So I thought I could limp to my sisters house where I could leave it.
LOL! That box must have been red-hot! I got within 5 blocks of her street when the rear wheel locked up at about 30mph. I had already prepared to turn on my 4-ways, and I have my nice flashing red LED's on my brake light, so I wasn't rear-ended!
I was right next to a church parking lot entrance (on the other side of the street, though), and I could not find a shift-spot that would allow the bike to be pushed. It was connected to the engine, and you had to overcome compression to push it!
Finally a fellow in the line of cars behind me got out and helped me get it out of the way.
I parked it on it's sidestand while I called my sister. Then I started looking for something to put under the stand on this hot, sunny day on this fresh new asphalt.
Well, behind their activity building was a nice big old slab of brand new concrete! And the bike wouldn't be seen from the street! So I went back, and discovered that it could be pushed easily, but only while pulling in the clutch. I guess the clutch got a little warm, too.
My GPS says I went a total of 30.3 miles.
I was REAL damn lucky it didn't lock up on me at speed on the highway amongst all the other fast moving traffic. I'd probably be dead right now.
