GoldDigger and Lonewolfx;
Put the bike on the center stand and get hold of the bottom of the wheel and try to move it side to side if you get movement the rear bearings a going south.
GoldDigger: with 127,000 on the wing it could be the rear bearings are going out. That's about the mile I had on mine when they went, but I also had pulled a trail close to 30,000 miles at least.
If you are going to change the final drive and you should.
Get some SAE 80W-85-90 gear oil in the plastic quart bottle from NAPA. It has a pointed cap on it. Also get about 18 inches of rubber surgical tubing from the hardware store that will fit over the point on the bottle cap.
1.Drain the oil from the final drive.
2.on the back side of the Axle on the final drive and just above the axle is a I believe it's 17MM plug. that's the filler plug, remove it. ** It is aluminum be carefully not to round the 17 MM head off.**
3. Cut the tip off the point on the gear oil cap and push the tubing on as far as it will go.
Put the other end in the filler hole., invert the bottle and raise it above the axle level, and squeeze. Fill till the oil starts to come out of the hole.
4. Be very care not to over tighten the plug. See ** above.
Hope this helps you out.
