Final Drive Oil Leak-Conclusion
So here is the conclusion for anyone following.Got a used drive,new wheel bearings,cleaned brake shoes with wire wheel,plenty of friction material left. When I tightened the axle nut to spec the tire would not turn! When I removed the axle the first time the nut was barely hand tight. Which I thought was weird. So I checked the spec again. Looked at part diagram and noticed there is supposed to be a spacer ( 64772-34201 SPACER, LH) that was not there? I looked at my pictures again and it was not there...just grease and gear oil? Ordered used axle with the spacer that was missing for 9.00 shipped at my door in 3 days. Same place I got the rear from. So thinking the guy I bought the bike from lost it when replacing the rear tire and just left the nut loose? All back together now tightened to spec.
Filled with Wally GL5 gear oil. Ran bike with rear tire off ground for 5 min. No leaks. Drained oil. No metal on magnet.
Refilled, rode bike 120 miles. No leaks,drive hot but now I can leave my hand on it. Old drive only 1-2 seconds.
Drained gear oil again. Clean,no shavings! Rode 140 miles same results. Will ride another 150 then if a ll good will put in mobil one. I also changed engine oil and filter put in Rotella T6.
The bike rides allot better. 55mph and it doesn't sound like its coming unglued. I brought it up to 70 and it's way smoother. Yes the engine revs but good enough for around town. My fuel mileage also went up. I was going 90-96 miles before hitting reserve. The last time it hit reserve at 84 miles! Now with the new/used drive I got 113 miles and 115 miles before hitting reserve! YAY, I guess that broken drive was dragging bad.
Thanks to all!
