Final drive oil change

So since I put the new final drive on the 2002 I really only took a few short trips to get the feel of the bike. I did notice when I got off the throttle and it started to decelerate that there seemed to be a little whine in the rear. As soon as you give it just a little throttle it goes away. I pulled the inspection plug out tonight and didn't feel any fluid so I pulled the plug and drained what was there and pumped in new Valvoline Synthetic Blend 80W90 gear oil. I plan on riding to work in the morning for the 1st time on it, so I'm hoping that helps. I'll report back in the morning.

if there is a little whine in the rear, you could always add some cheese in the front

Normally a rear end whine is from setting the backlash too loose. Idk if it's even adjustable on our bikes...

When filling the rear drive oil you should add some oil then rotate the tire. The oil will disappear allowing you to add more oil. Repeat the process until the rear drive is full of oil.

I'll check it again when I get home, seems like it's probably normal noise. I didn't hear it that much on my 94 because the exhuast was louder.

Mine is aluminum, but very soft and very thin. Would break very easily. I put a piece of blue paper/cloth shop towel between the plug and the wrench to keep from rounding off the corners, and just slightly snug it up. Bike should be on the centerstand or it will not get completely full. Put some rags under it. It is messy getting spilled gear oil off the rear wheel and tire.

I am a motorcyclist, NOT a biker.

I still have the old final drive and was wondering what to do with it. I'll probably pull that plug off in case I need it in the future. Not sure what to do with the rest of it other than scrapping it. The gear's shot so it's pretty much worthless from what I understand.
