I've got a 1983 BMW R80 RT. I saw the liner peeling a little and decided to try clearing out the old liner and applying a new one. A decision I regret as this liner is TOUGH! I tried acetone, the liner laughs at it. Now I'm trying MEK substitute and it's not much different. The entire time the tank has had drywall screws and bolts inside and I've been shaking it for about 5 minutes every other day. I started this process a month ago and unless the bolts have scraped an area, the liner looks unfazed.

Any tips for getting this liner out that don't involve slicing the tank in half?

I’m wrecking what little brain I have left over here. My 1983 R80 RT shows 120/90-18 which from what I’ve researched can go up to a 130/80-18.

I can’t find a rear tire in these sizes for the life of me. Plenty of fronts, but none for the rear. My top choice is the Bridgestone AX41S to give you an idea of what style I’m looking for. Any tips or suggestions are greatly appreciated.
