Greetings to all of you. I'm a new forum member; having joined to learn of and share operating experiences about the R65.
I just purchased a 1983 R65LS. Its former owner bought it new, rode two tours - Nova Scotia's Cabot Trail & toured White River Junction, VT - then "quit riding while still ahead". He put it on the centerstand in a heated garage, oiled the cylinders, removed gas, battery and covered it. After it had "slept for 28 years", he decided that he was never going to ride it again.
Outwardly, the bike doesn't seem to have aged except for the slightest hint (tiny) of rust on the tank side. Inwardly, the steering head bearing grease has hardened/separated and the clutch wouldn't disengage. The brake fluid within the master cylinder turned to a dark amber color.
The carburetor fuel needle jets were varnished and the left float bowl was full of green oil (probably leaked out from cylinder during initial storage preparation). I suspect the fuel petcock strainer is probably varnished too.
I'll be reading forum posts to learn about this bike and will share experiences (mostly technical) as they're learned. Bradley
