Just a heads up but there's an R65 Owners Manual available in the R65 Technical FAQ/Procedures section that will answer many periodic maintenance questions.
Besides what you've mentioned, there's the driveshaft gear oil, air filter, tire pressures, brake fluid, brake pad and shoe wear, steering head bearings, swing arm bearing checks and grease. Compression and leakdown checks may also come into play.
Our R65s are all over 30+ years. Regular fettling is the name of the game.
Might you add to a sig line the model year of your bike? That, or mention same in your post. As there are a few differences through the production run, it will assist others in providing you with correct information. Thanks for that.
