I have just installed a new clutch and cable in my 1985 R 80.I took the bike for a short(15Miles) test run and and noticed that once the bike warms up,after a few miles,2nd and 3rd gear scratch when up-shifting.No scratching in the higher,4th and 5th.No scratching when downshifting.I am running 85W 140 mineral based gear oil with a moly additive in the tranny.I had the problem also before changing clutch and cable but was hoping that the new components would cure the problem.Not so.
Since I have had this bike,since march, I have only put about a 1000 miles on it and have changed the fluid three times(because I removed the tranny twice) never any shavings on the drainplug, no notchyness detected in the rear wheel when spinning in neutral.So, because of the Mfg. year (Oct."84) I am wondering if we have the circlip-issue or am I running just the wrong gear oil for this climate. I live in Alabama where it is very toasty.When I first take off(gear oil cold and thick) no problem,the bike warms up,oil heats up and gets "thinner" and we have the scratching gear-shifts.Any thoughts?
