Bryan, I have an '85 650 as well. I find it very hard to shift just about any gears while the bike is not running and find it easier to engage gears while the bike is running and in motion. So I click it into neutral just before I stop - going real slow of course because I'm stopping. Even then sometimes I have to click back and forth before it engages. be sure the shift lever is secured real tight to the shaft with the 10 mm bolt and adjusted correctly. There's a rod with a 10 mm locking nut at either end you can adjust to raise the lever up or down to suit your foot position. Be sure that it isn't locked up. There should be a little play in there. I don't think it's your oil, Graham
