It's an 84, with 160,000km on the clock. It's Mark's bike and he asked me to go over it and fix anything that needed fixing. I almost got it back to road worthy/safe condition, took it out for a test ride and found that shifting up wasn't bad, not great, but did work, but downshifting was and real issue. 2nd had been done some km ago and Mark says it hasn't shifted right since then, but he lived with it. Linkages were an issue but I fixed that and installation is on the marks. The knuckle behind the stator cover is in the up position, so we ripped into the clutch. Without the clutch nut installed it will shift by hand when turning the back wheel, but if we finger tighten the nut, shifting is hard to do if at all. I have an idea what maybe the issue, but I don't want to expose such an idea and cloud out the REAL thoughts coming from those who know.
So help us out here, get those brain juices running and offer your input. The winner gets to bring coffee on the next visit.
