Picked up this 1974 R90/6 yesterday. It last ran in 1998 and sat outside under a tarp for at least the last couple of years. I haven't decided yet if I will resurrect it or will use it as a parts donor for the other two 1974's I have (R90, R75). My inclination is to maybe get it running but if that happens I'll be inclined rehabilitate it. The picture probably shows it better than it actually is. The gas tank, which attracted me to it in the first place, is in good condition. The engine is not frozen. Carbs need a total rebuild. Tranny was supposedly working fine when parked (with the speedo drive cable not inserted) but I haven't checked the fluid/drain plug condition yet. True mileage unknown as the odo doesn't work according to the PO. All in all a fairly complete bike that I'm excited to have in the "stable." The wife thinks it's cute but, of course, she also asks "how many bikes can you ride at one time?"
