Just became a first time owner of an 1976 R90/6 with 24,000 miles. Purchased on Craigslist. It has not run for the past couple of years. PO said it had no spark at the plugs. Battery was shot (would not hold charge). I got it home on my trailer and had it running a day later with a jump from a good battery. It had a broken primary wire at the left coil. I made a short trip around the block and found a few issues. Clutch is balky and carbs need service. Since it has been sitting for so long I plan to inspect all the usual suspect items, all of which I have found written up here on this forum! It's a wealth of knowledge and info so thanks for all the help and advice in advance. I am looking forward to having a reliable vintage bike in a few months. Glad to be on board!
