So I bought an 87 that was in great shape last year from a guy cheap who didnt know what he had (or did he) Spent a bunch of time (and money) getting her back into shape. Basically just cleaning it up, new tires, chain, sprockets, rebuilt calipers, new fluids, etc. Basically a total restoration. But I guess I should have concentrated on the motor first. When I rode it last year, sounded like it had a misfire but I just thought it was becasue the carbs were gummed up, bad plugs etc from sitting so long. So I disasembeled the carbs, soaked them, cleaned them, and put them back together. Installed new plugs, and a new battery and attempted to fire it up. Runs great on the left 2 cylinders, the third is warm and the right one is ice cold. There is spark on those 2 cylinders, and it is getting fuel. Actually I think it is getting too much fuel becasue if I pull the plugs and crank it over, fuel shoots out to the cieling. So if I have spark, air and fuel, why is that cylinder not firing? Also I noticed that while I had the header off, looking inside the exhaust port, that one of the valves looked a little oily (not wet to the touch, just looked different) and the others were completely dry with carbon. Dont know if this has anything to do with my problem. Could it be that the carbs on that cylinder are just dumping too much gas? When I took the carbs off to clean them, there was fuel just laying inside that intake track of that right cylinder. But I took the carbs apart and put them back together and they seem to be working ok. I am at a loss.
