I got the spark plug tool in and it did the job. The one I received is 4 3/4 inches. The one I had was 4 inches. I'm supposing that it was for a 350 or something because I did receive some 350 parts from the guy from whom I bought the engines and parts buckets.
I also bought an exhaust and muffler for the 500, as well as a tank for the 550 from Bill Benton today. The tank is in really good condition (no rust whatsoever on the inside) and has a gas cap on it. The paint is in such good shape that I almost hesitate to remove it and repaint. But there are a few small scratches on it and that's probably going to be the tank that goes on the 550 so I have other ideas than red for it.
I also put a first coat of trial paint on the tank for the 550 but it showed me that there are still 2 small areas that I'm not 100% pleased with. So that coat of paint is coming off and I'm going to re-work those 2 areas to get them right before the tank goes on the bike.
