I am in the process of restoring a 1974 850 Commando. The bike only has 2000. original miles on it but the previous owner left it in a humid leaky shed for about 12 years and never started it. It is a cosmetic mess but the cylinders and heads look great as well as the inner primary. I am restoring the bike to original and I was wondering if there is any reason to replace the crankshaft bearings if the existing ones look good. If you think I should replace them what type and from who do I get them??? Should I replace the rods while I have it apart??? I plan to replace all engine seals. I want it to be a nice looking rider and not a show bike. I don't plan on hot rodding it around or doing any special engine mods except for maybe a Mukini and Boyer. Thanks fo any suggestions.
