[QUOTE="2strokerfun, post: 1221437, member: 69719"] All the older bikes were supposed to be at or about 20:1. Using modern oils, however, 32:1 is safe and less costly. You may have to rejet a bit. If the previous owner(s) didn't rejet the bike, it will likely be jetted a bit rich. And 32:1 or 40:1 is actually richer than 20:1. First order of business is to take the carb apart and clean it and each jet in it very, very well. And make sure it has fresh air filter. When I picked up my old bike, it didn't even have an air filter on it. I was going to rebuild the engine anyway, or I wouldn't have even considered buying it. [/QUOTE]
