[QUOTE="rmc_olderthandirt, post: 1159562, member: 68872"] Do you use the same oil and mix ratio as your brother-in-law? Do you both weigh the same? Do you shift at the same point, push the bike equally hard? Are you both running the exact same sparkplug? Do you clean out and repack your silencer as often as he does? A "no" to any of those, and probably some questions I didn't think to ask will make the results incomparable. A two stroke has oil in the gas. This oil usually doesn't get burned completely and is expelled out the exhaust. When it leaves the cylinder it might be in a vapor but as the gases cool in the pipe the oil can condense out and end up collecting in the pipe and silencer. Making the engine work harder, either from carrying a heavier load or simply pushing it harder will increase the temperature of the cylinder and exhaust system. A hotter pipe will tend to keep the oil as a vapor and expel it instead of letting it condense. A hotter spark plug will burn the oil deposits off more easily, making the bike more crisp. Taking your silencer off, cleaning it out and replacing the oil soaked packing with fresh packing will make a big difference, for a while. It will most likely get saturated again but for a while it will be better. Rod [/QUOTE]
