[QUOTE="Rich Rohrich, post: 1438811, member: 16241"] 32:1 is the correct mix for the bike, putting less oil in the fuel will only wear things out quicker and won't make it smoke less. Start with the basics: [LIST=1] [*]Clean the insides of the pipe of any old carbon and oil. [*]Repack the silencer. [*]Fresh plug in the correct heat range. Lots of people stick too cold a plug in 125s and cause the issues you are describing. [*]Clean the ignition coil connections and make sure the system has good clean ground wires. [*]Check the compression and make sure the rings and piston aren't just worn out [/LIST] Once the bike is mechanically sound, then check the Two-Stroke forum here for tips on getting your jetting dialed in. With the correct oil and a sound engine properly jetted you can run the bike at 16:1 and still not have it smoke when it's run hard. Good luck and let us know how it goes. [/QUOTE]
