Jetting your bike properly is key for having fun in the Gunnison Basin. Your bike will make better power, use less gas, not foul plugs and lose the cloud and drool when carbuerating properly. CBTRA president Don Turk has the following advice to offer when jetting:

4 Strokes (stock) Summer Riding

For 6000 - 9500 ft drop the main jet 2-3 sizes, fuel screw 1 turn out.

For above 8500 ft all the time, drop main 3-4 sizes lower needle-raise clip 1step, 1 size smaller pilot, fuel screw 1 turn out.

For bikes with after market exhaust and air box lids removed start with dropping the main 2 sizes and 1 turn out on fuel screw.

2 Strokes (stock) Summer Riding

For 6000 - 9500 Drop main 3 sizes lower needle raise clip 2 steps, 1 size smaller pilot, air screw 1 1/2-2 turns out

For above 8500 all the time drop main 4 sizes, use next step leaner needle on top clip, 2 sizes smaller pilot, air screw 1 1/2 turns out.

These spec are for most modern stock bikes in warm weather. cooler weather and after market products will require less of a reduction in jet sizes and plug checks. Brown plug GOOD,lack plug to rich. grey or white to lean. Suzuki drz 400 we/ air box lid removed and a pipe, change fuel screw to 1 turn out only. Ktm 2 strokes seem to run rich to begin with a sea level.

If it's your first time riding at these elevations, plan on spending some time rejeting your bike when you get here. Every bike's different--be ready to switch jets, check your plug and so on until you get it right.
