Ray,

Any suggestions on rejetting the MR175 to run in Colorado? I currently live at approximately 1000" ASL. Would like to take the MR out ride in CO this fall at levels of 6000-9000 ASL
Thanks

IJ

At the higher altitudes I'd probably run a 45 pilot / 115 main / 3.5 slide above 75F, and 48P / 118M / 3.5 below 75, with the needle at #2 or #3. If it goes below 55F I'd throw the stock 3.0 slide back in to see what difference it made.
