Jetting. HELP.

[NDFARMER95]

Got my cousin talked into going west with us and he's got a 07 600 h.o. rmk 144. Wondering what the best overall jetting is for 6-8000' or if polaris's specs work good?? Thanks, Kody.

I run 280s in my 06 600ho 144 in the Black Hills, West Yellowstone, and Island Park. It works just fine from 6000-9000ft.

Or he could install the HOLTZMAN ATAAC, and leave the jetting he has.

After that the ATAAC will compensate for altitude and temp.

Installed that on (5) carbed EDGE's, improved throttle response and mileage.

Set ours up initially for 1200' (U.P. Michigan) and trailer-ed all of our sleds to WEST Yellowstone, ATAAC performed flawlessly on all our sleds.

E-Z less than a (1) hour install and approx $ 245

270 280 are safe, 40 or 45 pilots will clean up low end, fuel screw 1 turn out. There is more but this will be close. Have fun
