Re: 800rmk carb tuning

Hello James,
My Polaris dealer just set up my 800RMK Saturday. I'm picking it up tomorrow. I ride from 4,000' to 6500' ele. They were nice enough to change the jetting, and the clutch weights in the shop as part of their dealer prep. (They installed a 144" track for me too.) Didn't your dealer set your sled up? I think I'll wait until I've got a few "break-in" miles on it before I mess with mine. You might want to order the Service Manual through your dealer. It covers everything.
Happy trails,
Fred(Oregon rider)

Re: 800rmk carb tuning

fred,
thanks for the reply; yes the dealer did set the sled up for me but I seem to be having considerably more problems with my carbs that both my neighbor or my wife!!!!
we all have the 800 rmk and mine is the only one that runs extremely rich on the bottom and low mid range. We all ride together and it seems that my sled is always rich compared to theirs. I am still working on it, I guess this week I'll take the carbs apart and check to see if there's a peice of trash in them somewhere. the only other thing that i could think of is that maybe the choke system is misadjusted.the sled runs good (kind of) when it is about -5 deg.F.
but antyhing warmer and its a dog. I cant find anything that describes the technical poeration of the parts on the flatslides that are on the 800rmk.
I'm looking to find out roughly how sensitive the gas screw is on thes carb.
your help is apprecited.
thanks.

Re: 800rmk carb tuning

I wasn't going to respond because the Polaris service manual Vol. IV that I purchased for my 99 RMK doesn't cover specifically Y2K sleds or the 800 RMK but I remembered reading that an out of index crankshaft can cause difficult carburetor calibration and fouling. So don't overlook this. The service manual covers carburetion, clutching, theory, troubleshooting and everything else. Very informative and well worth the 50 bucks I paid.

Re: 800rmk carb tuning

Hey! I should have mentioned the changes that were made on my jetting. 300 and 320 (The 320 on the mag side.) The clutch weights were changed to 60 gram weights. I "REALLY" like the power. Also, I've been searching for a dealer that had the shop manual in stock, and found one. Extreme Polaris in Colorado. There toll free number is 1-888-494-0997. Ask for Rachelle in the parts department.
Happy trails,
Fred

Re: 800rmk carb tuning

I wanted to thank all who helped me!!!
It turned out to be a combination of things.
but after a few weeks and a few rides, All seems
well,,, I had to put a hot seat clutch kit in the sled and
also had to drop pilots 3 sizes, mains are down 4 sizes,
and needles dropped 1 notch.
I also had to drop gearing 1 tooth on the top and add one to the
bottom.
All I can say now is that I'll see you at the top guys!!!!!
THANKS FOR THE HELP,, IT WAS ALL APPRECIATED.
