Stock RPMs

[veritascs]

Hey Guys, don't know much about clutching but looking for your opinions.

I pull 8250 RPMs on the trail at around 8000 feet. Then under load at 9400 feet, a few feet of condensed powder, I was pulling 7700 RPMs. Does this sound normal or I should I be able to pull 8000 RPMs at this elevation? Sled is 100% stock, 800 PRO-RMK 163" track.

Your stock clutching and gearing is most likely set for normal conditions at elevations of 6000-9000ft. I would say your sled is operating normal under the conditions mentioned. If you often ride at 8000 to 10000ft especially in deep powder, I would lower the gearing for sure, and maybe go to next lighter weights if needed to pull 8000-8100 under load.

I would also change the helix. Talk to Carls

I have a 12 Assault and pull 8200 on the trail, loaded I pull 8000-8100 stock 62 weights and I weigh around 170 fully geared. sled is 100% stock

I see this get thrown out a lot. I am from Bozeman also and have rode a Carl's Clutched 800 RMK 163. To tell you the truth, I didn't think it was worth the money spent. I am thinking the conditions the Carl's Cycle team rides in may be different than what we ride in SW MT. I put a blk/purple secondary spring in my 155 and run 60 gram Polaris weights. I typically am pulling around 7900-8100 rpms, regardless of whether it is on the trail, or in deeper snow. I was with a buddy one day when he had a infrared temp gun and the one time I checked my clutches after a prolonged session of riding my primary was 165 degrees. I have no idea what that means. I would say I averaged about 800-900 miles per belt, no vents. I guess a guy can always strive for lower temps and better performance, but mine sure seems to run good.

I'm guessing that you're a light guy? If mine ran like that stock, I wouldn't touch it either! AKSNOWRIDER gets away with a stock helix in his. Me being about 50#'s heavier, my rpm would vary +/- 300 rpm on a hill. Dropping to a 40* finish angle, now I hold +/- 50rpm. I've run across this a lot. Just something you deal with as a heavier guy.

I am probably 200-205 all geared up. I used AK's set-up to help me with my dragon, his knowledge was invaluable. One thing I have definitely learned since then is there is no "perfect" set-up for the masses. Personal preference, weight, snow conditions, riding style, all play huge factors in what you think works and what doesn't.

I couldn't agree more. But, Don't make Mikey's head any bigger than it is already. He may be a sharp guy, but he is just a little tack! Kills me that I have to Mod my stuff to run even with his stocker. When I really wanna shut him up, I just turn my boy loose on my stuff as he weighs 50#'s less then Aksnow does and spanks him lol

Seriously, I look for a setup that works well in the largest range of conditions. Consistant day in and day out, and most forgivable. Get there, and I quit other than to change weights when we really go up high. Sounds like that is where you are at. Nice place to be.
