I want to increase ski pressure. What are the trade offs when I shorten my limiter strap by one hole?

a tiny bet less weight transfer, honestly I didn't notice a difference in that, though. It's worth going up on hole for the increase in ski pressure. This sled transfers the weight way too much with the stock limiter strap location, especially with studs.

Thanks for the reply. Just don't want to loose any acceleration.

With this setup you can use the rear scissor stops to control weight transfer, blocks forward for riding, down for lake racing, takes 1 minute to change, unlike that limiter strap, which sucks to adjust.

You forgot to tell him that sucking up the limiter reduces travel and ride quality. Regardless of brand, the first thing I would do to increase ski pressure is increase the preload on the front shocks. Second thing I'd do is move the blocks to keep the skis down under acceleration or power on cornering, shorter coupling. Third, I'd reduce the preload on the front track shock. Fourth, I'd put longer carbides on. The limiter change is the last thing I'd do, unless I was a dedicated drag racer only concerned with going straight.

what he said^^^^^^^

Are you running a single edge ski or dual? I went with the Sno-Cross single runner ski from Polaris with a 6" carbide, tightened the limiter stap one notch with scissor block middle position and 3 turns tight on stock front ski spring position and sled is handling great.

I haven't tried spring changes, but I did go with the sno-x skis as well... Turns too well, especially with the bars forward.

I've been through it all!!! It's at the dealer right now.... Bet you're just dying to get into the protected forum and find out?

LMAO! yay2.gif
Yeah....that's it.... wink.gif

I can hear it already.... :div20:

fyoushun: "Pssssst, did you know about that new dielectric super compression increaser? I got one...and boy does it make that Profusion RIP! I did 129 on the ol' dreamometer" matt: "Yeah, the Polaris Engineers really did a bang up job on that. Increases compression by 13.069 % which equates to 6.935 hp increase at the track" Matt worshiper: "REALLY? You guys are so knowledgable, I wish I could be like you! Now, if I could just afford to get rid of my 73 colt...."

Sledaholic does it really corner good now? Mine pushes bad in the corners! I don't mind spending the money on new skis as long as it works.
Thanks in advance Jack

ski doo skis 0 push. actualy had to back off spring pressure.
Pol900
put on a set of Simmons flex pros, had to turn the ski preassure 15 turns softer.well worth the money

heres whats going on with mine, with a tad of throttle, the front end comes up just high enough to extend the front shocks to limit, renedering skiis useless in the air. this wipes out one and four of the typical fixes you stated. center already bottoms easily, so that knocks out fix #3. fix #2 ruins x-fer with no compromise. My thought, suck up limiter 1/2 hole(new hole), soften ski shock preload due to stiffness, tighten frss blocks for more coupling, attempt to shave or new hole rrss blocks for less coupling(more x-fer). I still have no sit in @ 200 miles. Someone stuff one tons in there? FYI, when skiis are down hard, it steers too aggressive. softening of springs should help.
I have slt's on it.

Love it... "tad" of throttle? Don't take much does it?

frss s/b tight?

No offense... Where's you rear spring and do you have fatboy springs or perhaps need them? Maybe just a click tighter? Skid seems different to me in a lot of ways, seems pushed back and flat-er.... It's taken every hit I've given it, though a couple left me wondering if it was rider error or I need an adjustment.
