How do I get the boost to ride lighter

[shattuck]

What about the lynx 3” track? Its already cut down. Is the lynx 3” or 3.5” pitch?

Tony do you have boost and 9r clutch kits in the works?

Im still working on the P22 setup.

I ran a P85 on my boost again today. All I can say is all smiles.

If it works, it works.
What’s the benefit the bottom end crisper?
Is taper the same?

So I’m wondering if an electric start kit for a matryx na would fit on my boost? Than I have the p85 and wish I had electric start anyway...

Yes and yes.

Tony, hoping you figure stock clutch because I have a 9r coming also. Didn't really want to buy 2 new clutches

With the P22 having a larger diameter center bearing than the P85 shaft, the belt may engage higher in the primary with the new clutch, This will have it start out in a higher gear and with no boost and heavier weights, that is a struggle. This, plus the lower compression pistons and restriction to the airflow will make it boggy. The best way to deal with this is gear down and have clutch weights with a light heel to let the rpms build before the load builds. Polaris should come up with a larger diameter secondary clutch for this application. The turbo 9R should be better when it comes to market.

Toby got the air flow fixed and dropped boost temps 30*. Tractor boot and a BD frogskin filter. I’ve been running it.

Finally got in my first mountain trip on the 165 2.75" boost, the sled is totally stock including clutching it has about 700 miles on it and I feel it is lacking in throttle response also. Went to Revy and had excellent 24-36" fresh powder for 1 day and heavier snow another. I'm 58 years old, 5'8" and weigh about 160 lbs. My last 5 sleds have been axys 163's, 3-800's and 2-850's all with with low bars, Silber turbos, Raptor shocks, 36" trencher front ends, and offset spindles where I rode with various widths from 34" to 36", I also rode with and without the swaybar at times. Riding with the 34" front and no swaybar made it a challenge to not over-ride the sled, at times it would move quicker than I could react to so I went back to the swaybar. I found the boost to feel very heavy on the front end and the ski shocks felt very firm even with the clickers backed right off. I felt it took more effort to get the sled on edge than my previous setups. I did remove the link on the swaybar about 1/4 of the way into the day, increased the preload on the center shock, and played with clicker settings. That did help but it still has a way to go before I'll be happy with it. One of the guys had a 2022 165 expert Doo and when I rode it it felt like it had power steering compared to my heavy steering boost, it took less effort to initiate a downhill turn and to get on edge. I'm a Polaris guy so I would like to reduce the heavy feeling and get this boost to react with less effort than it currently takes. I'm not into doing all the fancy tricks, I just want to fine tune this sled to make it easier to ride in the trees by making it feel lighter on the front and require less effort to maneuver. I also want to improve the bottom end response so I'm looking for some clutching to make it rippier without giving up on the top end. I plan on installing a Khaos limiter strap. What other suggestions aside from dropping my age from 58 to 28 or suddenly becoming 6'4" tall do you folks have? Wish I could turn back time but it isn't an option. LOL!!!!

Does it feel loaded up on the bottom end? Are you fauling plugs on start up? I had to replace a coil it made a huge difference.

Boost was light as a feather today. Finally got it stuck. Branch locked my brake. Thought i could go because i have boost and a tapered tunnel. What a mistake that was. Would have took 1 minute to tromp front out. Stuck for 45 minutes. Montana just got dumped on. Buddy broke his throttle and we called it an early day. Going next 2 days.

My khaos boost feels super light on the skis. Tony is definately onto something on body positioning. makes it really easy to move forward and inch or so. I've learned after a few years on a cut axys, just stand mid board and you sort of just float the front everywhere and steer with your body, not the bars.

I also have a composit m770 on it. When you whack the gas it floats the front end.

I’ve only fouled 1 plug and that was 400 miles ago. It just runs rich on the bottom. You can feel it in the throttle, just isn’t crisp.

It says bmp on the side in his instagram post.

good instructions on shock set up

Mine felt like it was running rich on the bottom end. It ended up being a bad coil

Since I'm in my sixty's; I put the front A arm in the lower mounting hole for a lighter steering feel. Feet rearward also helps. I think the new 15" lynx 3” track could be the ticket. Hopefully someone comes out with better clutching out of the hole but may need to gear down.

A-Arms have adjustment holes??
