loosen your rear track shock tighten the front track shock and get back to us

Why do you want it to "stand up " ?

The Khaos rails are a small part of the Khaos package, not sure rails by themselves are going to do much. You need at least a Khaos length front shock and new longer limiter strap. If that isn't enough, add the Khaos Rear Track Spring, it is softer than the Pro. Your gearing is plenty low, especially if your at lower elevation.
The drivers for the 3" track are 3" pitch, the driver for the 2.6" is 2.86. I didn't have good luck with using 3" pitch driver on a 2.86 pitch track. I definitely had some binding issues. If it's working for you run with it.

Thx for the info. I did put the longer fox shocks and limiter strap my clutching seem fine and the 2.6 track I put on is a composite track with the 3 “ pitch. I was hoping some lower gearing may help me out

I was just wondering why Not trying to beat anyone up .

Ok so can anyone tell which gears are lower than what I have right now or any other recommendations?

The factory 2.6 inch track has higher gearing than the 3 inch. Higher gearing won't help get the front end up. There is a Kurts gear down kit for $600. I'm pretty sure that will help get the front end up!

I went with a 24tooth top gear when I put the TKI belt drive on my khaos 3in chain drive. I top out at 65-70mph. Stock is 2.32:1 and I'm now 2.42:1.

I don't think it helped lift the front end at all. My 165 Alpha will lift the skis way more than my 156 Khaos.
My buddies Matryx Khaos 156 QD2 lifts the skis much better than my Axys Khaos.

Maybe a more aggressive clutch kit that will shift up faster, creating quicker track speed will help?

With a 19 tooth top gear, I think the biggest you can go up to is a 46 tooth bottom gear. Any bigger and I believe you have to get a longer chain.
There is a thread on axys gearing.

 

[osiecki2]

do you guys think if i went to a bigger 46 lower gear i would loose track speed and it would actually be worse?

 

[summ8rmk]

I went lower for 2 reasons,
1. slow me down on the trail, 3in tracks don't last long at 70mph.
2. Lower belt temps playing in the trees.
Also with the thought of less load while climbing should allow the clutches to shift higher? I may be wrong, but I haven't seen any negative performance other than on trail.

My Pro has 19/46 gearing, and I love it. Granted, it came to me that way, so I can't compare to stock gearing. Also, it's a 163. I doubt you'd lose track speed at all on a 163, but good chance you would on a 155 in deep snow. My experience gearing down my old sled was that the off-idle and low-speed feel were the biggest improvements; it lets you use the low and mid-range power more effectively. It also depends on what elevation you typically ride at. The higher you go, the more you want to gear down because the engine doesn't have the power to shift the clutches out far enough. Anyway, gearing down has lots of benefits, but definitely not a one-size-fits-all. Pretty sure the 46 gear is the biggest that'll fit in the case, but that may require a longer chain.

awesome thx! i think i will order the 46 and give it a go!!

FYI, ur speedo will be off, on the highside 5%+ also, fuel mileage will drop.
Don't be shocked if you see 4 MPG on the deeper days.

Sorry but you will not have better result by changing the gearing. I think maybe you will see better result with a proper clutch kit.

add some horsepower........that will lift the skis
