CE 2.5 on the Pro

[Vinnee]

Vinnee does your track ratchet braking down hill? That is the only time I have run into it on my Pro 163. I have to run the track tight to not have it happen. Didn't even know what it was until I made a post on SW about a clunky mechanical noise when braking down hill. Again, never under power and i run in wet Washington too.

Nope... Not a thing when breaking down hill! Just under full power and load... Clunk, clunk, clunk, clunk... sounds really bad!!

As far as rachetting goes... This has been a problem on my 163 Pro... running stock drivers. Like many on this forum, I was convinced that anti-rachet drivers were not necessary. In most snow conditions they aren't... However, here in Western Washington the snow gets extremely heavy very quick. In the right conditions (often) I deal with rachetting. Most commonly only happens when you really need power and can't let off! ... Seriously.. the condition that causes rachetting almost every time for me is when I come off of a surface and engage another surface with the full length of the track at once. Happens allot on hill climbs were there is a transition or bump that you jump (mid-climb) and then reengage the climb with the full length of the track... I have experimented with every possible track tension with no success. I have come to the conclusion that I need to install drivers.

These are the 2 conditions I experience ratcheting.(this is on a turbo sled)
I've tried running it very tight.

I agree, with 10 psi boost and the stock drivers at proper factory spec tension, ZERO issues with track racheting. Just make sure its Exactly at the factory tension issue.

And having swapped a camo ext 2.5 on every sled i've had, so far other than braking issues the stock track works very very well. So for now I'm running that. Just so darn good in the powder.

I think the stock Polaris track 163 in soft snow is a much better track and floats much better than the CE 2.5. I swapped track to CE 2.5 and drivers to avid for more clearance and didn't get good results in Idaho snow like I did with stock 5.1 so I switched back. Now in heavier, wetter snow it will shine and results will be different. Not worth the time or money in my opinion

It's nice to hear some opinions from people who say the CE isn't that much better than the stock 5.1. I'm trying to decide what I'm gonna run for a track next year. The design of the the 2 tracks seems at least "similar".

The upgrade is relatively cheap if you do it right out of the gate before you ride your stock track. Sell the stock one, buy a new CE from dealer of your choice or tracks USA and you've upgraded for under $300

PV.. I think many run the combos because of the added clearance...no involute drivers in 7 tooth..

I had forgotten about that, good point.

I see no problems running either... and the old theories of an involute driver being more efficient on a properly set-up and maintained track don't hold as much water as they used to... especially with the advent of single ply mountain tracks... I know that Jack likes them and Carls runs ONLY them... but there is "more than one way to bake a cake"

neither do i and the new ones seem to be quite good and a very large improvement over the older style. I guess my main point was, you still need to run proper track tension even with combos

IMO... the added clearance is a plus in many ways and I have plenty of miles on extro equipped sleds to love them...

i agree but what i don't have a strong opinion on is how much of an improvement it makes and if the effort, either with a complete d&r or with 7 tooth combo drivers, is worth it?? everyone has an opinion, i just wish there some solid, scientific data on the change in parasitic drag from each option

Have successfully installed (2) 2.5 CE's on the wifes 2011 155 and my 163 Pro with no issues (Fit)! I don't buy into the tunnel clearance robbing horsepower.... No matter how much clearance you have it seems that there will always be ice and snow caked into the tunnel and rear of the bulkhead leaving 1/4 inch of clearance between the tips of the track and back of bulkhead no matter the scenario. Unless of course your in the sugar....... Of course, this observation is simply from the land of the wet and heavy!!

and this would be one of these examples of when combos would undoubtedly be advantageous.

The Ice Age chaincase is only 5/8" down and about 3/8 back... I dont think that a suspension relocation in needed...

Not to get off topic, but I wonder if this allows you to use stock mounting location and you were to go ahead and do this + a 7 tooth driver if you would have room for a 3"

 

[whittaker727]

IceAge doesn't show their D&R on their site.

I'll see what I can dig up.

Any response from them Eric?

 

[Mountain Militia]

i disagree as i have said it multiple other threads. for the vast majority of non-turbo sleds, if you run proper track tension combos/extroverts are completely unnecessary.

pv

I agree you do not need the extroverts, but they do help you regain factory clearance and I felt like it went better IMHO.

Working on it buddy...

Hope to hear from Mike/Brock soon with pics/details/instructions.

 

[whittaker727]

Thanks! That has a whole new set of wheels turning in my head

I'm telling you guys, no mods are needed here. Trust me, I'm the king of mods. I lov modding the sled. But the Camo-X 2.5 will fit with stock chain case and drivers. There is enough clearance.

It does fit and will run fine, but you lose half you clearance and in the heavy spring snow and it will not evacuate snow as well. I have ran it without extroverts and modified chain case and with and runs way better with.

Hey Mountain Militia, thanks for your insight being that you have run it both ways.

This issue would come up with switching to almost any other desirable track from the stock tracks -- most after market tracks are 2.5" lugs. I've seen these Pro RMK sleds with both a Peak track and a Camo Extreme track installed. Both looked to have ample clearance and no snow evac issues is all I'm saying. The guy with the 2.5" Camo-X said the track worked awesome under the Pro and was more durable than the 5.1

 

[Reg2view]

What I'm guessing a number of us are waiting for - an Ascent version for the pro. That should spike some more comparisons...

The Ascent track is a version of the Peak track made by Camoplast for Yamaha in 162" length/ 3.0 pitch.

So just get a 155"/ 2.86 pitch Peak track for your Pro.

 

[hostile1]

I ran a 2.86 pitch 155 2.5 CE since new on my assault but when it got to spring time I had to switch to the stiffometer because I was "clogging" with snow and I even wraper the inside of my tunnel! The track works with all stock components but if you want better spring performance you will need to drop to 7tooth drivers and mod the chain case.
