Indy Specialty 9R conversion

[FreerideBrad]

I’m looking for some input, experiences, and suggestions. I currently ride 2020 850 155 chassis with a 163 track, has the SLP outlaw twins stage 2 kit, Kurt’s gear down, Ice Age elevate kit with khaos rails. I purchased this sled in this condition and have a little over a season on it. I’m absolutely loving the way this thing rides, but would like a little more grunt out of the bottom end in hopes to make it a little more rowdy. I typically ride in the trees and am leaning towards doing an Indy Specialty 9r conversion. I’ve had a few people tell me to keep it as it is, and just buy a 9R when they are selling holdovers. I just can’t bring myself to spend $17-22k on a sled.
My questions are: 1- Would this kit (or similar) work well with my Outlaw Twins?
2- Would there be sufficient gains to justify the expense of a big bore?

if/when you buy a big bore you lose 90-100% of the value. If that makes sense to you - do it.

I agreed with the other advice you received - buy a 9r when it’s in the budget.

9r for sure!

bored out and renicked cylinders are a catastrophic failure waiting to happen. i had two. Good power once tuned and clutched properly. i went through six monoblocks because thin skirts crack. it will happen no matter what piston you use.

Thank you for pointing that out. I know the BB kits can be a little problematic in terms of reliability, which is why I was planning to use Indy Specialty.

What would you recommend for improving low end torque? I feel like the clutching is pretty good, but I am far from competent in clutching beyond following instructions.

Looking at your list the sled it has great mods done. I really am not sure what more can be done. Maybe others will chime in with some goodies that may help.

All last season, We had 3 9r's in the group and 2 axys - Carl's 900's with tons of mods. (Tunnel cut, LW parts, clutching etc.

Really apples and oranges.

9r dominated them bone stock.

Response, trackspeed, handling

That was kind of my thought, too. Which is why I was leaning towards a BB kit. Rethinking that after your comments on them.
I rarely post or comment, but have read a lot of Polaris forums and even got pointed in the right direction when I couldn’t figure out why my sled would only run intermittently. Lots of good info here, which is what lead me to posting my question. A lot of knowledge and experience in this community.

That’s good to know. It’s funny getting information from real world experience rather than claims from aftermarket builders.

Which track? Possibly something there if you can match your track to snow conditions.

I’m a huge fan of Indy Specialty their work quality is amazing but if I was to do a 900 I would use Carls. If you are on a budget a well tuned 850 is hard to beat even though I have a 9R I don’t think the increased performance value is there for what they cost compared to a boost not to mention there are more then a few factory 9Rs out there that don’t run as good as 850s

I’ve never ridden a 9R, only the old 900 fusion. That’s why I’m asking these questions. I don’t mind spending the $3k for the upgrade, provided the torque is there. From the sounds of it, the reliability is no longer there, which is a turn off.

I am starting to think that I may just have to look into buying a 9R even if it is used. After this tread, I am starting to wonder if it’s going to be much of a leap from what I currently have. I would not change a thing about the ride set up on my current ride (probably a lot to do with the Fox shocks) other than I want a little more snap out of the bottom end.

The more I research this the more my head swims. Now I’m wondering if I should just put a turbo on it. Too bad I’m not a clutch guru. Lol

I’ve thought of this as well. The problem is; I’ve only spent a little over 1 full season on it and last years season in SW Idaho was marginal at best. So I could find that it has plenty of grunt at the bottom and I have been just spinning the track out without a lot of traction.
It has a 163 2.6ish Composit track. I’ve considered putting a 155” under it to give it the rowdy I’m looking for, I just haven’t gotten too far on that. I just can’t decide. Hell, after this season I might not want to change a thing. I feel like my area gets a lot of different types of snow from wet heavy powder to dry and fluffy, to hard pack. So choosing a track that fits a multitude of snow types is tough. Part of me thinks I should just deal with a rough trail ride on a 3” and enjoy the hook up in the powder.

The composit 2.6 is heavy and folds over without hooking up.

Only thing worse is a 275.

Thank you!
I have my old 2016 AXYS as a back up sled that my GF rides occasionally. Would it be worth swapping them? It has the stock series 6 on it. I have honestly thought the same thing you said about the paddles folding over.
To be honest, I don’t think she would even know the difference other than I was working on sleds all day.

Depends how worn the rubber is between the clips. Just a longevity thing.

The track will still have very little wheelie but will spool up quicker due to lower weight.

Alternately.
A 156x3 will really change the wheelie factor.

A camso 3.2 or X3 is a good choice.

(Tracksforless in MI is a good place to buy)

Thank you for your input. I think for now I’m going go with a 155/156 track. I actually found a Series 6 for $75 today and it’s in really good shape. Just need to see if I can find some rails or just order from Ice Age.
At the end of the day, I just want to put a Mohawk in my seat and I think this will be a starting point.

I have found some take-off Matryx Khaos rails close to me. To my understanding they will fit under my 2020, but they are apparently a similar or same profile as the AXYS Pro. If that is true, would I require an anti stab kit if I use khaos length shocks and limiter strap?

Likely the matryx rails are drilled for antistab all ready.

The tips are different.

22-23 khaos rails are close to axys rails.

24+ pro and khaos rails are the same. (Split the difference)
