I love this sled and am just beginning to realize its full potential. As I make changes, I figured I may as well contribute to the countless posts others have shared with their own mods, updates, improvements, etc. I've moved alot with the military, was unable to ride several years, and have only had the chance to log about 700 miles on my CF7 since I bought it late Feb 2011.

My family has many Cats, my last 3 personal sleds were a 2005 King Cat 900efi, a 2001 Mountain Cat 600efi, and a 1999 ZR 600efi. Not knowing what the Crossfire was capable of, I was still greatly impressed with the ride and the power the first time I rode it. I've done alot of reading and wrench turning and this thing is really starting to come alive now.

I bought it used with 1,400 miles on it from the original owner. The Black Hills are about 4,000-6,000 elevation but he had it clutched with the 6,000+ helix. It had stock clutch springs and a Shift Assist installed with weights for the Black Hills elevation. Like I said, I was impressed with that setup, the Ripsaw track, and poor belt deflection.

I rode it the way I bought it for the rest of 2011. It came with M-series skis, a windshield bag, tunnel bag, MBRP can, and decals that the original owner liked better than stock with a matching white windshield.




I spent the majority of 2011-2012 winter deployed. This gave me plenty of opportunity to look for things and read online when I wasn't flying. I ordered an AMR graphics kit along with a black windshield to replace the original owner's decals. I also bought a 144" track but the extensions I ordered never shipped and after several weeks and a phone call, I cancelled the order. The only other thing I did in Feb of 2012 was pull the DD, clean it, and drop in new fluid.









I deployed again in July of 2012 and just returned a couple of weeks ago. I couldn't decide if I was going to buy a new ProClimb, a leftover CF8 H.O. or just spend some money on my CF7 to make it better. I found out last fall that I'm moving to Colorado Springs in May. Catch 22...better riding in CO but I started saving money to buy another house, so the CF7 with some updates was a cheaper option than buying a new sled.

I ordered a set of Ice Age 144" black anodized rails. After some research, I realized that required a set of 8" wheels and an axle to go with them. I thought the stock wheels might work but they do not. I did ride 100 miles with the stock 6.38" wheels extended all the way out. There was some slack in the track and the rails tips rubbed a little, but not bad. I installed a BDX 2-wheel kit and when I went to swap the upper idlers with the inner rear 6.38 wheels, I was surprised to find that was already done. The Ice Age adjusters didn't work but the stock Cat adjusters bolted right to the Ice Age rails. The only remaining problem is the outer front wheels will not bolt to the Ice Age rails. This will need to be fixed with a dremel and it is unfortunate since I paid extra to have them anodized and now I have to grind away at them just to get a basic bolt on swap to work out. The 100 miles I rode last week with the small rear wheels was still a huge improvement. With the dremel mod I need to do, the final rear skid will be a 144" track, 144" Ice Age black anodized rails, two Ice Age 8" wheels with a BDX 2-wheel kit, axle bushings from a Cat 8" axle, and 6.38" upper idlers. It looks better than stock and is a completely different sled on and off the track with the Ripsaw left in the garage.








After reading many opinions, I opted for an M-series seat. With the black tunnel, black skid, and plans for black belly pans, I wanted to find an all black seat. With some patience, I was able to pick up a brand new all black seat for about $225 off of EBay. It was definitely worth the money. The storage is great, it is lighter, it looks better, and the riding transition from sitting to standing is great. For the money, I'm not sure which was the better mod so far...the seat or the skid/track. They were both definitely worth the money and I'm glad I changed both.

The last thing I'm going to change this year is the clutching. I honestly don't mind the setup right now, but I realize there is quite a bit of untapped potential. When I did the track and rail swap, I installed the new aluminum belt adjuster and set the belt deflection correctly. The belt has riding a little low in the secondary, but nothing bad. Needless to say, setting it correctly made a huge improvement. I didn't want to change the clutching, then have to adjust it again once I added the 144" track. For now, I'm not planning to touch the primary. The secondary with green spring, Shift Assist, and 36* helix pulls pretty good. I plan to try to stock 44/40 next. After that, I'll either install my Formula X-1 kit on the stock 10.0, or try the stock setup on my new BDX 10.4 HD. It will come down to time more than anything. I plan to swap the belly pan before I try the 10.4 clutch. I know I can cut the stock pan and add the tub piece for the larger clutch, but I think I'd like to just order the black pan while I'm at it. Until I get that done, I figure I may as well run the 10.0 stock clutch and see the changes on the Formula X-1 kit.

Parts sitting in my garage: BDX Rock Rollers, BDX 10.4 HD secondary, Formula X-1 clutch kit.

I still plan to turn down the oil pump.

I'd like to install Fox Floats up front.

Once I get a couple hundred miles in CO, I may gear a bit lower too. This might end up being the girlfriend's sled next year though depending on what I buy next. Honestly, I think I'm probably going to look for another Crossfire, for the money they're amazing.

Sounds pretty sweet. Can't wait to see the pix. If you are running 60/60 gearing, I would not change it. Just clutch it right. Aftermarket pipes work better than aftermarket cans. 144 track sounds intriguing. Which one did you end up with?

If y0u are switching out plastics, you might want to consider getting M plastics for it and putting an M can on. The 06 crossfires are the odd duck of the lot for exhaust as they exhaust out the bottom vs. the front like the M's and all the other CF's.

It's better having it out the front in deep powder anyway, and I'm having a harder time finding an ultra q or slp can for the 06's, as they were the only model and year with that style. The exhaust pipe is the same either way. Not sure what else exactly you'd have to change. I'm looking at doing it to one of mine though.

I realized tonight that I don't have any pictures of the new track, seat, and 8" 2-wheel kit installed. It's on the trailer under the cover in the garage right now so maybe this weekend I'll be able to add a few more pictures. I really like the all black skid. The wheels are all black, rails are black, seat and tunnel are all black. I'm thinking I'll buy black A-arms as well or else have mine powder coated.

I also did the 144 ice age rails powder coated orange with 8 inch billet wheels man that was a sweet upgrade. I wished I had gone with the M seat instead of the boss but its good enough. let me find a few pics..

My next mod will be replacing my 9000 mile clutches with something aftermark I was thinking a comet primary and a BDX 10.4 HD secondary but I still need to research it more.

swamper, did you have any issues with the front sets of single mount idler wheels mounting to the Ice Age rails? Mine DO NOT fit. It's going to take a dremel and a few hours of grinding thr rail edge to get the aluminum stock mounting piece to fit flush against the rail. I already broke one of the brackets trying to tighten it down to see what I could do. The rib on the Ice Age rails is too fat and too deep to get the brackets mounted flush.

Hi Nubby I had the exact same issue in fact I broke one as well!!

Little grinding/buffing fixed it right up but DON't GRIND YOUR SWEET RAILS grind the bracket piece, and I also orb'd my holes a bit... This way if you wreck your 10 dollar bracket it's easy to get another one from Cat but the rails are a lot of money I would leave them alone.

I think these rails are a spin off the Polaris factory and this company is like a sister company for just aftermarket goodies. (i might be assuming a lot but I went right down there and picked them up locally and that was my understanding...) One thing I wonder is if I need new sliders do I just go get them from the Polaris dealership because I have a feeling they will fit.

I would hate grinding the rails for what I paid, plus the anodizing. I would need to take quite a bit off the brackets though...to the point that I think they'd be pretty weak. I was a little disappointed they didn't fit for as much as I paid for the rails.

The guys at Ice Age told me the rails were made for Polaris slides. They said Cat slides would fit but they'd be really tight. I thought about buying black slides from Polaris but the white slides only bother me when its on the trailer...in the snow you can't tell.

I have loved the 144" Back Country track and Ice Age rails...until yesterday. With limited snow the 2-5 miles to and from the trailer, I overheated several times. I don't have scratchers which would have helped and I'll be installing a set before next winter.

I don't have the front 4 idler wheels installed due to the bracket fit issue. It looks like I've already toasted my set of white slides so I'll find out shortly if the standard black Polaris slides work. They're worn pretty thin where those 4 wheels should be. Between the lack of snow and the lack of those idlers, I'm hoping it didn't wear down to the rails. It looks fine for now.

How did the back country act on the trails. Has it ever overheated on you before or just since the snow is melting. I was looking at it in a 136" not to sure If I wanna go to the 144". You could look into the new yamaha sliders with the graphite or something in them. They are supposed to be pretty tough. Something to look into.

My Dad bought his CF7 with a 136x2 on it. I've ridden it and I think it is a good option if you want to stick with just a track swap. I am glad I went to the 144 though. The only reason I had cooling issues was from the mud and ice the couple of miles to and from the trailer. I was surprised the other snowmobile with me didn't have issues also.

I was able to ride the Saturday before this recent past weekend. I could have easily went out again on Friday and Saturday this weekend but had other things to get done. I woke up to 6" of fresh powder this morning and it is still coming down. I put my new Yamaha 212x in the garage on Saturday so I'm ready for warmer weather!

Unfortunately, the new 10.4 BDX HD clutch and Formula X-1 kit remain in the box. I still had a blast riding this thing with the current clutching, new rails and longer track. The M seat was money well spent as well. Over the summer, I still need to install the HCR skid plate I bought last year and I think I'm going to update the belly pan plastic to black on the bottom but leave the nose and side panels green since they already have decals installed. I wanted to update for the larger secondary and I think I'll go with the front dump/newer style so I can run an M-7 can.

It is weird to look at the pics from when I bought it and see all of the changes. Here is the day I brought it home:


These are from last weekend:

I don't have the windshield. I wish I had kept track of what I've spent to see how much I actually have in the sled. I paid $3,900 for it in February of 2011 with 1,400 miles on it. Except for the decals/graphics and the clutch kit, I've been able to sell every stock part to get some money back for the upgrades.

I paid $240 for the seat and sold mine for $50.

I paid $400 for the rails, wheels, and axle and sold the stock 136" for $125.

I sold my stock Ripsaw for $125 and bought my Back Country for $125.

I sold the white windshielf for about $25 if I remember correctly and paid around $75 for the black one.

Between the graphics, clutching, bellypan and the difference between above parts, I probably have just over $5,000 which is more than it is worth but that is also from over 2 years ago when I bought it. Plus, this is mine and I like working on things and making them the way I want.
