Removing the lower heat shield and the secondary shaft will give you a lot more room and they are less time consuming than removing the engine.

My setup is not far off your listed setup. Same lug height, gearing, weights and helix, similar exhaust setup, but more rivets in weights (run very close to sea level). The Arctic Cat green secondary spring (at lowest possible preload setting) works for me. More axial preload = better back shift...

Also, it seems like Arctic Cat did not do the full homework regarding the 2013 skid mounting holes: http://www.arcticchat.com/forum/cat-ser ... sleds.html

Some requested measurements from the Lightweight Rear Suspension Kit: Center shock upper mount to upper tube of center swingarm: 37.8 mm (1.488") Rear shock front mount to lower tube of center swingarm: 93.3 mm (3.673") Pull rod front mount to lower tube of center swingarm: 128.3 mm...

If that is the case, do not start the engine...! A damage like that can only happen if something hit or got caught in the primary clutch. A piece of ice, a spare belt, something you hit on the trail, still less than necessary to figure out. The important thing is to make sure that your splined...

My lower bumper bolt is 310-320 mm (12.2-12.6") above the concrete floor, dry sled with no rider but full of fuel, depending on if the front suspension is compressed or extended before measurement. 2011 MTX SE 162", narrow Skinz front end with OEM skis at full narrow, ski stance 915 mm...

They fit only the new style tunnel, not the 08 and not the 09 non-RTX-XTX tunnel. Also, the instructions supplied sucks. They basically tell you to just drop them on the running boards, drill the holes and install the rivets. If you do like this, you will rivet them on top of existing rivets on...

I like it better than the OEM skid. The overall feeling is softer and plusher. The weight transfer becomes easier to control with body position which means you decide when you want it to wheelie or not. Also, I get the feeling it does climp up on top of the snow instead of trench when you...

In my opinion, that sounds like the typical behaviour of the stock skid geometry. Your description sounds very much like my sled before I went with the Lightweight Rear Suspension Kit (= AC geometry). Apart from improved control over the weight transfer characteristics, the Lightweight Rear...

I agree from experience - ski stance has got zero effect on darting. If you are trying to reduce darting, I would do a "search" in the following order: 1. Make sure that all front end bushings and joints are in good condition without excessive free play. This has got a huge effect on toe...

The previous generation Challenger Extreme had part number 9943. The current generation has got part number 9175. Though, both of them are 162x15x2.5 and the pitch is 3.0".

If you are looking for a perfect mirror finish, you will be interested in wet sanding followed by polishing with Mothers Billet Polish. Mothers Mag & Alu Polish and the Busch stuff is too aggressive for a perfect mirror finish.

If your package size is under the magic 108", it is difficult to beat USPS Priority International. Above 108" you have to go UPS, TNT or DHL which is a lot more expensive.

2.5" is maximum, unless you do a radiator delete and / or different drivers.

In my opinion, the Challenger Extreme is the best track available...! Much better drive than the stock Maverick, in fresh powder as well as wet and heavy snow. In general, better durability too. Have a friend that has trashed his CE with 270+ hp during 2000 kilometers and the track still looks...

PM sent.

Except for worn out exhaust donuts, cracked flex tubes as well as cracked header pipes are quite common. You might want to check on that.

Don't forget 2014-T6 and 6082-T6 which are very common around here. I don't know any numbers in standard units, but they are normally referred to as the second and third strongest after 7075-T6. The drawbacks are that they - like 7075-T6 - do not bend very well. They are also - like 7075-T6 -...

Exactly. The problem is not the cooling capacity of the radiator itself (which is more than enough) and the problem is also not the supply of incoming cold air. The problem is the evacuation of hot air behind the radiator. Open up the back of the hood and the front of the fuel tank cover and...
