What has worked the best to get rid of the block of ice that builds up in the tunnel? I can not possibly see how I could ride multiple days. I do know it weighs more when I come back then when I go!!!
Thank you

A rear heat exchanger, unfortunately its an involved modification.
It eliminates over 50% of the buildup.

We have 2011's MTX's and get hardly any ice build up. I put a 3/4 block off plate in my sled and nothing in the wife's sled and we both get the same amount of ice build up which is very little. My buddy has a under tunnel exhaust on a XTX and holy crap did that thing build up ice. after 5 hours melting down in a heated shop I pulled out 2 chunks that dropped from the side of the tunnel and I bet they weighed 20 pounds a piece. There is now stud protectors in the tunnel and a block off plate has been installed.

I just hit the tunnel with my boot every other stop or so when riding, then use a non marking rubber mallet at the end of the day to knock out the rest. This gets about 99% of the ice from the tunnel and only takes a couple of min.

Slush is my biggest problem when it comes to ice build up. I agree with Lund....only a rear heat exchanger will fix my problem. Slush buildup (which turns to rock hard ice) is different from just snow buildup from powder riding. It is a real problem. Even my mud flap gets jammed with frozen slush.

I have a 08 with a custom turbo setup and even with an arctic cat rear cooler and hard line plumbing going back there it still gets a good bit of ice build up. Less than a stock I think with the cooler melting alto but still more than I like. I am changing my tunnel Ext and bumper out and am going to try some CNC plastic for my tunnel to see if it will help not build up. Will see this weekend!

I do have an under tunnel exhaust and it exits at the very rear. My issue is the whole tunnel gets it front to back where ever the exhaust is not. I have ridden this way for a few years now but I am wanting to go on extended trips and would like to reduce the build up. Part of the issue this year has been everything has over flow.
I am not real sure how I would plumb around the exhaust.

The ice does fall off though. If you hit bumps it cracks up and falls out.
You can bring a rubber mallet and tap the tunnel and it will also fall out. It is held in very loosely and any twist to the tunnel or bang and it will drop.
You can buy teflon sprays too that help. Never had an issue on my mtx but i did on the xtx. Used the mallet a lot and then started using sprays and it worked.

I just used a double run of 1" aluminum piping and just ran them both down the right side( mine was a FX shorty before the change and did not have the MTX cooler), just looped in a cooler(arctic cat). I would think you could remove the factory MTX cooler and run your own lines and a cooler out back, the line and cooler are melting slush, plus the exhaust. Seems it might help take some weight off?

AKvector, I now use silicone spray before each ride on the underside of the tunnel and on the skid of my 164 '11 MTX which works great for reducing ice buildup for me here in AK. You have to spray it before each ride however. Does not require a lot. Like the others said regularly knocking any other ice off also helps a lot. This way I get much less buildup than even on my brothers XM.

OK,, weekend testing and with the 15" wide( stabbed my 16" Last year)
and wet snow the cooler and exhaust was the only melted spots under the tunnel. Sled must have weighed 140 extra pounds!!!! It was like dragging a dead body around!! Turbo was working overtime. Found some Surefoot Coating, ordering today and will tear down the rear tommorow. Supposed to coat and last the season, we will see and let you know.

Hi guys, I gonna try the new Hammerite dual protection paint to minimize snow build up.
It claims to be very water repellant, so it should repell snow and ice also.
All Hammerrite Paints have Silicon in it(to my knowledge), so with Jagos having good luck with Silicon spray it should work.
My sled is in a teardown right now, so I haven´t tried it yet.

Definitely would be interested to find something you could once a year.

There is no real easy cheap solution to this problem, Yamaha's poor tunnel design is prone to this.
The best solution out there is to replace the entire tunnel with a carbon fibre tunnel.
Your next best solution is install a tunnel U-cooler like this one. Ice will build some on edges but not in the center, it will reduce the snow buildup by over 50%, any other design is a waste of time for the work involved.
