tunnel icing issue

[tippmannator]

Im riding a 2013 nytro xtx and am having an issue with ice build up in the tunnel. To the point the the ice will begin rubbing on the track while riding... I did a search and didnt find anything on this... just seeing if anyone else has run into this and how they resolved it

This is well known problem on all Nytros. Most ppl remove the tunnel protectors, but that only helps, not completely removes the icing. Best and easiest fix? BRING A HAMMER ON LONG RIDES!

With the cold weather we've had it's going to be a problem. A tunnel block off kit helps a bit. Check out OFT or Schmidt Bros. Both have kits. The icing can also block cooling (wall of ice prevents snow from hitting heat exchanger).

Be ready for lots of noise when the ice breaks free.

Those plates alone don't help much with icing but a tunnel block off along with a tunnel protector plate will.

Yep my tunnel protectors are out, still builds up. I made a ice hammer out of Nylon stock, use it on the running boards too

 

[grizztracks]

I don't believe removing the protectors helps as much as adding a plate between them. The plate blocks the snow from hitting the muffler and forming ice.

Tunnel Icing

I painted mine this summer with between the lines designs tunnel kit. I had a lot of ice build up my last ride on the rear of the machine(@60lbs) the rest up inside was clear except for the skid. Temps were 5-7 deg f and we had to go thru a couple of water bars(that didn't help). I carry a hard rubber hammer to break it up on my machine.

Same issue here also, I just use a plastic head dead blow hammer an make sure to pound it all out after or before riding again.. If its cold and light fluffy snow build up gets bad.. Rubs on the track .

Do you think you get less build up with that paint or is it useless? I just want to get rid of the build up I get along the sides where the track rubs giving the annoying vibration. Next summer I know that I have to do something, either paint or powder coat. Wich ever works the best for buildup prevention.

X2 Grizztracks:

In my view, the ice buildup is mostly a result of water coming from the muffler and much less so from the header section. It has a huge surface area and all that snow dust converts to water and it dumps tons of it into the tunnel. A block off plate will reduce the amount of snow coming in contact with the muffler and thus reduce the problem.

On my MTX I have a Yoshi muffler installed. 80% of the muffler is above the tunnel and for the small part that is inside the tunnel, I installed a small deflector. Trail riding or running in a ton of powder, the tunnel section rear of the deflector does not build up much at all. I normally get two ice chunks form on either side of the deflector going forward but they are small and usually break off while riding, or at least they don't grow.

I did a test one time to see how much ice buildup I was getting on the sled, and where it was situated (from the skis to the rear flaprs) and I can usually keep it below 50 lbs which is pretty typical of any machine. The majority was IN the skid and not above it.

Have a look at the link below, gives you some idea of where the ice weight is on your sled.

does the block-off plate cause any issues with heat under the seat from the exhaust? I have attached a picture of my sled after 150 miles yesterday on the northwoods trails in WI. when it was only 5 degrees F and the trails had just been freshly groomed. The amount of build up made the sled handle/ride like I had a passenger.

This is how I fixed my issue. Very similar to Grizz's

Canoehead what kind of material did you use??

I gonna get that made at work

A hammer and some skid banging jumps keeps it clear.

Just get in the habit when u stop to wait for others give a few kicks to the tunnel and u would be surprised at how much it knocks off.... But the block off plate is 2 on my list moutaintech skid plate is first
