Longer Snow Flaps - IQR Polaris Racing Flap

[307 Snow*Moto]

Im looking for about three longer snowflaps. I know at one time Polaris made a long flap for the Polaris IQR sleds and up until last year you could get them. Does anyone know where you can get longer snowflaps these days. These big mountain sleds seem to keep getting bigger lugs, and bigger lugs mean bigger chunks of snow getting flung back and because everyone seems to always be behind me I feel bad...hahaha.

Yes I know you can feel bad with those chunks hitting the riders behind you.

Been on a few rides when I get blasted being TOO CLOSE to the rider in front of me. Got a few ... why do you have a fat lip stories.

suggest not to get a longer snow flap.

The rear cooler on most RMK mountain sleds are at the rear of the tunnel directly infront of the track flap.

Too long a flap and the track grabs it and tucks it between track and tunnel.

The flap between track and tunnel greatly reduces snow and air to the rear cooler.

The sled will heat up, you stop and can't figuire out why is is heating up like never before because when you get off the sled and remove any rear sag , flap comes out as you get off and you don't see the problem unless the rider behind sees the flap tucked under.

The rider to the side of you will see it but the rider behind you won't because even more debris is flinging off the track since the snow flap is tucked between tunnel and track.

If you really have to do this get a semi trailer mud flap (laying on the side of the road) and cut it down to size. Heavier material and harder to get and keep tucked under.

don is mostly right, the flap actually serves as a wind breaker helping create a negitive pressure inside the tunnel causing the snow to get sucked inside along with keeping stuff from flying and creating fat lips!

as for the flap being to long and getting sucked in, thats mostly right some do and some dont. I used to run just rubber belting on my turbo and it always got sucked in and would make it run warmer. my 1200 needs tons of cooling, running without a flap didnt help matters any. I now run a long piece of rubber belting with nylon inside that has a coating of PVC plastic on it, (makes it shiny and smooth) but what happens is when it gets cold it gets really rigid (from the pvc coating) and I have yet to suck it up in my tunnels (both dual angle mtn tunnels really high at the flap, one vanamburg, the other a holz) with the rear skid fully extened I have about an extra 1" on the ground so when I hit a bump and everything is in the air it wont catch the bottom edge of the paddles and get sucked up!

So the longer flap is so long it (almost) drags on the snow?

Not the best pics but hopefully the idea gets across.

Just call up Wahl Bros Racing and order up some snowflap material, they sell it by the foot ($3.85 a foot?) After you rivet it on, cut it at the bottom where you see fit. The edge in the pic has two nylon straps bolted to the flap and then to the rear bumper. (jus like sno-x guys do) Been like that for years. I had the same problem with that Edge years ago, too much roost and now the cooling is better with a longer flap, not to mention the more pliable flap is easier to deal with when you bury a the sled.

yep!

and you can see the little bit of my 1200 in the background with the polished tunnel on the right, but like I said its rubber belting with nylon webbing in it with a pvc coating on it so when it gets cold it gets rigid but not so hard it gets in the way when getting unstuck like mentioned above!

That same thing happened to my sled this weekend. The sled started to heat up so I put the scratchers down, still got hotter stopped and saw the track had grabbed the snow flap. Fouled a plug 30 min later so I'm blamming it on the high engine temp. I have been raising the track when not in use with a 4 x 4 post and it bends the flap towards the track.

With a rear flap as long as it is ... what happens if you go in reverse?

It seems with the sag resulting from driver weight there is an increased chance of the rear flap getting tucked under the track and snow resulting in the track ripping the flap off? This would occur in reverse or rolling backwards?
