Well what started out as a red 136" Attak has now been upgraded.

-38" Ski Stance
-Excell Exhaust
-Hartman Inc 151" extension kit (tunnel & rails)
-8 tooth extrovert drivers
-2" x 151" Camoplast Series 4 track
-Slydog Skis
-Ulmer Racing modified clutching

The next step is to add a supercharger, but we'll make one trip to the mountains before we do that!

Looks good ;)! Is that the ride you're taking to Muni next month?
 
Allen, I'm going out the 15th-18th and the 27th - 1st of this month, We should hook up. Killer snow out there right now. I'm sure we can get that 151 buried up to the handle bars :) ===SRXSRULE===
 
Looks good, are you coming to Revelstoke?
151 is a short track there now, isnt that insane?
 
Mighty, probably won't be what I'll have in Muni, planning on bringing 2 short tracks.

Eric, I'll see what's going on. Swamped with work right now. I have 3 supercharger installations to do in the next 3 days, busy, busy, busy.

Kb, revelstoke, that's way too damn far away!

Lb, the customer didn't want a 162" track. He wants to be able to ride it in low and high elevation. He told us what he wanted, we built it from there!
 
I have had probs with the 2" track working under the attack skid. I haven't got it figured out yet but is feels like there is not enough room in the front to push the snow through the front heat exchanger. Might have to do 7 tooth drivers :o| :ORC So be ware of that. I am really disapointed with that aspect....
 
Yes protectors are out.

When the track makes the turn over the drivers is the problem. I think.

When you get in deep snow the snow gets "trapped" in front of the drivers. There isn't enough roonm for it to displace the snow that hasn't left the track. Maybe holes in the track will help this???....

I have 8 tooth. Mtn. apexs have 9" and I bielieve a lower chaincase. There is only, maybe, an inch on the attack,at most as the drivers makes the turn in front of the exchangers. That is not allot. I can barely get my had in there!
 
Well when you run it you can hear and feel a humming. Especially as you hit deeper snow. It just sounds like your trying to PUSH the snow. Loosing RPMs as you get in the deep.....

This just sounds like a track not cleaning the snow out from the rotation???? I am stumped....
 
Huhhhh....derrrr....wellllll

I thought just for a look see I went out to look at my 8 tooth drivers. Somewhere along the way I got 9 tooths put on it!!! I have no idea how that happened because I had the 8s with the whole kit and just got one swappped somehow.

Anyways....problem solved. Thanks for trying to help out guys!!!
