Im curious if anyone has 2 cents on why my crossfire 6 brings on a goofy vibration as soon as I jump off the hard pack and blast around in the deep powder. The sled reacts awsome to the fluff and does everything I want, however a wierd vibration and a dull sound comes from down underneath, but only when in powder. Its not a scary feeling to me because as soon as you get back onto the trail, the thing just rips and forgets about those issues. Its just annoying.

How loose is your track?

CAREFULL! rider beware ... thats what mine felt like seems like a loose track issue hahaha i wish thats all it was!!!

I have an 06 xf 700, and i get that same vibration and sound when i am in the powder, but i also get it after alot of powder riding and ice up in the tunnel. FlyinRyanF7 what did your problem end up being?

tips of the rails hitting the windows in the track slightly causing noise and vibration... i know my m8 does the same thing... not always but once in a while.

look under your front skid shock... see any nice shinny spots where the track drivers are hitting the cross shaft?
Mine did the same thing, installed a set of wheels right in front of the front skid shock and no more issues...
How many miles on your hyfax? may be time for a new set?

just over a thousand miles on her. Ill check the track tension tomorow, thats a good idea which I never thought about. Dealer got everything set up for me and I havn't done anything to the rear so I guess I forgot about that- duh.

You got it...

go on black diamond site they have a set of wheels for this problem
