anyone running a p-85 in a 07 Mach and if so list weights and springs and mods to make it fit also.

Sell the mach z and buy something better.

you cant run a p85 in an 07 machz if it has reverse you will break the belt everytime you put it in reverse.

And this is coming from the mouth of someone with a 900 Fusion? With a staggering 200 miles!

I know the guy he's a good friend of mine and I have 2800 miles and will drive circles around that sled in any snow condition,so relax.Some guys are so f***** touchy,it's almost like you bleed yellow or own the company.

900cfi is that the sled with the 1.750 track on it looking for big top speed?

Yes this is the sled. He is going to put on a 136x1.25 now and this should get him back up to some good speeds.I'm not to familiar with ski-doos so any help would be good.I just think he should be running a bit faster than my 900 mod or atleast the same speeds.

Yes the ski doo tra clutch is a wonder full piece.But I wish it would have came with a cat,polaris clutch maybe its because I already know how to tune those and this tra is new to me but so far I dont like it I have a few more things to try and if I cant get it right I'm gonna move on to a different clutch also.Between the clutch kits and other componets I'm at about 700.00 dollars yea some one shoot me in the head.

i am in the same boat no problem with the polaris clutch but Ski-doo you have to pull them off to make a change , and that is a pain in the ass, not enough time to do that .that is why i was asking about a polaris clutch.

The only thing you can really change without pulling the clutch on Poo or Cat clutches are the weights. That's the reason for the clickers on the Doo clutches. Get yourselves a puller, clutch holder, and a BIG ratchet, it's really not that difficult.

you can change weights in a polaris in 5-min not a doo
