Yah.. i beleive that they wotk on the 670's just fine. But not 800's.. the reason that i like the tra better is because that is the clutch i know bwtter.. But i always try to learn something new everyday..
Then why does Mountain magic run p85 and team secondary on all there sleds? I understand that you guys are direct competition but his sleds seem to do pretty good and i don't think he would consistantly use p85 primarys if they took our crank bearings.
Sorry MODS for adding to the hijacking.

Not sure why they'd do that.. The hcx secondary is a by far better secondary clutch except for the fact that you dont have reverse in the snow with it, it will back off of a deck or out of a trailer though.. Ive seen way to many people that have put p85's on 800 twins that have taken out cranks for my likeing even when they started out with a new crank and they were balanced clutches.. Maybe they aren't familiar enough with tra's to be able to tune them well.. They are completely different than a p85..

Is balance an Issue?

If you are running a p85 i'd definitely get it ballanced.. It's just easier on everything..

Ken has ran P85's on his triples and and other sleds for alot of years and know's them well.. But these are just issue's that we have found.. And we just dont like usung them in a situation wher they have been known to create premature crank bearing failure.. But that is just our opinion and decision...

They have done things in past that didn't make sense to me either like putting a turbo on and having the intake side facing the brake rotor where i'd get any brake dust thrown right into the turbo.. But hey it must have worked for them i guess.. But it is just not the way i'd do it, and yes there is more than one way to build a sled.. No one has all the answers or the perfect sled.. Or laying a chaincase right down and yet not dropping the axle lower in the chasis, just moving it back in the chasis.. I have never figured out what that would accomplish.. But these are just my personal opinions and idea's.. Like i said before no one has all the answers..

Hahahaha.. Man it's all good, not interested in gettin into any pissin matches, just giving my opinion and knowledge.. It's hot !! Need Corona!!
The biggest down falls i find with the tra are that they are an extremely heavy clutch do to the excess aluminum they use, which in turn traps heat and a hot clutch slips making them very ineffecient. They are also a pain to do any trail tuning with, there are parts and pieces that fall out when they come apart, short of having a tool box with you to service them GOOD LUCK. IMO there are far better choices for primary and sec clutches than a set of tra clutches. As for the 800 rumour, which 800 are we speaking of here glen. I dont have enough fingers and toes for the number of 800 doo engines i know of that have a p85 and thats not including the 900 crankshop big bores that run the 800 bottom end. Back to the 670 part of this thread IMO for any 670 there is NO better clutch than a p85, the 670 being a small engine in comparisson to todays engines loves the light weight of a p85, aswell you can load the engine up fast and hard, being the 670 has a relatively short power and torque curve it allows you pin point that curve and use all of it.

I was referring to the 800 ho motor.. But like i said before it boils down to what you are familiar with.. Personally i dont find the tra hard to work with but i've been dealing with them for many years.. I dont have anywhere's near as much experience tuning the p85. Deano if you've been able to have success with the p85 on 800's then good on yah.. I was just talking from what i've seen and experiences from other people that i've worked with over the years. But hey there are always more than one way to do something as we all know, and see lots of the time on here.. I'm just giving my personal opinion.. If you've had success with the p85 what have you done differently?

IF you have not had the 800's have crank problems with balanced p85's.
For sure its all good, not tryin to start anything. you guys build awsome sleds also i just never heard of a p85 causing crank problems on a 800 doo. Now beer me it!!:d
