Cat big bore only make 12 hp? after market tune and pipe make 15hp? so 20 hp maybe? or bored out bigbore with no porting? if that's what some sell not good. I ran my stock rev with my big bore against a carbon xp and out climbed it, same tracks, no problem, hp rules. spent to much on carbon...

Top end piston kit, get the best kit you can.

Quadtrash, the parts made and designed by Terra Alps are warrantied or garunteed, Terra Alps uses Japanese pistons when possible, set to proper clearances. Some have dealers install the parts which they can warranty the parts and labor install. They might charge a little more but a good dealer...

Funny is when some sell Chinese pistons to those that need reliability to ride the mtns. and feel they have the best. LOL

I beat on mine, pump gas, 66 gram weights at mountain elevation, thermostat kit,Polaris 860 cfi Big Bore Terra Alps - YouTube

best to get a new one with all new bushings, at least it will be good for a few more years.

I love my 930 kit, 2 years on it, pump gas, runs 74 gram weights at 8000' 8100 rpm , that's making power.

I have one, 1000cc cat engine, efi, twin pipes, custom mtn mod.

It could be done but wont make the power our kit makes, reliability comes with good pistons, we use the best.

wider is not always good , wide running boards will drag in the snow and slow you down when carving biggest mistake I see from tunnel builders that don't actually design there own tunnels. Polaris has always had narrow running boards so the chassis doesn't get hung up on the powder. We designed...

good install, should make it rip.

hmmm, maybe you would like to express your self? instead of hiding behind a screen. Your obviously a follower of another company and don't know what your talking about. All the other shops around here try to buy stuff from back east and make it work out west in the mtns at elevation with little...

Takethebounce, wet heavy snow is a load on the clutching and engine. So the vid shows the etec with higher compression billit head, holding rpm on a long pull, with snappy throttle response, which was noticiable when bolting on the heads. We added clutch weight and a helix to this sled. Sure...

We have a good kit out there same as our M series kits, simple and work. Have a few of the slednecks guys running them and they said it was worth it.

If your getting a big bore make sure its fully ported, no use in getting a kit from anyone if its not ported, won't make much more power then stock, and thats a waste of money just to say you have a kit under the hood. If it seized its not from a stg 2 porting job? but from the forged pistons...
