Aftermarket pistons for 800R?

[Mr.Plow]

so its time to install new pistions in my 2008. should i go with stock BRP pistons or an after market piston? RK Tech, Wiseco or some other manufacture??? any thoughts? mostly stock sled that is used for boon docking and mild hill climbing.

Every one will have a different opinion, i dont believe in the wiesco in the sleds unless you are dilegent in letting sled warm up properly on every start up, We have had 2 sets fail within 1000 kms in the last 2 years but i will say they werent propperly warmed up all the time. As for stock they are only a single ring and expensive, i personally dont mind the stock pistons at all. Kore on here is selling the new MCB kits with moly coated rings that are suppose to last the life of the pistons for $350 i believe this includes everything bearings, gasgets, I am about to put a set in one of our sleds, i havent heard anything bad about them, i have no experience with them due to we usually have catosrophic engine failure so we usually go with a new shortblock. But im sure a few people will pipe in and give you there experiences, good luck.

Whatever brand you go be sure to get dual ring. The factory single ring is a joke imo.

was thiking about the same thing, duel ring all the way. Leaning toward RK-Tech, you got any experience with the RK-Tech pistons?

Let me know how the installation goes. Very interested in how they work out.

They actually wont be getting installed anytime soon. Long story. I have had them for a couple years and ended up going big bore before i had a chance to put in the RKT pistons. I have a SHR big bore which is a RKT head with big john's porting and cat pistons. One day tough i will get some use out of them.

I put the drop in kit in last year. Nice looking pistons. I do believe they have milled some weight off compared to stock. As for installation I can't say there is any difference than a stock unit. And as for performance I can't support any increase claims but I am sure I did not lose any power. It runs exactly like before with one difference in that it doesn't heat soak on long runs and back to back. -Dual ring benefit!

I put these in last year.... really happy with them....

I installed the RK Tech dual ringers before last season in my XRS and it ran strong all season long! They come with caged wrist pin bearings that makes installation fairly easy.

Read in the new Snow Tech magazine that doo has a updated piston for the 800r. Same piston as the etech or something. Any DOO guy has more info please? Thanks

if dual ring is such a "hot" thing BRP would be running them

With bean counters its a cost issue. if a single ring gets the motor past the warenty periord then its good enough. Good enough is not good enough for me thats all.

Not so sure about that. Everyone knows an oil squirter on the crank bearings instead of isoflex grease would be the best thing BRP could do to their motors, yet they've been doing it that way for years. Can't sell new sleds if your old ones last forever right?

 

[Mr.Plow]

yep, thats marketing for ya......
