I have to say, I appreciate both weighing in here but would like a (civil) debate.
Saying "you are wrong" and then "you are wrong" leaves us scratching our heads.
Both RK and ID have great reputations, but we all win if our understanding of the technology behind each product is better understood.
civil would be nice. And what we want is to find out what's true & what's hype to make money.
It's this simple, aftermarket shops that are not OEM dealers do not like OEM pistons for one reason..... They are really expensive and there is no margin in them.
It's pretty easy to become a dealer for Western Power, CVTECH, Tucker, Land & Sea, And many other aftermarket companies if you have all the requirements of a legit business.
Then your Pistons options come with 30 to 40% margins .....then in the spring they blow them out at close out prices. Then land on eBay to flood the market with sub-par pistons.
CAST - SPI, SPX, and a few others branded from the same plant in Taiwan. ( not a bad product for the money ) but not even close to an OEM. ** best used in low horse power motors ** ( don't get me wrong Taiwan makes some really state of the art products ) - but you also get what you pay for.
Forged - Wiseco, Woosner ( both really nice pieces but they expand faster & to a bigger size then the OEM Piston. ) pron to 4 corner seize.... Right when you need them the most.
The new ProX that runs under the wiseco house ( absolute garbage ) I got stung really bad by these a fews ago. ( the bad part about this is that Wiseco flat out lied and said they are the EXACT same as the old PRO-X ART Japanese piece ) WRONG FLAT OUT LIE !!
If you go the road of selling after market ( cast ) Pistons its much easier to get the job because the prices are way under 1/2 the OEM Part is.
Which makes more room for labor, the over all service bill is much less. And the margin live able.
Then move to Wiseco Or German made Woosner expensive retail price... Running on and flying the FORGED flag ( strong faster better )
30 to 40% dealer discount on a piston that has a much higher retail price means of course 30 to 40% of a much high retail price. ( more profit )
Then you take shops that contact Woosner & Wiseco directly and ask what it takes to get distributor prices..... They give you a qty number and then you buy 40 to 60% off of retail.
Then you see all the racers running around with Wiseco stickers on their sleds that have OEM pistons in them that helps people think they are great.
The bottom line is this........ I don't run around forums and Facebook ramming scare tactics up people's butts to get them to tear a perfectly good motor apart and install something that's sub-par compared to the OEM.
I'm 55 years old and I was running around my dads snowmobile dealersship back in 1968 thru 1975 and you couldn't drag me out of there.
I have plenty of business, and letting nature take its course has been just great to me & my family.
I am not here to get any business.... Right now on this thread I am here for one reason..... To make damn sure you all get a fair shot at what is the truth for what's best for your Polaris motor.
I say the only real way to find out some accurate info is to have a contest.
Need volunteers- all brand new sleds.
We need 2 riders from the mountains
And 2 riders from the flatlands
Requirements must be at least 5000 mile average per year.
Indy Specialty will build 2 of the motors ( the only thing Indy Specialty will do to the stock motor is HG7 Hone the cylinder and put it back together )
RK-tech will build the other 2 motors.
Sleds get no special treatment - basic warm up, and normal maintenance.
Would prefer riders that ride hard and ride when it's really cold not just sissy riders that ride above zero.
All riders will just simply ride until they fail.
The first sled to fail that builder owes the other shop $5000 dollars.
When the second sled fails $5000 goes to the other shop.
Last but not least - none of the 4 riders can be friends or pals with either shop owner.
There is nothing worse then a sand bagger that pushes a lie for free products.
Or we could have a simpler contest....
What shop answers their phone if a customer calls with a 4 corner seized piston and wants warranty. ( or who has the largest number of customers that have been told..... You must have bled it wrong, you must have cold seized it, you didn't warm it up long enough ) and so on.
Either contest is fine with me.
Or we could let the forum members pick a contest they think would be better.
I am game to show where the real piston truths are.
** ( let's all keep in mind this all started from a RK-tech customer * xpturbo600 * ( not RK-Tech ) claiming to be a piston expert.) ** - xpturbo600 was cheerleading and fly a flag he knows nothing about ** do everyone a favor, don’t give out " Fake News ( Fake facts that are leading people to something you know nothing about )
And that's just plain 100% not true. Fake News.
Let me be perfectly clear I am not suggesting that every one run a 150 plus horse power 2 stroke 5000 miles without considering a rebuild if it starts to show you signs of power loss.
But my experience points me to what I know is very possible...... I have seen in excess of 15,000 miles on a OEM stock Polaris 800 motor flatlander sled. * ( this customer installs swimming pools in the summer and he has all winter off ) *
His 2008 dragon went 12,000 plus before I rebuilt it.... ( it was still running & he still owns it ) his 2012 went past 15,000 and was still running... ( I built the 2012 into a Long Rod & asked him to run it until it stops ) my gut says it will go past 20,000....... And it will take 4 new drive clutches to get it there. This guy installs a new clutch every year and a new oil pump at rebuild time. And his chassis maintenance is off the charts.
My experience tells me ....There is no piston other then an OEM that could make that journey.
