Turbo axys piston change interval
- Thread starter ez-ryder
- Start date
stock pistons, reeds, I'm around 1400 miles. boosted since 400. As long as compression, etc, still checks out, I plan on running them till 2000-2500 miles.
I have personally seen my buddies 14 pro 800 silber over 2300 miles, stock pistons, reeds. Seems like they last longer then what the INTERNET tells us they do!

As in my post from last year- All checked out for me on my 16 Axys, even with a full leak down- but at 2K boosted miles on the clock -It was worth pulling it down mid summer.. to cure the wonder I had rattling around in my head.
She would have ran fine but the gouge in the wrist pin ( lucky find) and no check except a tear down would have caught that, and no explanation where it even came from, was a diamond in the rough.. still worth a tear down IMHO if you even have a concern. I put almost 1,000 miles on last year and she has not lost a beat..The 15 pro pistons were a favor from TRS-as that was the year of solid pistons from Polaris... Just hiding and waiting now.till the 2022's come out..... no reason to change for what is offered.

I did 3500 boosted miles removed stock pistons and measured and were still in stock. Went to 6500 on second set and was still going.
This was a MTNTK setup. MTNTK with injector relocate or BD with secondary injectors or other kits with secondary will get more miles then say a Silber with a flash with injectors in stock location.

any specific reason why?
my mtntk axys and my neighbors sibler axys both 2017’s both lost compression at 1300miles. anyone else having cylinders/pistons go out of spec early?
Yes MTNTK relocates the fuel injectors and secondary injectors are in the charge box.
Stock injectors are in the cylinders so you don’t get the fuel for lubrication that you do with MTNTk or secondary injectors.
Think of the path of the fuel in stock location vs secondary injectors.
MTNTK new kit is using stock location I assume because some had starting issues with the old setup cold so hard to say I’d the kit will be as good as the old 800 for reliability my guess is no.
Did you measure pistons, cylinders, what oil and fuel ?
How much compression did it loose and were they ever over heated or any detonation ?
Fuel for lubrication.
Cool.
Does silber pushing injector oil through the dead end system so the entire intake tract is coated in oil not lubricate the entire engine? (In addition to all the Normal ports at a higher rate due to the reflash)
Asking for a friend.
Extra oil from ecu being turned up does help. Fuel also socks away heat. Most all
Of them will have some extra oil from the turbo. It’s hard to say how much puddles up vs makes it into the engine at a time but definitely doesn’t help as much as the extra fuel in my personal experience.
measured cylinders and they were good, pistons, had some wear, nothing detrimental didn’t measure those tho as at the time i was just concerned about cylinders. ran premium from good known source and Polaris ves . no over heat, no deto comp was down to 100pto 105 mag. neighbors sled did have out of round cylinders, flaking nicasil
