I hate to say it, But I predicted what the future of this motor would be….. And like clock work it’s all unfolding exactly how I figured it would……. And how the cylinder finish, and the PTO-End design should allow.
Its strange to me, the 850 is such a great motor…. Much better in so many ways then all the 800 motors ever built 2008 thru till the end.
Yet the 850 is plagued with a few flaws that are so easy to fix, I posted the in December of the 2018
i pointed them out for all to see, and none of them were addressed in the following 3 years.
The changes Polaris made to get 40cc’s out the 850 motor in 2019 were absolutely brilliant to say the least.
Robbing crankshaft length out of the Mag end on moving it to the center of the crankshaft is so brilliant I cannot hardly explain it.
The Motor mounts are also brillant.
i say this next statement as simply a fact nothing more….. ( We do not need to reach for work Indy Specialty has plenty of work. )
Statement is - All production 850 motors should be removed from the chassis pulled down when they are New and the cylinder finish should be fixed, and the PTO-end of the crankshaft should be replaced with our New Custom Built 40mm PTO-End And Bearing upgrades.
if those steps are taken the 850 is as close to Bullet proof as any modern 850 built today.
I.E. - The 2022 Fuel pumps, and the 2022 Cooling system with the short tunnel is a whole other train wreck.
The 2023 Most likely will completely resigned cooling system ….. the short cooler is a engineering failure.
This spring riding season ( EVERY ) 2022 Polaris Mountain will over heat to level never seen before.
And if your not careful they will most likely VOID every warranty on very sled if Polaris wants to be a Dick about it.
Temps way past 200 degrees will common daily conversation….. and these big numbers will be a bad deal come warranty claim time.
