2012 PRO motor issues

[SLC]

Now that's funny!

Now, that's funny!

Or...
Slip on un-laced boots, bathrobe and Cousin Eddie hat, go outside, slow-pull recoil to turn over cylinders a couple times, start sled and go back inside and get dressed. (You may, or may not, need to hover by the woodstove for a few minutes until your nuts drop back down)

While you're gearing up the sled will come to temp and after idling at 125 for a few minutes, shut itself off.

My 2012 blew up at 1400 miles. I babied it from new, turned up the oiler, mixed some oil in every tank of fuel, always warmed it up and never took off before temps stabilized. Ran the chevron 94 fuel from the same place every ride for 2 yrs. I used amsoil interceptor oil. Dropped a piston skirt into the bottom and blew a hole out the crankcase. They warrantied the motor and dropped a whole new one in but I had to wait almost a month because polaris had them on back order......which tells me they are going through alot of motors! I am a mechanic by trade and have raced everything from bikes to cars to karts with my sons. I was overly fussy with the reputation of the polaris motor but to no avail. Checked my pistons and cyl's with a fibre scope thru the top and pulled the pipe and manifild to look at the skirt as far as possible 2 times a year.

Some motors seem to last but with polaris i think most are prone to piston problems. Luck of the draw i guess.

What makes me the most upset is that I love the chassis and clutching of the pro the most of all the manufacturers, but the motor is a letdown when you look at the fact that stock it puts out almost 15hp less than the other 2 (CAT AND DOO) and it is the least reliable by far. Cat and doo have way less failures AND put out more power! Sucks to have to spend money just to get up to the same power level the others have stock.

1600 miles on my 12. I put new pistons in at 600 miles and ported it with a head. 1000 miles of trouble free riding last season. Im doing another new top end on it now. Will be the 3rd set of pistons in it. Love this sled...new pistons every year is cheap insurance to ease the mind if ya ask me.
