Went on a 6 day ride in WV and on last day one of the riders 2010 Sprtsman 550 just shut down at almost the end of the ride.Started back up for a short period and then nothing..The motor seems to be locked up..All the water is gone from radiator but none is out of the overflow jug..Checked dipstick and that is where the coolant ended up..It is now at the dealers (Bairs Inc.) They seem to think the headgasket or cracked block..Anyone else experinced this ???It has extended warrenty..

 

Don,t see much post about it. Hope its just a fluke and only a head gasket.

 

I have a 2010 sportsman 550 X2 and I can say its been running fine. I haven't heard about much problems with the Polaris 550 motor....yet

 

Please keep us posted. Hope it is a fluke, glad to hear you have e tended warranty.

 

Broken rod and busted cylinder..Have to replace the complete motor...

 

Did you have extended warranty?

 

Yes there is extended warrenty...The estamited cost by dealer is 3300.00 dollars..Sure seems high for a short block ????????????

 

Dealers price is cheaper than if you'd have to purchase it out right without the warranty!Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse

 

Wow, that sucks. Gonna go check my oil and coolant level right now.

 

Kind of stuck with the 550 because they have not been out for long so finding a used motor off E-bay from a parted out ATV would of been hard.

If a Sportsman 500 blew a motor you could go buy a complete running ATV for less then $3300 let alone just the motor.
