Came here for help, If it’s in the wrong place I’ll move. I’ve got a 2000 model Polaris Magnum 500 that runs strong as can be for about 25 mins until warm, then sputters and loses power. Took it to a shop and they say it’s low compression and they will have to swap the entire engine. Seems a bit much and costs more than the entire bike. Was wondering if anyone has seen this and what the fix was. When I hear compression I think of gaskets, not an entire engine. Seems like if it was that bad it wouldn’t have power cold. I’m at a loss. Any help is appreciated greatly.

I have a 98 Polaris Magnum 425. Runs GREAT for 10 minutes then starts to load up (sounds rich) and looses power. Final;ly just stalls out on idle. If it sits 20 minutes will run again.
replaced fuel, added fuel treatment (seafoam), Replaced plug (carbon fouled), plug wires, air and fuel filter, checked all fuel and vac hoses, REPLACED carb with new. Still no good. Just ordered a coil, not sure if that will help
Note: both the new and old carb only had the idel adjuster screw - cant find the jet adjustments or air/fuel mix screws so I cannot say how they are set.
Looking for ideas short of spending big $$ on Polaris service
Need help with a 2007 polaris phoenix 200 no spark new cdi,new ignition coil,checked resistance on pulse coil and stator,not getting power to start button now guessing the solenoide went in all the testing not sure.also have three ground wires to battery is this normal or..?
