I have s 2016 Polaris sportsman 570, radiator was relocated last year and road all summer with no problems. In the last few days I can ride about 10 minutes before it overheats and goes into limp mode. The engine is really hot the radiator lines are kind of hot b it the radiator itself is still really cool, fan does cut on after about 5 mins of riding. Any help would be greatly appreciated!!!!!
Direction of tire mounting
Bought a couple of new inexpensive WANDA Sport ATV P348-10063 GNCC Race tires for the fronts on an old Polaris Express 400 2X4 I picked up last spring. They have no directional arrow on them but the tread pattern suggests to me a preferential mounting.
As said, these are front tires on a 2X4, so drive traction is not the issue but turning traction is. See the pic, ignore the ratchet strap (mounting them myself), but note the red stripe on one side as I will use that for referencing.
Unless I hear convincing opposing opinions, my intention is to mount the tires with the red striped outer knobs towards the outside on the left side and towards the inside on the right side. My opinion is based on having the full side of the "underarmor" logo-shaped knob providing bite into the road surface on turns, whereas mounting them the opposite way, puts only one corner of the knob into the lead biting edge on turns. I think this would provide better turning traction. OPINIONS??
I think this would be in line with having a VEE patterned tread pointing downward on the the leading surface of the tire. Is there any significance to the red stripe??

New power out of old machine
I have a 2000 xpedition 325 4x4. I’ve had the atv for several years and before that my grandpa had bought it brand new in 2000. The atv runs and drives ok still. Wanting to make it an aggressive mud only atv.
The research I have done on it tells me there isn’t many options for the 325 performance wise. But the 425 xpedition I have heard you can bolt a 2000 500 sportsman/scrambler jug, piston, and head assembly right up to it.
I found a used 425 xpedition bottom end and am considering boring out a 500 jug with a bigger piston. How much do the 500 guys usually bore out and where do you get the pistons from for it?
Or do you think I should keep a standard 500 bore and just port and polish the head?
My other concern is that the 425 only has a 70mm stroke while the 500’s have a 75mm stroke. Will this interfere with anything? Seems to be working for other guys that have done this mod.
Thanks in advance for any info!
