Deep water turned off wheeler

Good day!! Here we go.

Went through deep water on stock 2014- 850 xp ho. Wheeler stalled so I winched my self out. Stood it up on back end and drained water from exhaust and cvt plug. Cvt was right full of water, and exhaust not so much, thank god. Checked oil and seems to be fine for level and colour. Water was up to back end of seat with front end up higher so there was no chance of air box and cvt intake taking on water.After a good 10 min on its back end, she stated up like a champ and has been fine so far. I didn't mean to go that deep as we all try not to being stock but hey, it was fun after the fact of realizing I didn't just total the engine. Question- is there any device like a check valve on exhaust system to prevent water back into engine? And should I rinse out cvt housing? If so, how? Water i went through wasn't that thick muddy stuff but it also wasn't clear. Also is there anything else i should check for water? As for stalling I'm sure dielectric stuff would help on spark plugs but I think if I gave more Gass I would have made it through. Hope someone can help!! Thanks lads!!

2004 sportsman 400 running problem

I have a 2004 sportsman 400, was using it the other day around the yard and out of nowhere it died. Would not restart until i turned the key off and back on again. Now it will sit and idle forever perfectly. As soon as you touch the throttle it dies. Got frustrated and put it in the garage for a few days. Went out today started it up and it ran fine again. Drove it around for a while all seemed good. Then it did it again. I have had the cover off and verified that the throttle safty switch contacts are not touching when pressing the throttle and have held them apart while pressing throttle and it still dies. Carbs are ruled out as it ran perfect for about 20 mins today until the problem presented itself again. Battery conections are tight and is showing 13.2 volts at rest with key off and im getting 14.5-14.8 at idle at the battery. Anyone have any segestions? Im beginnig to think ecm as once it dies it wont restart until you cycle the key off and on. Is there any way to check the ecm?

Xpedition 425 AWD Questions

My Xpedition had the front prop shaft removed when I purchased it due to a bad ujoint. Also, the override switch and the AWD selector switch may or may not be working. I have a lot of testing to do. The Xpedition is a manual 5 speed model so I do not know if that will effect the AWD questions. I would like to test everything before I put the prop shaft back on, but I need a better understanding of how the Polaris AWD system works.

The front output shaft spins when it is in 2x4 or AWD. The override switch does not seem to change anything. Is it normal for the output shaft to still turn while in 2x4? I appreciate any info. Thanks

Tire Size VS Speed Loss Question

I just bought a brand new 2017 450HO and I dearly need to upgrade wheels and tires. If I go to a 26" tire, am I going to lose a ton of speed or power or will it be ok? Also, any need for a clutch kit at this size?

Where to buy wheels and tires?

Hay all!! I just bought a new 2017 450HO in Velocity Blue last week and I have realized quickly that I need new tires and wheels ASAP! The stockers are junk for my style of enjoyment. Either way, where do you all recommend shopping for wheels and tires online? So far it seems like Mud-throwers and Rocky Mountain is what keeps popping up but I am just wondering if there are others better or reviews for wither of these places.

Thanks a bunch!
