1993 2×4 250 trail boss

Hey guys, I bought this atv about a year ago, I rebuilt the carb, ran new lines and got tires for it. I also rebuilt the rear caliper and got new pads. Everything works great except my pvt belt keeps slipping. When I got the four wheeler, the pvt case had a big whole in the bottom, I felt underneath and my drive pulley is protruding through the case like something’s bent or crooked. Just confused why it slips though, nothing hits the belt or the pulleys. Give me your thoughts

battery upgrade to drycell type ?

anybody do it and recommendations ?
did a search but did not find answers -

want to avoid the deep boonies - stop shut down and no start situations
figure a upgrade will help -
and carry a boost pack

Making dps work without signal from speedometer

So in some country's where ATV are not allowed to go faster than 40km/h some people cut wire 18 from the speedometer, it cuts the signal from the speedometer to the engine so the ATV goes 105 km/h, but this also cuts the signal from speedometer to the DPS so the DPS don't know what mode its in so the DPS don't work. Anyone knows how to make the DPS work without signal from speedometer?

Oil line specs?

Anyone know the size of line to use to replace the oil line on a 1986 250? I'm looking at all the parts diagrams and none of them show this. I think the previous owner took off the injection oil and i'd like to put it back....

Polaris Factory Authorized Clearance 2018

I understand this is coming up. Any word on when it starts?

Any thoughts on how these new dollars from the factory will compare to the rebates they are offering now?

FWIW, I'm looking to purchase a 2018 Sportsman X2.

570 Outlander max tire size question

I recently ordered 2 27-10-12 tires(buying 2 at a time so I can afford them). I’m not really sure whether to get 27-8-12 for the front now or 27-12-12 for the rear. They are Wanda big horn knock offs. Also, my right front tire is worn a lot worse than left front. There doesn’t seem to be any play in the wheels and it looks like it’s lined up to me but it could be off. Anyone else have that happen? Thanks for the input fellas
