Polaris Predator 500

So my front hub broke, I’d like to put aftermarket on. Hard to find new oe ones. Please help. I’m new to all of this, I have some car knowledge and try to apply it

Hello. I got this fourwheeler to fix for my buddy. It wasnt starting at all when I got it so I opened the valve cover up and checked the timing and the timing was way off. I set the timing bolted all back together and it started. It only stays running with very little throttle applied. There is a weird noise coming from the engine and it smells like its burning and also smokes from the headers. I posted a video idk how helpful it will be but I need some advice on the next step. I want to say it's the piston and rings, but I'm not too sure was also thinking something was up with the valves. Thought I would get some advice before trying anything. Thanks!
 
 

Hi there , have a KAZUMA 500 JAGUAR the rear diff is permanently locked , how can I get it out of lock just about tried everything I think, ?? .  Thank you your help is appreciated.
 

i have a 2001 suzuki quadmaster 500 4x4 that the primary cvt clutch is rusted on any ideas on how to get it off i want to try to reuse it if possible.

I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.
