I need help making my predator 500 faster

Recommended Posts

hi i have a 2007 polaris predator 500. it currently has.

-trinity stage 4 exhaust

-170 main jet

-15 tooth front sprocked (for more topend)

-shaved front fenders.

i just do NOT get it. i clocked it and it redlines at only 78mph. i want to do over 80 but still have good acceleration and be within a budget. can anybody have any suggestions of what else i should do?

78mph isn't bad considering you don't have alot done to it, and most other sport quads don't go any faster than that without a good bit of money dumped into them. 80mph without just gearing it up will take a few bucks. A good bigbore kit may give you the extra grunt you need to properly pull the tall gearing you are already running, that will probably get you over 80mph.

That would probably do it too, depending on how much over-rev you get, you may even be able to get your low end back by dropping your front sprocket down to stock size and still be able to stay over 80 on the top end.

Most CDI boxes increase the rev about 800 to 1000 RPM's. An increase of 1000 RPM's on the Rhino without a more aggressive cam put the top speed from 42 to 51mph. JUST CHANGING THE CDI.

      doesn't idle at times but sometimes when it does as soon as I touch the throttle it just shuts off, what could possibly be the problem? I thank you very much for any help, Thanks.

      My father-in-law gave my boy a 1999 350 Big Bear. It's been sitting in a barn for a bunch of years. It runs great! My boy has been riding a couple weeks now and it has developed a squeal coming from the front end when you get off the gas at speed. No noise during acceleration. At first I thought brakes. I took it for a ride and I don't think it is the brakes. I feel it is the front prop shaft U-joints, front differential or one/both axles. I pulled the fill plug on the differential and I can't find anywhere how much gear oil should be in there. My gut says up to the fill opening. It doesn't have a manual. It's wet in there, just don't see any gear oil.

      #1 Should I fill the differential with gear oil up to the fill opening?

      #2 How do I check or know if the u-joints are bad? That looks like a "Big Bear" of a job if they don't need to be replaced.

      #3 What else could it be? I don't think it is the front bearings. I jacked the front wheels off ground and no play in the right wheel. Very little play in the left wheel, looks like the lower control bushing is where that play is coming from. The rubber CV boots look original but all still intact. Wheels spin easily without any noise.

      Thanks for any help!

      If you're getting that pesky leaky seal on the pinion of your front differential and the pinion has allot of play, polaris won't sell the bushing needed to repair it properly without having to shell out big bucks for the complete ring and pinion kit. 
      I have a kit with an upgraded bushing, Japanese made bearing and USmade seal
      50 shipped in the US and 55 to Canada

      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.
