he had scoops, oversized oil filter, bigger valves, larger pistons, and a bunch of other stuff to lower the temp

Yea i bet the 440 kits biggest problem is that they over heat !!!! to get to 500 your gonna be stroking it and a huge bore !!! CK 1999 is the guy to ask !! on a 450R your runnin a +3 crank and 100mm bore and big time head work comes out to 511 or so !!

Ya the kit came with bigger pistons stroked cam crank and a bunch of other stuff.... oh and so basically bottom line is keepin it from overheating if you can do tht the bore kits in general arent to big of an issue

      Anyone use Niche parts?
      By Charlesbrown
      I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred.  Anyone have experience with Niche or similar Chinese companies?

      Have you ever purchased a quad from an impound auction?
      By DarkRider
      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      2016 Arctic Cat 500 Oil Leak
      By alexwv1863
      I have a 2016 Arctic Cat 500 and recently noticed some oil leaking on the engine block to the right of the oil filter. It's near two metal lines going in and out of the engine block. I think one of the lines is called an engine oil line. I have a photo I'm going to try and attach. Any help would be greatly appreciated. I don't want to start tearing into the engine if I don't have to. I think maybe a gasket or something blew around one of these lines. The ATV runs fine otherwise. Doesn't overheat or anything.

      bearing and seal replacement questions for 2005 Scrambler 500
      By p5200
      Hello, what is the best method for installing bearings into their race? I've set one in place and tapped it down until it was metal on metal. Is that sufficient? Surely it's not supposed to go into the race until flush? Also. does the coil spring on the seal go into carrier bearing housing not facing out? Thanks! 🙂 Seal goes in until flush correct?
