2007 Yamaha Wolverine 450 idling issues

I bought this atv this year and ran fine ever since this past weekend when I took it up to this ATV park in Tennessee, I started out on this trail and the Wolverine started to lose all power like it had bad gas. I went back down the hill and everything seemed to run ok when I made it to the top it started to get all sluggish again, we put this fuel additive and ran a lil better but would crap out here and there. Then after like 10 min it ran fine for like a good hour then went back to being sluggish, it idles fine and with partial idle but full throttle it loses all RPM's. I dumped the gas out and added new gas, sprayed carb cleaner down the throat...I'm thinking a stuck or dirty jet, anyone have any opinions?

      What's the best kids atv out there? I've seen everything from the ones released by the major manufacturers to all those knock offs. Kawasaki has a KFX 50 that is pretty nice for under $1800...

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      Anyone purchase or check out Rockymtnatv lately? Well I was just browsing over there and they have a pretty cool section called Ten Dollars Or Less. Some interesting things to check out if you are in the market.

      My 2014 750 king quad stalls sometimes when I touch or turn the handlebars,the problem has gotten worse,my machine has 475 miles and is only trail ridden,I have a new factory battery and i have 14.2 volts when the quad is running and 13.3 on the battery when not running,also using a multimeter there is no change in volts when turning the bars until it does stall,If I pull the 40 amp power steering fuse it will not stall.......I've been told its the ECU,Hate to buy one if thats not the problem,but its kinda leaning towards that,,,,,need some opinions.

      My friends KQ 300 starts fine and runs, as soon as you put it in gear and try to accelerate its bucks and farts like crazy, not moving... I cleaned carb and it worked good for 1 day... now back to same problem.... could it be such as a bent valve????
