I have a snorkeled out 07 brute 750.. exhaust.. clutch.. 29.5 outlaws.. My problem is... when riding it runs great until i use the last quarter of the throttle.. when i give it all the throttle is breaks up and i have to actually give it less throttle for it to work.. oh and i have the worlds worst idle.. it pretty much just turns off at a idle.. any suggestions? i live in the daytona beach area and wouldnt mind paying someone to help..

U deff need jetting help. First crack the cover on the air filter and see if your starving it for air. You may be running rich. Pull the seat off and pop the clips that hold down the filter cover. put a pencil or somthing in the bottom groove so the cover won't fit back tight and air can get in through the sides. Crank it up and see if it runs better or worse. I had to make mods to mine to get it breathing right. More than likely with your snorles you are staving it for air. U may have to pick up on the breather lid more than a pencil and see if it gets even better.

Try like Slumlord says. Also, with it dieing at idle, that's a sign if very low float levels. That needs checked as well as your fuel delivery system and the screen in the tank. If you run it easy and it doesn't try to dies at idle as much but after you suck all the gas out of the carbs by runnung it hard and it always dies when returning to idle, that's a sign of weak delivery.

Like Slumlord says, you can crack the box lid and put something to make it get a little more air to see if leaning it helps, if not, then seal it back up, and use some duct tape over the snorkle...about a quarter or less..to see if richening it up helps. Do know that richening it will use more fuel, and if the problem is low float levels or weak delivery, she will probably try to die worse at WOT.
