Hello,

Im new to the forum but I thought I might give this a shot.
05 Sportsman 700 carberated model. starts and idles fine. Drive for about a 1/4 mile runs smooth then it starts acting up. Will bogg and only go 20 mph top speed. engine sounds like when you remove the airfilter and run the engine. just had fresh tune up .plugs, oil/filter air filter changed. changed both carb boots. Its getting cold up here and i just noticed today it blows white smoke out of the exaust manifold right by the header when it misfires. I also cant figure out how to drain the float bowl. any explainations would be great!! thanks!

maybeneeds a new donut gasket at exhaust manifold, does it have the one with springs holding it?. might also be breather tube from back of cylinder to air box, does it have the white filter in the line? If so there is a recall that will give you a new vent line, the filters would freeze from condensation and crack causing a vacume leak
