I was riding today and all of a sudden when I tried to WOT or even 3/4 throttle I had no power. It sounded like I had the air filter lid off. I could let off the gas and it would run fine as long as I didn't 3/4 to WOT. ANybody have any ideas. It ran great for about 45 minutes then poof. Anybody?

 

Piece of dirt or crud, got sucked into the main jet, and is now blocking it?

 

be aware of carb sliders getting groves in em... I don't think you have enough miles/hours yet. Could be gas etc...
