stalling-some times
 

when I ride wide open for maybe 20-30 seconds my 2t will act like its running out of gas.i checked all my lines no leaks.i drilled some holes in the gas cap no good.i also replaced the fuel petcock and still it will shut down unless I let off on the gas,then I can usualy get it going again.i need a auto enrichener but I doubt that would effect whats going on.it runs great and has a brown plug so what could cause this?

I think you need to adjust the floating height in your carburetor. It sounds to me like it's to low, and you that way empty your carburetor for fuel when driving.
Take your carburetor off, take the floating bowl off, turn it upside down and put a piece of tube /fuel line, and mount in on you carb. Then blow in it and lift the floater with your fingers, there should be open almost right away. If not, adjust the small clip that holds the needle in place.
Kind regards

ok thanks ill try that
