when you are like in 2nd or 3rd gear it seems to just sputter out and die. (thats what my bro in law says, hes the last to ride it)

i was gonna yank the carb and double check that. but before i d i thought of this.

it has a fmf pipe and several holes in the airboxlid with a uni filter. does it just need to be rejetted you think? i dont think it was doing this before i put the holes in the lid.

thanks.

Raise the needle one spot (clip down), and go up a 3 sizes on the main jet. That should give you a decent start.

I've taken the airbox lid off of my 250ex and had no problems. Something else is causing your problem
