got the bike fixed now its running ok it pulls well in every gear but feels flat bottom end the air box has holes drilled in it not sure if this is helping things everything else is std apart from hrc stuffers in the reed blocks

has anyone else drilled the box is this a mod you guys do?? i know people do it on four stroke enduro bikes but im not sure about 2 strokes,i do know my way around a bike just not ever played with an nsr 250 this being my first one

can anyone give me a good starting point im running 2 turns out on the air screw and *** mains i didnt want to touch the needles in case i split the gasket (did that on my 3ma)

im going to gaffer tape up the holes and try it like that if it makes it better i will fill them in for good just need some time to play

thanks in advance jody
