its weird, it feels like my kh125 at the top end which was dyno'd at 15hpbut it has no where near the pulling power down low,i think im going to swap the carbs back to the stock set up but use the floats and float needle.and replace all the jets with stock sized ones.i was reading the http://www.mikuni.com/pdf/vmmanual.pdfand it explained the whole small main with big pilot jet conundrum with these new carbs,and basically points to the needle as a possible place to start looking.well thats the way i read it, 2 stroke tuning = dark art
