jetting problem i think

[redneckwheeler]

i have a 400ex and i bought a cutis sparks pipe a dyno jet kit and a hot cam stage 2. when i put it all in i used a 170 main jet and it was miss firing sometimes aand boggin if i hit throttle from almost idle. so i switch to a 165 and know my quad wont even start sometimes. if anyone has any ideas what i need to do please let me know. thanks joe

do a search.:o but the main jet isnt gonna affect starting or goin from idle. you gotta richen up the pilot and needle.;)
