sorry i have so many posts on here for help with my blaster (if you have noticed i posted about 4 different problems in the last week) but i guess thats what the forum is for. everyone is telling me im running my blaster way too lean which im not doubting because i dont know a lot about motors just the basics and i would like to get my quad running well by doing it myself with the help of people on here. so my quad i thought was bored .60 over (which is what the kid told me) is actually bored .20 over because i checked it today. it has an fmf exhaust, 30mm mikuni carb (i dont know which one, i cant find it online), reed spacer, and im not running an air box just a uni pod filter with a velocity tube. when i got the quad the jetting was 250 main and 40 pilot and it would not idle because it was too rich. the kid gave me a 140 main jet and another 40 pilot jet and i put the 140 main jet in and it idles but everyone said it is wayyy too lean. what kind of jetting should i be running?
