[candiria05]

hey i have a 06 blaster with a DMC Alien header and silencer and a k&n air filter im useing a 140 main jet in it right now, what should i be using? and what kind of power increase will i get?

140, i hope that was a typo thats waaaaaaaaay lean. did you mean 240?

[candiria05]

yeah i ment 240

[ajh97blaster]

from what i've read on this site. a good jet to begin with is 270, if its too rich bring it down to the 260. alot of the instructions from pipes should have some info, if not just ask more questions theres tons of us willing to help a fellow rider out

right on, i'd say 260-270, pull that airbox lid off too, more air=more power, it also helps with an a/m exhaust, you have the ability to let more exhaust out...let more air in.
if you havent jetted it yet, stop riding it, lean jetting causes melted pistons and possible siezed cranks.

Depends on the riding situation for the removal of airbox lids. If your in water or real muddy areas a lot, you shoud go with an Outerwears airbox lid from the research I've done, simply because it allows way more air in than stock, but then again a little less than with no airbox lid, but it will be much safer in the muddy areas.
