Hi,

I have a 2000 Blaster with a FMF fatty pipe and a power core 2 , also K&n twin air filter and drilled air box cover. I live in Mass. so the temp varies (this time of year anywhere between 55-80)
main jet = #250 - needle on the 3rd notch - air screw at 1 2/3 turns. Its running the best its ever has.

I wanted to take a survey of how people have their Blaster jetted for comparison. The format is below for three blasters I have and 1 for a friend.

'96 with all stock, bored out .020 rides around sea level, 80-90 degrees air temp runs very well, smooth acceleration particularly at low end. Recently ran at 6000 ft elevation 85 degrees air temp very well without jetting changes. Main = 240, Needle position = 3.

'96 with Paul Turner pipe and fat boy, bored out .020, rides around sea level, 80-90 degrees air temp runs strong, but better at mid to high RPM. Recent trip to 6000 ft elevation 85 degrees air temp, would not run without removing air box cover. Main = 250, Needle position = 3.

'97 with Trinity pipe and exhaust and K&N with outwears, no airbox cover. rides sea level, 80-90 degrees, originally very boggy with main = 330. Rejetted main = 290, runs better, maybe slightly rich.

'88 with unknown pipe upgrade, and UNI dual air filter drilled air box cover. Rides at sea level, 80-90 degrees, runs slightly rich with main jet = 260. Acceleration is a little sluggish. Needle at position 5 (rich) probably should be at 3 or 4.
