Drill bit size to jet # conversion chart

**BossMan** · 05-09-2008, 11:50 AM

Is there any way to make a chart that converts drill bit size to Main Jet size. I found THIS chart that gives the measurements of drill bits. Anyone know how to convert this to Jet size.

I want to ride this weekend & need a 178-180 jet. Installed a Muzzy on my brute & it's way lean. Just wondering so I dont have to sit on it all weekend & go Vrooooooom Vrooooooom

I think I just seen a chart on HL site that somebody posted in the brute and prairie section about a week ago, I knew I should have saved it.

there is a chart on here. drilling jets is i beleive how i found it. you will probable need numbered bits for a size that small.

You could also just try shimming the needles to get it close so you can ride.
