Hey ProX, those round main jets you are looking for are also known as N100/604 jets, the hex type are also known as 4/042. Just for your info and they are way different, so don't ever think of using a round type in place of a hex type, or vice versa. Down around 90 they flow the same, but 150 round jet flows is the same as a 275 hex jet, and a 170 round jet flows the same as a 370 hex jet. So from that you can see someone would be in big doodoo if they thought they were the same. [img]i/expressions/face-icon-small-smile.gif[/img]

 

When that was first said I think that was the heat of the keypad talking.

You are using this now much in the same way I was when Originally posted by: airraptor

I played around with that for awhile then I dropped it.

Thanks NCScrambler. I just installed a 160 main but didn't move the needle position yet. I think I'm going move the clip one positions down (bringing the needle up one notch). I'm still with just the K&N and WB Slip-on, but just jumping on it in first gear its a lot more snappy on top end!
