Picked up an HMF Sport Slip-on to be used with a Sparks foam filter, otherwise stock with the stock airbox lid.

155 main, 42 pilot and a small shim under the needle clip sound right to you guys? ... Or should I drop down just a bit (152 main/40 pilot) since I'm keeping the lid?

Elevation is about 700 feet and average temp will be 75, +/- 15 degrees, more or less...

Any help is appreciated...

I ran a 138 dj(155 k. i think), with 3 turns out on the f/a, 38 pilot, and the 3rd clip down at about 1000ft. I had my t-4 slip and a k&n on with the lid on so you should be in the ball park with what you are at. steve
