Hey, finally a SLC person. I did the shave last weekend. I put 140/40 main/slow and one shim with 2 1/2 turns on the mixture screws. I feel like I'm dumping gas in there, but my plugs look good after about 100 miles, so I'm going to stick with it. I'm sure you can get away with the stock slow and a 138 main, maybe just add a shim or two to the needles. I've got a bunch of spare needle shims, and I'm local, you can have 4 of them if you're close enough to justify the drive.
