Did a chop today and finally got it!!! 340s and its about 63F out. I was discouraged til I finally took the time to cut the threads off the plug. Thought Id be able to see color from the top but I was wrong. Tan and about 2mm tall,( not as oily as your pics, booker) I'm satisfied. I know this will be a bit rich in the upper eighties and nineties, but if it rips anything like it does now, I should be able to hang with my buddies 4X4s on the trail. Still doesnt have any low end power, none to speak of til I get on the mains. Pilots? Air screws? Live with it? How many HP are ssts and a K&N good for? I almost soiled myself WOT in sixth! I did go one tooth larger in the front and one smaller in the rear for gas mileage on trail rides, but I guess going up 14 sizes on my main will wipe that out and then some. Thanks for all the help so far guys, I owe you all a beer or three! :baseball_w00t:
