Over the winter I've switched from an HMF slip-on to an LRD fullsystem, installed a cam, and honed the cylinder for new rings. No lid, K&N, 440 (89mm) ross piston, 11.2:1, and Hotcam stage II. I was running a 165DJ main with the HMF and quiet core and 50/50 race and premium. How many sizes should I go on the main? One notch richer on the needle?
