I hope someone out there can help me with this one. I recently installed the Hot Cams exhaust cam in my 426. Bike fired right up and ran like a champ. However, once the bike is up to op temp, I can not get it to idle and it is extremely rich (plug is black and sooty). It either idles very high or stalls. I've tried going leaner on both the pilot and main with no luck. I have rechecked the timing and valve clearances several times and everything seems to be spot on. One other notable item, once the bike is warm, it WILL NOT start until the hot start is pulled, then it fires up with one easy kick. Is it possible that one of the slow air circuits being plugged or dirty could be causing this? I'm at a loss here, any imputes would be greatly appreciated.
