Question about 2007 HM CRE F490X I
First time to post hope im doin it right. i have a 76 CRE. starts first kick idles fine
Fast as hell but when its warmed up and i slow down or stop i get a popping noise sometimes its a low rumble popping some times it really pops loud. adjusted valvestiming is dead on already cleaned carbs and gaped and installed new plugs.still pops but only when good and warm. one thing i find strange is that the #4 cylinder runs 100 degrees cooler than the rest. i found this out by holding a handheld gauge at the same distance from all 4 of my pipes. i am really lost here any help would be greatd say the cool cylinder is running richer that the other three. Lean mixtures will pop when deaccelerating. Make sure all four carbs have the same main jets and intermediate jets with the needles set the same.,,,
