Hi peeps, my bike won't idle well, above 1500 rpm and throughout rev range it runs fine, the carbs have been ultrasonically cleaned, float level checked, balanced, and run carb cleaner in the petrol several times. Still doesn't idle as it should. Replaced ignition coils, leads, and pickup coils, compression fine. Starts and seems to be charging ok. Anyone had this problem and found a cure? Any help most welcome.
