    It idles high when first started, then after a ride for 5 minutes it wont idle at all. could it be a vacuum leak? 3 of the spark plugs indicate that the carb is perfectly asjusted, the forth is fouled, it could be with gas or oil. I will readjust the carbs. thanks

    It could very well be a tight valve or two. That's a classic symptom.

    As has already been suggested to you in your other threads; YOU NEED TO CHECK YOUR VALVE CLEARANCES.

    PRIOR to carb tuning.
