I have a 1991 fatboy that starts up...runs strong then after about 30 mins of riding will start to bog like the choke is open, then after it sits about 15 20 mins. it runs fine, then same thing almost at the same time and miles. Does anybody have any clue? I'm thinking maybe the ignition is overheating? the bike just sputters...I rode the bike to a friends 2 times and it happend in almost the same spot same miles and time frame.
I sit chill...start up all good like nothing....I also noticed at higher RPMS it will sometimes sputter.
