Im 100% new the forums, so, hello! Ive recently gotten a 1989 and honestly immediately fell in love. Got the duel carbs you know, quick on its feet starts up and runs fine but every once in a while it goes wonky and when i give it throttle it sputters rapidly. I can key it off and coast for like 20 seconds and turn it back on and its good to go. Im absolutely lost, anybody have ideas? Vapor locking from the heat? Plugged fuel filters or gunked carbed? Im going to give it a tune up tomorrow and see how it goes. Any responses are appreciated.
