Hey everyone, first off I'm new here. I'm looking for some advice on an engine problem I'm having with my 86 GL1200. From idle to about 2500rpm the engine stumbles and has little power, I have to feather the clutch alot to get her going. After 2500 rpm, she comes to life as always and runs awesome! I've put fuel cleaner through it and changed the plugs. Any reccomendations?
