I'm going to put in 58/165 jets in my 05 650L so it runs better with aftermarket exhaust, uncorking, etc. (Right now I have 55/158 and it leans out at 70-75 mph or so.) But I see Keihin jets that go WAY WAY bigger than that. Are any of you running bigger jets than 58/165? If so, what mods have you done?
