Hey Guys, I am posting this for a freind to try and figure this out cause I sure as hell can't. He has (2) 2005 Indy classics that do the same thing and we can't figure it out. They will start and idle just fine. At first when they started acting up you could go maybe 3-10 miles and then it would bog down you couldn't get it to take any gas, like it was fouling plugs but that wasn't the case.. You could lift up the track and it would spin, but not under load. I have gone through the carbs both indoors and out in the field. Both were very clean, even checked the piolt jets and main jets. Since this is happening to both machines I feel that it is not fuel related. You can rev them up but it just won't accelerate. Now it does right from the get go, not just after you had been riding it for a while. It progressively got worse. I'm sure I am thinking about this too hard and it right there in front of me. Any ideas would surely be appreciated.
