Hello, looking for a little help. I just bought a 09 rap 700r. It seems to have a idle issue. When i start it up, it seems to run fine...kinda high on idle,but most do. When i blip the throttle....the idle will go way down and almost die. And sometimes it does die. Start it back up...runs fine...and repeat agian. The bike seems to run fine going through the gears.....just idle. It almost seems like a vacuum leak....or TPS adjustment??. Any thoughts....am i on the right track?
