I have an 04 Viper ER and the idle does seem to come back down to specs everytime. I've cleaned the power valves and adjusted them to about 3mm within yamaha specs. Is it possible I have a sticky one? I just bought the sled and the old owner didnt run yamalube, so I'm trying to run the old oil out then run yamalube. Is it better to run the valves on the tight side or loose side? Any feedback would be great help! Thanks fellow yammy riders!
