Posting for buddy. Purchased a 1996 sporty with 5100 miles on it the bike started to run poorly took it into an indy and they said the valve was sticking replaced the valve and pushrods. The bike runs ok at times and at other times it has the same issue as before. Today, early morning it was cold he stated it up and it ran poorly again after a about 5 min it starts to fun good again. This also happens when the bike is hot. Any thoughts on what this could be if the valve was replaced?
