Thought I'd ask here first. Just got my 08 heritage back from its 5000mi service. Right away I noticed shifting was amazingly smoother, but now it seems like it lost the getup and go it had in 5th and 6th gear. Before when cruising at 60 or so I could twist the throttle and get 20mph more right now. Now after the service its not there. Work order states air filter and spark plugs as only engine work. Any input would be greatly appreciated,thanks Ruley
