I have a 1996 Vulcan 800 Classic with about 37k on it. It has been having an issue with second gear for the past 6 months. It feels like something 'skips' or 'jerks' around shifting RPM's after shifting into second gear. I took it to the shop for a tune up and they told me it was the chain and sprockets. I changed the rear sprocket and chain and the skipping did not go away. I really do not want to take the engine out or crack the case open for no reason. Does anyone have any ideas as to what this would be? Thanks!
