Just traded an 83 Honda Shadow for a 85 VN750, but haven't fired it up yet. It leaks oil where the rod that the shifter lever is bolted to exits the engine. Is this a quick fix or does it require dismantling the engine? Also, when I work the shift lever with my foot, it only goes into two positions, lifting it up lets the bike roll (I assume neutral) but no matter how many times I rock the bike back and forth it only clicks down one time. I don't know where to start ... is this a transmission problem? Any suggestions what I should do?
