I have recently purchased an '85 VN700 and an '83 Vulcan 750 for a total of $150. The VN700 had some internal engine damage and I need to replace the upper and lower gasket sets, right counterbalance and gear with spacer and gromets. are any of these useable off the '83 Vulcan 750? I had heard that the bottom of the two engines were the same but I wanted another opinion. Thank you and I'm glad to be a part of the forums!
