I have a ton of those "tool kit" wrenches, and probably over a dozen never used tool kits removed from bikes that were sold or traded.
Like I said before, there are a LOT of things about the Vulcan engine that don't make sense. It is an engineering nightmare. It may have been designed by several engineers who never communicated with each other, but I personally feel that it went through a lot of changes from the original design. I think it was originally intended to be chain drive, and was converted to shaft drive, which would explain the clunky front bevel gearcase. I also don't believe it was ever meant to be a cruiser engine, which could explain the hydraulic valves and lack of access to the stator. They may have used hydraulic valves because there would have been no way to get to the valves in the Vulcan frame. They just didn't care about the stator. It might also explain the convoluted intake system. Some think it may have originally been intended to be a sportbike engine. I remember a really old article from a magazine test back in the '80s that said it was "a Ferrari engine in a chopped and channeled '50 Mercury coupe" It certainly is an oddball design for a cruiser engine. All other cruiser v-twins are a lot simpler, and make most of their power down low. The Vulcan 750 make it's best power near redline, which explains the four cams, four valves per cylinder, four plugs, two carbs, and super short stroke. But I also find it odd that they used a single crankpin and added a counterbalance instead of using staggered crankpins. While not most cruiser riders cup of tea, it is this characteristic that makes it so good at high speed long distance highway cruising, and so smooth and comfortable at highway speeds. It's like a sport touring bike (which always seemed like an oxymoron to me) that actually has a comfortable riding position. However the Vulcan engine wound up the way it did will probably always remain an enigma.
