Yes I know I'm crazy. I was wondering if the 750 motor is used in any other bikes that would have the shift lever come out of the cover that has the site glass window for the oil. Mine is stuck in 2nd gear and the motor has to be split to fix it. I'm not lucky enough to have it be something bent or worn out like a lot of you had happen. This is a threaded rod internally that must have broke.
In a word, no. The vulcan 750 engine is completely unique, and was never used in anything else. There are a lot of questions and mysteries surrounding it's unusual design, and it appears to have undergone a number of "quick and dirty" design changes before reaching it's final form. It is obviously not well thought out as far as working on it goes, and many parts seem like afterthoughts. It is generally thought that it was first designed for some type of sportbike, with chain drive, and a totally different frame.
If you have issues that would require splitting the cases, and are not a top notch mechanic with a lot of time and patience, I would recommending looking for another engine. The VN750 engine is a mechanics nightmare. As far as I know, there are only a couple of people on this forum that have successfully rebuilt one. Jerry.
