Wow, Buck, I'd be curious to learn why you traded a Wing for a VN750......
With that said, I think you'll find the basic engine in the VN750 to be as reliable as anything else out there--provided you do the oil changes as you should, and other required maintenance. Stay away from motor oils labeled as "energy-conserving"!!!!!!!!
The VN750 is one of the few cruisers (or bikes!) that has self-adjusting lifters, a centerstand, shaft-drive, tubeless tires, along with complete instrumentation (fuel gauge, tach, etc). It's designed to be as low-maintenance as possible, and as easy to live with as anything else out there.
Some VN750s have an issue with the stator (and so do many other bikes)--but you can search around inside this forum for ways to extend stator life, or get around the problem all together. Watch what you add in the way of electrical accessories--the bike doesn't have much extra capacity (another 40-50 watts). To pick up added electrical capacity, some here have switched all or part of their lighting to LEDs. There are threads here on how to do that.
A major hiccup with this bike is the factory automatic cam chain tensioners. As a rule, they don't last very long.
Fortunately, one remedy for this problem is permanent and relatively easy and inexpensive.
Also: since you've switched from a Wing to our bike, I think you may find that the factory seat on this bike leaves something to be desired, on long hauls. Several remedies are available, depending on your tastes and your budget.
