Need to fix oil leaks

My 92' VN750 leaks a lot of oil from a few places in the motor.
I'd like to put new gaskets throughout. I'm no mechanic and
I'm on too tight of a budget to take it to a shop. I was wondering
how involved it would be to take this on myself?
Any tips would be greatly appreciated.
Thanks

A lot depends on just where the leaks are located. A valve cover gasket replacement is much easier than a head gasket.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

mine was leaking from I believe the stator cover a little maybe but definately the tranmission sight glass cover, stator cover needs engine removal and I highly recommend removing it for the tranny cover.
If yours is leaking in the front of the engine from what appears to be the base of the top cylinder it could just be the orings in the spark plug wells which is a 5 minute job and just a couple bucks!

Thanks for the info. It's leaking from the front and back of the motor.
It's leaking from the top gaskets (valve covers?) for sure and maybe more?
I'll check out the o rings in the spark plug sockets. I hope it's something
simple.
Thanks again

The nut off the rear axle fits inside the spark plug socket when the plugs are out, then a wrench on the nut to remove the socket!

If it is leaking from several places, it is probably not going to be simple. One of the Vulcan 750s flaws is it is very difficult or impossible to do any work on the motor without removing it. Mine has only had one oil leak, around the grommet where the stator wires come through the cover. It was a minor leak, and I just stuffed a piece of paper towel in a cranny in the engine below the leak to soak up the oil, and ran it that way for several thousand miles. I finally got some contact cleaner, cleaned all the oily stuff from around that grommet, then put some Permatex oil resistant RTV sealant on it. It hasn't leaked since.

I am a motorcyclist, NOT a biker.

Thanks for the info. Sounds like a good idea. Also, I noticed on your list of mods that you relocated your horns. Could you tell me where and how you relocated them. That's something I've been wanting to do.
Thanks again

I relocated then one on each side of the bike, under the ears, right about the middle of the black part of the ears. I used some left over brackets that I got from work. They were putting new radios/electronics in some new cop cars, and that stuff comes with all kinds of brackets for different situations. I usually grab what they don't use, and happened to find exactly what I needed. I removed both the horns, horn brackets, and Kawasaki emblem from the forks, and used some more of those brackets (different type than for the horns) to build a mount for a leather tool bag, which covers up where all that other stuff was.


I am in the process of converting my '02 greenish black Vulcan to '97 colors, red and bronze. soon as I get it together I will post some pictures.


EDIT: I just remembered these old pictures from a few years ago. They were taken in the shade with a cell phone camera, and don't show much detail, but you can kind of see where the horns are at below the ears.
