Well, hello!

I recently purchased a '92 Vulcan. The previous owner hasn't used it in three years. I purchased it as a project bike, so I could learn how to work on and upkeep my bike while I learn how to ride through the STAR training course. The problem I'm having so far is the seat. I understand it covers the battery. The front part will come off, but it has a lock on the left side. The ignition key fits, but wont turn. I've tried wd-40 in the lock, still wont turn. I've tried rocking from the top, but that doesn't seem to work either. What should I try next? How can I make the key turn?

Thanks

Lock on the left side? You mean the helmet lock? You need to open the small compartment behind the seat that is above the taillight. There are two 10mm bolts holding the seat on back there. . . .

Welcome aboard!

So, the set of bolts on the back keep the rest in place, but don't seem to have anything to do with keeping the main seat in place. There are two locks on the side of the bike. I feel like it has something to do with one of them.

That's definitely not a stock vn750... Are you sure it's a 750?

There's usually only one lock (for a helmet) on the side of the grab bar where that chrome lock is in your picture, but it's usually a different style. That one tucked in underneath on the fender is a complete anomaly. The vn750 also comes with just one seat, held in place only by two bolts inside the locked compartment behind the seat. If there are two seats on yours, someone has done some fancy modifications, and you may need different key than your ignition key to get it off.

Can you post two more pictures? One wide shot of the bike, and one really close one of that lock and the cut fender that it's sticking out of?

Looks like it may be an 800.

Edit: Try sitting on the seat with your full weight and try the key. Shake the key up/down while turning.

Aha, the 500. Yeah, try putting downward pressure on the seat to relieve pressure on the latch when turning the key clockwise in the more inset lock. The chromed lock is the helmet lock.

Yep that is a first generation Vulcan 500, which evolved from the 454LTD. That is a great bike. I actually wish they had made the Vulcan 750 that way. 750cc parallel twin with shaft drive. It could have avoided all the issues with the Vulcan 750. Although I love riding the Vulcan 750, IMO it is an engineering nightmare, with twice as many parts as it needs, and cobbled together out of parts that don't quite fit. It is definitely an oddball bike though. And that may be the reason why people who have had them for a while like them so much, and are willing to put up with all it's problems. Some people have been through several stators. With any other bike, it would have likely wound up in the landfill after the first one.

I am a motorcyclist, NOT a biker.
