Yo

Hello out there. Trying not to be a lurker. I bought the Vulcan for $100. It hasn't run for a year. The guy who owned it didn't know how to fix it. Charged up the battery. It turns over and there is Spark. Smells like it is getting fuel. So I will be taking it to a repair shop. Fairly certain it has something to do with the timing and that's not my area of expertise. I'd rather pay somebody to fix it right. But at any rate, thank you all for your posts for us noobs to learn from. I have been a Harley owner in the past but but can't stand the markup and the need for constant repairs and I really like the looks of this bike. The only mod I will make is add the vn 900 seat. Looking forward to when I can ride it. Regarding the 900-seat, I have seen on eBay that they sell quick releases. In the threads that I have read on modding this to fit the 750, looks like everyone does the bolt down. Is there a thread out there where they have modified the quick release for the 750? Thanks again for all of your posts.

Welcome. I doubt it's a timing issue, most likely clogged jets from sitting so long.

you could spray some starter into the carbs (may need a friend) and if it sounds like it would start then it's the carbs needs cleanin.

Thank you both. It started with the starter fluid. So Off with the carbs. But the rebuild kits are really expensive, compared to what I paid for the bike. Is there a vn750.com sponsor that has them for a good price?

On a hopefully unrelated note, there's is a slow fuel drip from behind the motor that I can't locate. Is there a fuel line back there?

Probably dripping and running to the back, but no lines in the rear.

Run your hand across the bottom of the carbs, might be one of the bowl drains dripping, a float stuck, bad fuel line, etc.

I wouldn't even use a rebuild kit, just order the parts tht are bad off a site like partzilla. I would reckon a new set of jets unless you can get them really clean, and the o-rings for the float bowls and the jet cover, as those pieces of rubber are usually trashed and hardened. Other than that, check to make sure the diaphragms move up and down with some slight resistance and a whoosh sound, check the o-rings in the accelerator pumps, but those were OK on mine.

Basically, you should only really need to replace any bad rubber parts on the carbs, deep clean them in a chem dip or ultrasonic cleaner, and get the jets either cleaned or replaced.

Found the drip... It was running to the back. The was a split hose on the right side, no idea what it was for. It goes over the rear cylinder head toward the rear. I cut the split out and reattached it. Bike runs SWEET!!! This is turning into the best $100 I've ever spent. The PO had no clue. Now only one more issue. The petcock is leaking...
