  1. Carbs & Fuel System
    So in my quest to get this 89 vn750 on the road, I had to purchase a petcock. I bought one that was "OEM" from eBay for $50. Not sure I'd the brand but it came in a black box with a red stripe. Anyway, I immediately leaked. They replaced for free. The second one leaked 3 months then leaked...
  2. Carbs & Fuel System
    Hello all. So I am working on a 1988 vn750. The bike is in good shape but the fuel level sending unit is missing. And apparently finding a used one is impossible around here or on ebay. With that said, I know someone mentioned that they just deleted it by using an O ring pressed down by a...
  3. Carbs & Fuel System
    Hoping for some help, at least a little insight. My father recently purchased a 2005 750. It had been sitting in storage for about ten years. The tank was full of rust and petcock plugged, that was remedied. After reinstallation of the gas tank, a leak was discovered on the carb. It appeared...

    Anyone have advice on where to find a replacement gas cap for a '92 750? And also the step by step on replacement? Mine is leaking. Thanks!
  5. Carbs & Fuel System
    My petcock is leaking on my used bike. It seems like it is leaking from every place it possibly could be but I'm going to try to replace the O ring at the top to see if it fixes it anyhow. In the event that I do need to buy a new one is there one anyone recommends? The strange thing is that mine...
  6. Carbs & Fuel System
    I have these strange ports on my gas tank that I have never seen before. One has a hose attached that leads to nothing just under the bike and the other is open like the picture shows. If I go out and look at the connected hose I can see fumes from gasoline and I can smell it as well. I dont...
  7. Carbs & Fuel System
    TL/DR Version: I replaced my '90 CA emissions tank (with the two nipples at the back) with an '89 tank that's only got the one nipple pointing to the left. Which of the two tubes coming through the frame just below the front of the seat do I hook to that nipple, and what do I do with the other...
  8. Carbs & Fuel System
    I bought a 2003 Vulcan 750. The bike had set for an unknown amount of time with gas in it. (the guy said 24 months.. but the tags expired in 2009) I got the bike home shot some brake cleaner up in the carbs and it started right up. I took and emptied the gas tank. put half a bottle of Seafoam...
  9. Carbs & Fuel System
    I have a '94 vulcan with about 25K miles. The bike has been running great with a couple of exceptions, which I'll explain shortly. The other day I was out for a ride for about an hour and I was cruising down the highway when suddenly, the engine started bogging down, losing power but not...
  10. Carbs & Fuel System
    I've had a project bike that I've been working on for close to a year now; '93 with 8,500 miles. Needless to say that judging by that description alone, one can assume that at some point it has sat for awhile with little usage. History so far: I've thrown lots of parts at it getting it to...
  11. Carbs & Fuel System
    Hi, Just putting my vulcan 750 together & getting it running, it seems now that the carbs are constantly flooding resulting in fuel spilling down the engine, also it looks like the carbs are flooding the cylinders because there was an almighty bang from the head, I thought a piston had hit...
  12. Carbs & Fuel System
    Just a friendly tale for those who are lost diagnosing problems. Learn from me! So I had a problem with my front cylinder not firing. It wasn't spark or air so I took apart the carbs. They were sparkling clean sans 2 tiny bugs that got into the front float chamber and carb bowl. With carbs...
  13. Carbs & Fuel System
    I just bought a 1984 ZN700 about a month ago. I have rode it to and from work about a dozen times with no problems. I took it for my first longer ride this weekend, and started leaking gas! I rode about 200 miles, and then the bike sat for about 2 days, when I took it out the next time i...
  14. VN750 General Discussion
    Hello all, I did a search of the forum, but couldn't find anything about miles per gallon, so I thought I would post a question : what is the average mpg you all get? I ask because I was figuring I would get between 40-45mpg, and it seems like I am only getting 35. Does that seem low, or is it...
  15. Carbs & Fuel System
    I was able to remove the carbureator this afternoon in order to attempt to clean/rebuild them. This is my first bike and I have NO experience whatsoever. Can someone get me a link or instructions on what I need to do? I saw that a carb rebuild can run $300, but would it run that high if I have...
