A friend came over today and helped me take the carbs off the bike. It appears it was a very good thing. I found the following issues:

  • One of the air screws was bent...And it was turned out 4 1/2 turns. The other was 2 1/4.
  • The push throttle cable was broken.
  • One screw on the coasting richening cover missing.
  • One clogged idle jet
  • Hoses on the T-fitting (reserve fuel line?) bent and cracked. Not sure whether this was existing or happened during disassembly.
This sounds (to me, at least) like it is enough to keep the bike from running. At least the jets are in really good shape, though.

Plus, folks here were correct. The rubber grommets between the tank flanges and the frame are shot. It was indeed tweaking the tank and causing it to leak between the tank and the petcock. Thanks for the advice. For the time being (and until I started working the carbs), I have loosened the bolts.

Comments?

I wasn't. I bought it in June with a leaking tank, thought I had it fixed, rode a little bit...And at that point it was running like crud. I then found the tank was leaking again (it was probably the grommets, in retrospect), and once that was fixed, it wouldn't even start.

Thanks...I hope so. The grommets are $20, the throttle cables are about $50. Unfortunately, my Kawi dealer doesn't have the parts in stock. In fact, they have never had a single Vulcan part I have ever asked about in stock (which seems fairly useless to me for a dealer).

Welcome to our world.
The hoses on the T fitting are for the carb vent. The hose leaving the T fitting is the one that goes into the housing for the right ear. This is the one that needs to be cut at an angle to stop it from bottoming out.

Thanks. I measured the inner diameter, and was going to use fuel line, but the outer diameter is too large. Can I get hose of that type at an auto parts or home store?

When I replaced all my fuel tubing, I just bought the tubing from the Kaw dealer. I took a piece of the old tubing and used the "that looks about right" method" to buy all the same size tubing. 4,000 miles later and no tubing problems. It cost me about .13/foot I think. I don'[t think the size is that critical other than the fact that it needs to seal on the fittings so as not to suck air into the delivery system. Other than that, as long as it fits, it should be OK.

I think I got mine at a hardware store. Like ya said, the ID was the same, but the OD was larger. Worked fine though.
Like Sky Rider said, as long as it fits the fittings good, you should be fine. Don't worry about the OD. :smiley_th

Thats interesting. I talked to my Kaw dealer today, and they said the long carb vent tube was $20 and the short ones were $15 each. I think not. I'll either go to Autozone or Lowe's. Since its not passing fuel, the primary concern is the inner and outer diameter.

Unfortunately, the air screws, gaskets/o-rings and throttle cables are dealer-specific.

How do you decide whether or not to replace the gaskets/o-rings? Do you do it because you are taking it apart (and don't intend to make a habit of this) or do you look for obvious wear?

Thanks,

i replace them depending on mileage. nothing worse then blowing a gasket. i would rather spend $10 and know they are good then find out 2-3k miles later that they were on their last leg.

You can order them (the gaskets and O rings) yourself from Ron Ayers or Bike Bandit a whole lot cheaper than your stealer. $20 for the vent hose????!!!!! That's a rip off!! It's not even a shaped hose. I'd stay away from those guys if I were you. It sounds to me like they are price gouging just because they can. The bike doesn't care if the hoses are genuine Kaw or hardware/automotive store specials. As long as it gets fuel and air in the right mixture, it's happy.
As far as replacing O rings and gaskets, if they are old and somewhat damaged, spend the $$ and replace them. If new and in good shape, keep 'em but be aware that you will probably have to replace them sometime down the road.

Yep. But according to them, the price came off of the fiche from Kawasaki. [Benefit of the doubt] Now maybe they were confused on the exact part [/benefit of the doubt], but how many vent hoses on T-connectors are there on the bike???

I'm not sure how old they are, and I am the third owner. they don't look that bad, but I'm a carb novice.

Finally, is there a cross-reference for the Ron Ayers site? I don't see a VN700, but I know that about 99% of the VN750 parts are interchangeable. Would things like the throttle cables fall into this category? The carbs look like they are the same model.

I would think they're the same, but I'm not positive.

Bike Bandit does have the fiche for the 700 as does the Kaw website. Just write the part number down and plug it into the "where does this part go" window at Ron Ayers. That should give you the part and price.
For the fuel and vent tubing, you should be able to buy generic fuel tubing with the proper ID as said previously. If you still want to buy the tubing from the Kaw dealer, ask for their generic tubing and price. I paid about 13 cents/foot doing it that way. I used all the same tubing for everything except the vacuum line going to the petcock.
