Title: Pedcock Exchange
Post by MnSpring on 09/06/14 at 16:10:09

OK, Know/Done; the Raptor exchange for the factory 'Vacuum'.
On a LS650, (needed it) and a 06, (Didn't need it, 'yet') Did it anyway.

Just picked up a Kawi Vulcan 800 (1999), and it is is carb, and has a 'Vacuum' Petcock. (Working now at 9,000 miles)
(Yea Yea, I know, my, Harley buddies say: " Gee, you finally got a bike that you don't look like a Monkey driving a Peanut".
Of course, they say that with a SMILE !

Any experience here with, that, petcock failing?
And any experience with a replacement, (old fashion kind, and blocking the vacuum port on the carb), which is a direct fit, without Mods to the tank? Like the LS650/S40.

The V800 forums, say nothing about it.

Perhaps it is the kind, which has a, 'rubber', which is NOT, affected,
by, Ethanol gas?

Don't know. Just thought I would try here.

Yup,.. vacuum petcocks all work the same way,.. and fail the same way...

Just google petcock problem...

(Suzuki Savage does show up early in the listing,.. but this is partly because we have a good solution for the problem)...

I've got a '98 Vulcan 800. At 24k, I noticed that the vac petcock was leaking. I only discovered it because I had to pull the tank to adjust the valves. It was just a very slow drip. The leak was only down the fuel line and not the vacuum line and it appeared that the float needle was doing it's job correctly.

After the discovery, I researched on a couple of Kaw forums. It is a known problem, but probably is not bad as the Savage petcock issue. It sounded like it takes longer for the Vulcan petcocks to fail. Maybe they are built a little better. It was interesting, though, that in the forums, a few people mentioned that they bought petcock rebuild kits but they failed to solve the problem. The recommendation was a new petcock, about $85. The VN800 petcock mount looks like the Savage one. I don't know if they interchange. I didn't have a Savage or Raptor petcock to compare it to.

Neither the 2005 VN800B (Classic) that I crashed in 2/2008 with 12K miles or the 1999 VN800A hotrod that I grenaded the engine at 53K miles had petcock issues.

Ran both on straight gas from the marina or regular E10 87 octane with Startron, ATF or 2 stroke oil mixed in to offset the ethanol.

Same with our trucks, the ones that see regular E10 pump gas have leaks, the ones running straight gasoline do not. The 1987 C60 has all original lines and fuel filter, the 1985 C10 needs new lines and filter every few months, the 1969 Dodge D100 gets about 4-7 months out of a fuel pump before the E10 eats the diaphragm and it needs overhauled/replaced. The 1992 K1500 Silverado gets only straight gas, runs a bit rich, but other than that has no issues with the fuel system.

E10 is evil and should be banned. Same for vacuum actuated petcocks.
