What's the difference? (Fuel selectors)

[Ryan727]

So I've got a '99 & '98 GTX 951. BOTH of these fuel selectors leak out of the RES (reserve). This leak occurs when I take the selector off, switch the fuel to ON, plug the OUT hole with my thumb, then blow into the inlet.

So both were doing the same thing, I thought maybe there was some leeway there, and it wouldn't matter much. So I put one of them back on with my new fuel lines. I pull the carb's return line from the MAG, blow into it to see if I can get things moving around. The tank and lines hold pressure, but once it gets to a certain level, I can hear the selector whistling (can't tell you at what PSI, does it even matter?). I can also hear bubbling in my fuel/water filter. I assume there's too much air getting in there?

Anyways, I figured I'd replace the darn thing for $20. May as well. Everywhere I'm looking is selling what-looks-to-be exactly like mine, but then it says in big bold letter, "EXCEPT 951 MODELS".

So.. WHAT'S THE DIFFERENCE? Here's a pic, looking on SBT's site before I drive over there to get it:

951s use 5/8 hose yes 951 selector is more $ needs to be done carbs sucking air = lean = motor poof !

So, just larger ports to compensate more flow of a bigger engine?

Yes they use more fuel ALSO MANY DIFFERENCES between98 &99 ignition & pumps

 

[Ryan727]

Ignition, yes. Fuel delivery systems are identical (Hoses, valves, filters, carbs, & baffles). I was able to swap parts between the two. Doesn't matter either way, both are aged too much.

98 has red handlebar cover 99 is black

 

[Ryan727]

I've got 2 '99 bodies, just one has '98 guts. I wasn't responsible for the swap, though.

The picture you posted is wrong and too small for the 951. 951 uses 5/16" fuel hoses not 1/4".
The stuff from SBT is crap and should be avoided.

Either get and OEM valve or I have had good luck with the WSM ones from PWC Muscle @hfgreg #006-604 .

 

[Ryan727]

Well I just drove over to SBT and picked one up before you wrote that.. Looks to be of decent quality, no plastics on it. Ought to be better than what I got for now, and for a cheap price.

Ok, good luck and you have been warned. I would make darn sure it isn't sucking air and leaking as the SBT ones have been known to be bad out of the box.

 

[Ryan727]

No leaks out of the box, but will take into consideration the need to look for a better brand soon.
