Fuel Petcock and Float Needle Questions

I've an '09 KLR that I'm the original owner of.

I've always been a proponent of: "If it ain't broke, don't fix it." Of course I don't ignore preventive maintenance!

The vacuum petcock has never given me any issues and I like it and don't plan on going manual. But I'm wondering at this point if I should consider a rebuild of the petcock as a preventive maintenance item?

The original float needle is still in the carburetor too. Should replacement at this point also be considered? I've got a new one in my parts bin, still in the Kawasaki packaging. Does this unused needle have a shelf life? I'm not sure how long ago I purchased it.

Well, certainly there have been enough postsover the past 20 years to suggest the vacuum petcock can be problematic......others have had good luck with them for many years/miles.....I'd suggest the difference depends on ethanol use and regular usage (both riding and turning the handle on and off). Personally, if you want to keep the vacuum petcock and it's working fine, I doubt I'd bother, same with the float needle and no, it doesn't have a shelf life. If I was running the vacuum petcock (which I'm not), I'd add one of the later Gen2 fuel line filters to help prevent petcock rubber bits from getting into the carb.

My 1987 85,000 mile bike has had 1 each (Fuel Valve) diaphragm assembly, selector packing & handle o-ring changed in 34 years. (That was possibly 10 years ago)

I'd suggest that part of your success has to do with regular riding/use and the fact you're smart enough to turn the handle every now and again to prevent the selector from sticking to the rubber. There is also the possibility that the supplier of the diaphragm has changed over the years and some are worse than others.......not sure

Yes, I almost always ride down into the reserve fuel supply, so the selector handle is kept active.

Even the manual off fuel petcocks can put rubber bits from the selector gasket down the fuel line when people leave them ON for too many months with-out being turned to reserve or Off like they should be.

I like the idea of adding the factory inline filter to my '09.

However, in looking at the parts diagrams, I have some questions that I'm hoping one of you have actual experience with.

The parts diagram shows the '09 carburetor part number as 15004. This year also lists the inlet L-fitting with 2 o-rings as 92005B.

Moving to the '10 parts diagram, the carburetor part number is also 15004. But the inlet L-fitting is not listed and appears as part of the carburetor body. The mentioned inline filter is shown here as 49019 (not shown on '09 diagram).

Main question is will the filter fit the '09 inlet.

As additional confusion, Eagle Mike lists the inlet elbow with the following description:

Replacement fuel inlet elbow for carb with o-rings. This is genuine Kawasaki part. This fits carb's 1987-2009. In 2010 Kawaski changed the carb.

So has anyone actually put the filter in the '09 elbow? I hate to buy parts and tear into something only to find fitment issues.

R/L,
The PREFIXES of part numbers you are using just help you navigate to the full parts LIST. The actual part number would be 49019 -(????).

The tiny little filter intended to fit in the Throat of the Permanent fuel Elbow of 2010+ carbs will fit inside the FUEL hose of the 2009 and older carbs. (The 'duck-bill' should face up-stream anyways.)
But a common ordinary, clear or translucent, $3-$5 sintered brass or screen type in-line filter will allow one to see any crumbs in it!

It is recommended to NOT Use paper type fuel filters with ethanol fuel & gravity feed.

Thanks everyone.

I'll follow-up with my local dealer (I trust them and they are good to me). If they have some local experience that indicates I should rebuild the petcock, then I will.

At this point I'm sitting tight. This setup has served well for 10 years (knock on wood!!).
