A friend and I that both just recently purchased XR650L’s installed the standard mods this past weekend; snorkel removed, K&N filter, #55 Pilot, #165 main, shimmed needle, and new Big Gun Exhaust complete system. The result was fantastic with excellent throttle response throughout the range.

I have a question about a difference we found between the two carburetors. One had the white plastic piece that fits over the main jet (shown in figure 10 of the 4-strokes.com instruction for this mod). The other carburetor did not have that piece at all. Both bikes run equally well. What is that plastic piece for, and is it needed? Of course there is concern that that piece may be required for some reason.

I believe the white plastic piece is a baffle to control fuel sloshing around in the float bowl. Are you sure it didn't fall out of the second bike?

No It was definately missing. I ordered a new one from the Honda Shop. Of course they wouldn't cover it under warrenty unlesse I ran it through service. Nahh, rather do it myself.

Thanks for the information!

Hit up your dealer. There only a couple of bucks a piece. Any dirt bike shop will have them too.

Same here. The stock one was shorter. It was below the level of the pilot housing in the carb. The new one came up flush with the housing as shown in the picture on 4strokes.com. I figured it was OK since it matched the picture. Mine runs fine but I am also interested to know if there is a potential problem.

XRL_Dave ??? How long is long???

My long one was out to, or sticking a little out of, the pilot jet well. The stocker was well recessed in the well.
The long one seems to work OK, but be aware the slosh baffle can wiggle around and cover the jet. I trimmed my slosh baffle a little to make sure there wasn't an issue.
Took me a few days to find what was causing that little problem!

Hey Dave, what were your symptoms of it??? I recently have the problem that when I come from higher speeds and rpms to a quick stop that my idle goes way down and the engine dies. It doesn't do that very often and if it happens it starts right back up.

I was thinking to start looking/cleaning my carb and plug...

My prob. was only large throttle settings worked, stalled elsewhere.
But if it only covers it a little it'll change the jetting, so if you have the long jet, you need to trim or relieve the baffle to be sure that's not the problem.
