Has anybody bought and used the xrsonly choke plate.Is it a direct fit?Because while we had the carb apart for cleaning (thanks to xl650l_Dave great help) we found that the stock one was in pretty bad shape and i was going to replace it with something stonger.Just wanted to make sure it was a direct fit.If anybody has used one let me know what you think.

I have one for my 600r, but havent installed yet. Might do it today, as my bike is semi-apart.

For my XR650R it was a direct fit.

Remove the two screws take out the old one. Be careful to not allow the choke plate shaft to slide out to one side, or else you'll have some fun trying to get the spring back in position. Use some high strength locking compound on the new screws (provided) and torque them down using the allen wrench that also comes with the XRs Only plate.

I also shortened the mounting screws they provided by a few threads. They were just a bit too long and stuck out into the airstream when the choke was off. Not a lot, but every bit helps, right? :smirk:

A mechanic friend did the install on my XR600r while we had the carb apart for a good cleaning and tune. We had to shave down the sides of the plate a little to get it to fit correctly and we definitely had trouble with the spring. After that, though, it went in pretty well. I'm happy to know that there isn't a little flappy thing that can break off and get sucked into the engine...

So that gets rid of the flap piece then? With this you do not need it?

No flapper required.
I had to run a file on my choke plate from XRs Only but only in a couple of spots for smooth operation.

The flapper is just a backfire vent and no you don't need it. Most carbs of all kinds don't have or need them either. Why Keihin thought they did is beyond me. :smirk:

I've never used the choke on my 600.

Be aware that the stock flap screws are splayed out (to prevent backing out) and will need to have the threaded end ground off to prevent stripping the tapped holes in the butterfly bar. This will make more sense when you see it. Use a dremmel to grind the splayed screws down and then you can back them out without stripping the threads. Attach the new choke plate with the new allen screws and locktite. :smirk:

I'd like to be able to peen the replacement screws like the stockers, but it seems like it'd take a special tool to do it.

A center punch with a fairly broad cone tip would work. I don't know what screws come with the plate, but brass is easier to mushroom out.

The orginal choke plate has a little metal backfire flapper on it. This little plate has been known to break off and head for the motor causing major engine damage.

Maybe he meant about the screws....:smirk:

Swaging/mushrooming/peening the threaded end after installing the choke plate keeps them from rattling loose.

I think threadlocker will do the trick.Hey Dave the plate prob won't be in until mon-tuesdayish but with all this snow i'd say there no rush.I will give you a jingle when its in and hopefully make an evening out of it.

Was thinking it might be nice to figure out a way that doesn't involve passing a centerpunch through the carb.
