650R Carb question

Hey guys (snaggle),
I picked up a gently used bone stock '00 the other day and after not having run for over 6 months it fired on the first kick. Yay.
Tonight I'm doing the uncorking but have been halted by the wrong jets.
No matter there and an easy fix in the am but my question is: How do I remove the needle to relocate the clip?
Is it done by removing the linkage and sliding the slide out the top?
I've checked a few sites (BRP et al) to find a tutorial but have come up dry.
My carb experience is exclusive to my lawn mower and about a dozen FZ1 Ivan's jet kits. So, I'm not a total spaz but I have my moments and don't want to go too far down an unfamiliar road only to find I need a special tool or more brain power. At least I could buy the former.

Also, my local shop was stumped by the part number for the carb to head manifold replacement part. (p/n 16211-MBN-640)
I've seen varying methods of uncorking....
One mentions the manifold but no air box mod (removal of a piece of plastic).
Another mentions the air box but not the manifold replacement.

Which method have folks found here to be the most effective?

Thanks for any thoughts!

If your Honda shop is on the ball , they will understand "power up kit" which includes (Exhaust tip, needle and needle jet, main jet and manifold)

Go to your Honda shop, p/u the "power up kit" for your "00-06 XR 650R"

Let us know when you have these parts. The rest is sooo easy.

Thanks, but I'm just going to drill out the tip.

Thanks guys. That saves some shekkles and driving around.

Now, if I can get the needle out without buggering anything up I'll be home free.

We will be standing by. There is that pesky little spring..... you will be fine. :thumbsup:

Thanks MP.
So, it is just a matter of the linkage and the 'Jesus' spring.
Sounds like a fun little morning project.
I'll let you know how it goes. Hopefully I won't be crying about doing something stupid.

I remove the set screw that connects the linkage to the big return spring--that makes things easier for me. I also replace the two little philips head screws that connect the linkage to the bottom of the slide with little allan head screws. Those little philips jobbies are too easy to bugger up. Actually, I replaced all the philips head screws in/on the carb with allens--much better (just don't over tighten!).

While you're in there fix the choke flap by either removing the hinged part or buy the PC choke plate.
