Got my TW in Dec 11, so I;m just now chasing down all these "mod" threads. For what it may be worth, our local "HobbyTown" (national franchise - one may be close to you) has #PHU8504 2.5mm Washer with a 0.125 hole that perfectly fits the needle. $1.39 for a pack of 6. Each washer is 0.020 thick.



Opinion and speculation starts here so take it for what you think it may be worth:



Reportedly, Australian TWs have needles with 5 clip positions, with the distance between each clip slot on those needles measuring 0.050. Suspect that is what we basing the often suggested 0.050.



Me, I'm running 3 x 0.020 and telling myself I've raised my needle at least one full clip position. Can't get excited about being +/- 0.010 from some purely speculative "starting value" for carb work. Proof is only what works with your bike for you based upon where you may be on the planet.

That part number didn't bring up anything. Any help on a link or somthing for some .010 shims would be great since I hear shim shim but really have no clue where or which ones to get. I did have a member direct me to some .025 but I am really hoping for a part# or link or somthing so I can tackle this with the correct parts

Take your needle to a hobby shop or well equipped hardware store and buy a couple flat washers for $0.10. Depending on your choice of main jet, riding conditions, fuel quality, etc., you'll only need one or two. If you need half or one-and-a-half, smack them with a hammer. Daily temperature variations render any finer adjustment totally anal.

It takes less than 5 minutes to open it up and take the needle out. Just do it and take it to the store with you. It is much easier than you may think.



Edit: Nevermind. I see you figured out which ones to order. Good luck with your tuning. It made a huge difference when I finally got it tuned in.
