Stic Metering Block suppliers and info

[cr750]

Hello all!

I am looking into upgrading my 38mm PWK Air Striker with a Stic metering block.

Are there any US or North America suppliers for these?

I was browsing Google and ran across the Tokyo Offroad site/store. While looking at the pictures I noticed "Made in the USA" milled clearly into it. That sort of made me think "Why buy a USA made part, that was shipped to Japan, only to have it shipped back to the US?



Also, it seems a good starting point is somewhere around 48 to 52 on the pilot jet and 190 to 200 main jet. Is this still an appropriate range to start at?

Thanks!
