Yep, dat be de one. Provo seems to be perpetually out of stock on all things Honda. Figures, since they're mostly Yamahish out there in Utah. Note the 17.5 to 24mm sizes on their item. (Cue Homer Simpson) Twenty four... Mmmmm.

Scooter-Center's site lets you click on the Union Jack and convert the print to English, which is sim-u-lar to American. :) I never did find a US source for the Honda/Arreche, or for the LeoVince for that matter.

huh, well i stand corrected.
thinking about what drizzle suggested, is there any real performance gain past 19 or 21 mm with the stock intake manifold if i go with the arreche?
still not counting out the crf carb, but the arreche is starting to look good.

I think the reeds and stock mani are big enough for 24, particularly if you clean it up inside and maybe run fiber reeds. A 21 carb might be enough, and sure would be easier to tune. Even the 17.5 was a big improvement over Keihin PA. They make a 19 also.

It's the cheaper of the two that look nearly the same.

There is one ending in 53 that uses a larger flange so be careful. I Just made that mistake. hopefully the email I sent will correct it.
