The one I linked to appears to be more of a keihin clone. No?
Just trying to be clear. The SWR carbs are made in Taiwan and are oem for some Yamaha and Suzuki models. Tool-wise, engineering-wise, quality-wise, Taiwan generally ranks with the Japanese. Unfortunately for them, sometimes, since it makes the Chinese that much more loathe to let them free to run their own affairs.
I really wish the Mikuni vm18 and vm20 had spigot mounts. It's a small thing, but still...
Isn't this more like a (no longer available spigot model) VM20?
