Question for all of those out there that love Japanese interopperability as much as I do.  

Has anyone run across a float bowl that will fit in place of the stock one with a plug for a quick change main?  

I realize I could go to an aftermarket carb and accomplish it but I thought I would ask.

I asked Sudco but they said they couldn't really help me.  I traced the usage of the float bowl gaskets back through the early 1980's but none of the carbs the use that gasket have the plug.
