Well, it seems the 400ex throttle was going to be a pain to get working properly with my PWK, soooo more dollars. Quad might as well be a stripper the way I keep throwing money at it.
Picked up another polished throttle. This time the correct OEM unit from a 250R. Same guy that I bought the polished brake setup control setup from. Not sure what he used, but it is top notch polishing. Hopefully this one last a long time. They are proud of these old parts.
