Hello
Can someone tell me what the carb mods are that rb does to a carb from a 91 kdx?
I'm from belgium so its crazy to send my carb
But i want to know what he does with the carb so that i can look for someone that could do the "same" work
Pictures are also very welcome

RB Designs website explains it all

Ok but what do they do with the slide, jetblock,...

They clearance the slide so it works with the divider plate as far as I could tell looking at mine. The jetblock work is all internal, so not sure what they do there, I would guess maybe polishing and clearancing the air passages similar to when you polish a port job in a motor. The 2 big things are boring the carb and installing the plate. Those two things alone should be able to be done by most machine shops and make the biggest difference. If I was looking for an outside source thats what I would do and not worry about the jetblcok stuff.
