I'm new to atvs and I just bought a 400ex with a 440 big bore kit, stage 3 hot cams, full yoshimaura exhaust, and a oversized oil tank. The only thing it needs is the carb rebuilt but how would I know what size the carb would be? I wasn't told if the carb was changed due to the big bore kit. Would it tell me on the carb? Also is there any other specs I should do to it? I want it done the way it should be.

 

Also after I rebuild the carb would I have to get it rejetted again?
