My 1st post on here... just getting my 650C roadworthy... i went thru the carbs on it and somewhere i must have goofed...It starts fine.. idles great and cruises down thwe road fine. If i crack it wideopen it will die till i back off the throttle, then it will catch and go again.... I'd appreciate any ideas on this Thanks!    Report

On a CX500 the 78 goes into the carb body and the 112 goes into the Brass emulsion Tube.Also if you have an in-line filter make sure you have not reversed the flow arrow.
