CB450 K0 14C carb upgrade kits Genuine Keihin / Honda Parts ......issued 'back-in-the-day' by Honda to cure carburation problems, inc. 4k RPM flat-spot and also vacuum piston return. These are hens teeth parts ... you will be hard pushed to find elsewhere because if you note the parts they are modified by Honda and have -315 or -305 suffixes at the end of the part number. They originally came from Honda UK's Service Department. (see attached instruction sheet).

Please note these are for 1965-1966 built bikes with 14C carbs. If your carbs have been upgraded the tell tale sign is a marking of 2 Roman Numeral II after the 14C stamping on the carb body i.e. 14C II
