We have been producing diaphragms since 1988, and take pride in not being constrained by genuine part supply.
We are the only source of many discontinued parts for older models, at much more reasonable prices.
We cover Mikuni, Keihin, Hitachi, Tokei and TK Kikaki carbs from 1970's to 00. Where as an original part the diaphragm is only available as a complete sealed unit, we offer a service where we refit a new diaphragm to your original slide. Where the original part can be improved to ensure long and trouble free service, this is incorporated into the design.
