Mikuni VM26 / VM28 Yamaha set
Motocarb supply this set to fit the early Yamaha road twins from the YDS7 / YR5 to the RD250 / RD350
The set is available in 26mm and 28mm versions.
It features factory stock jetting or your choice fitted on request.
The carbs are supplied with left and right idle screws and the factory OEM type linked choke with the correct size starter jet.
Ready to fit.
There is no availability of right side throttle slides at the moment
so this conversion is not available until I can source them again.
I can still supply them as 2 x left idle carbs for race bikes.
This carburettor set is also suitable for the GT250 Suzuki and other similar 2 stroke twins with a 35mm spigot type fitting.
