Hi
This is the pic of my carb. It says on it mik carb India, and down the bottom it says licence mikuni Japan. Anyone have any idea what size it is? And point me in the right direction on ebay that would do. Thanks for your help.

Probably a 22mm or 20mm, the original on a GP 150 / 200 should be dellorto SH2/22 those are like hens teeth and cost an arm and a leg.

Jetex, also Indian, build a copy of the SH2 but they are hit and miss and its advised to at least replace the jets with genuine dellorto.

The Mikcarb is a licenced copy of a Mikuni carb fitted as standard to later model Indian Gp / Vijay.

Are you looking for a whole new one or something to replace it?

Hi All,
How do you measure what carb you have, is it the venturi you measure.
Cheers

Yes, the diameter is the Venturi, try measure it at the manifold end and see what it is.
