Indian made Mikuni carb clone often used on Lambrettas with unusual slide lifter mechanism which might be very useful on a custom build with limited carburettor top headroom  

Brand is MIK CARB and internal diameter of venturi is around 20/21mm ish , The ID of the fitting insulator band is 27mm and the OD of rear to take airbox boot or pod filter is 43mm   

Is in good condition with everything working including choke components , I have turned the pilot jet , air screw and idle screw so nothing seized , comes with a clamp but this is a bit bent so will need straightening before use 

Any questions welcome
