Morning. I have a mate who's just bought an Indian GP 150. Everything is/looks standard. What would be best carb & exhaust to get a bit more out of it without changing barrel & piston at the moment. Thanks in advance.

Standard 22mm carb and maybe either an Indian 'Big Bore' pipe,or a 42mm 'Clubman',go up a couple on the main jet,and there will be a noticeable difference!

Genuine Dellorto 22mm carb will be hard to come by. Indian 22mm Jetex quality is very hit and miss, probably less than 50% function correctly. Scootopia have had the Dellorto 22 remade in UK and currently under testing. I'd wait for those to come onto the market. The Scootopia Clubman is a lovely bit of kit too as it has a separate stub fitting making removal much easier.
