A new carburettor intake rubber (set) makes sure your motorcycle engine will idle and perform correctly. You often see small cracks in inlet rubbers and this causes air to pass, which causes a bad running engine. Make your motorcycle run as new with a new inlet rubber (set). *Do note that NOT each carburettor intake rubber is sold as set and the picture its ONLY for illustration purposes!
