my mates been busy making progress with the kart
cut the bike exhaust flanges off the manifold and fitted them to engine in preparation for making the manifold (excuse him being a fookin plum and struggling with counting to 4

)
mounted the race can
also fitted the air filters and carbs
fuel pump, fuel supply isolator and gear selector
i think the isolation valve in the fuel line needs to go before the fuel pump straight after the tank, will have to make him change it
