hi all need a heads up regarding vac pipes in an around my bay its a 1600 twin port with standard dizzy ,airbox etc im o n the last stages of resto n dont know what pipes go where n what pipes i have missing. heres some pics of mine if anyone with same setup could take some pics of theres that would be top dollar.
looking at the bottom piccie, there one of the fuel tank vents missing a pipe - you have the t piece in the roof of the engine bay, Im certain the loose pipe from your airbox should push onto it! Our 1641 is slightly different as we've got a pancake airfilter
