I've got set of black chrome headers (loose)pipes I was going to make a collector to suit my gs550 cafe' you can have em for postage if you need em have collars too. Not rotten or owt just need a collector making. Also loads heads blocks bottom ends too.
You don't need it unless it's remote tank or such, the fuel gravity feed would suffice am pretty sure! Carbs would only need 2psi anyways ! Had it got regulator too?
