okay I need a new intake boot for my air cooled 250r.. the carb is a bigger mikuni with an OD of 44mm. I was looking at pictures of the water cooled 250r' intakes and the boot looks bigger. honda says the intake gasket is the same for all the 250r's so it should bolt up. My question is is what is the ID of the later 250's intake manifold? and will it actually bolt up to the earlier air cooled motor? tanks folks
