aermacchi

with everything clean and tidy, new gaskets and a few more centre-punch marks on the rubber gasket mating faces, [it stop's the rubber's spinning out of position and cut's down on oil leak's], it was time to contact-sdhesive the rubber's in place and re-assemble the head, pushrod's back in position, spin the motor over to make sure the valve timing is correct and nail the head back onto the cylinder, [being careful to align the aluminium oil return tube] the head is unusual in that there is no head gasket to speak of, i don't know if this is common on the road bikes or if it's just a way of gaining a little more compression?, the motor slipped back into the frame and we used flanged stainless nuts to fasten it in, last job was to remove the studs from the inspection covers and turn up some stainless allen screws to replace them, i just think they look better than a stud and a normal nut.......
