400F valve guides in a 350F

<< < (7/7)

Bryanj:
But Rosco only said no seals were fitted, he didnt say if they could have been BUT as a 400 they should have been unless early 350 guides have been fitted. Either way PO either fitted wrong parts or just didnt fit seals----- either way my comment stands, i was just too tired to explain at length

rosco:
Just checked my heads and both, on the inlet side the guide tops are parallel with a provision to take a seal.  Whereas the exhaust guides have a conical top with no provision for a seal.  I may be unlucky and both heads may be from an early model   Yet looking at parts catalogue it only shows seals on inlet side. Confused??

royhall:
It's not the age it's the market the bike was sold into. My 350 came from Ohio and is a very early number F0 that originally had 8 stem seals.
