Can someone give me the factory valve/seat angles for the cb500 exhaust and intake?  45 degrees? Thanks!

Awesome! I've looked through my handbook and performed a few searches with no luck. Thanks.

Wont be in handbook only in manual. Honda seats are supposed to be ground not cut by the way and they dont recomend doing the valves themselves

The valve faces are Stellite coated, very thin hard surface. They should not be reground, only lapped in to the seats.
