I had one also, never heard of hydraulic lifters in a Honda M/C engine, they are either bucket under shim or the rocker w/adjuster screw. if it is a 250, 450 or 650, it will have adjustable rockers.

Nope. Honda had some Nighthawks (specifically the 550 and 650, per my memory) which had DOHC with pivoted followers, the pivot point of which was located on a hydraulic "lifter." That way, there was automatic clearance adjustment, but the lifter mass is not in the reciprocating mass of the valve train. I don't think the Nighthawk 750 or "S" (tarrif-beating 700cc) ever got the hyd. lifters, but I'm not sure. I think the Nighthawk 550/650 were in the mid-80's era. I always liked the Nighthawk 650... classic looks, shaft drive, air cooled but with external oil cooler... nice bike.

CB700SC Shaft drive, hydraulic lifters, brakes & clutch. Good low maintenance bike. Used to razz the harley riders in the factory I worked that while they were tearing the moter out of their bikes or otherwise working on them that I was out riding
