Honda CA95 owner new to SOHC/4 camshaft and valves
« on: March 23, 2016, 09:37:12 AM »
Hello all and especially Honda street twin folks.  I'm having a blast restoring (for daily riding) two early CA95's. I have the engine apart on one of them and came across a curiosity.  The intake valves open twice for every time the exhaust valves open once. When I examined this I saw that the intake rocker arms rest between both cams (the intake cam and the exhaust cam) and so open the intake valves about halfway.  During the exhaust stroke?  The camshaft is the one with the tach drive, so I think it unlikely that it is the wrong cam. Wrong rocker arms? Or correct as per original design?  I have the manual, done a lot of internet searching without finding any reference to this particular issue. Attached a pic of one of the rocker arms riding on both cams. Thanks for any input!

Something definitely wrong.
Either rockers out of proper location - not likely,
or
camshaft is out of proper location and/or incorrect camshaft - highly likely.

The head on the late CA95 is different for the tach equipped motors. May be a case of wrong cam or wrong rockers. I am not familar with the tach variant. Magpie owns a few CA95s and might be able to help.
