1965 Superhawk restoration - restarted

I have restarted the restoration of a Superhawk from last March '11. This is a link to a thread I started in the general section which contains info on the motor ser # and frame #, a brief summary, and some photos I posted of the bike and the major damage that caused the breakdown. The bike still started and ran but would not go, transmission destruction!!!

I have a Clymer service manual, Honda 250, 300 Shop Manual, and got both Bill Silver's books, so I have good references. And, of course, this forum, great resource, thanks to all for all the comments, tips/tricks, etc.

Since then, I have taken the engine/tranny completely apart, cleaned the cylinder, cylinder head, split case and many of the internal parts. Here is a short list of what I have done in the last two weekends. Again, the engine in the bike has been restored once before in the lat 70's.

- Pistons, cleaned and measured at 59.65/59.67
- Cylinders, cleaned and measured at 60.0
- Started breakdown of Cylinder Head (as I go through this I will surely be asking a few questions), but I am looking up as much as I can on the forum.
- Oil Pump, started to inspect, clean, and tear down.
- Crankshaft/Connecting Rods, cleaned, inspected,and performed the forum and Clymer service manual deflection check. Will check all the bearings and other areas with a dial gauge.

I cleaned mostly with simple green, which worked wonders on just about everything to include all of the nooks and crannies but I had to use a lot of elbow grease. I used brass brushes, steel brushes, old toothbrushes, and other to clean between the fins and all the surfaces of all.

Piston cylinder Hone

The cylinders seem to be in good shape and spec out as good within tolerences. What is the best way to hone these cylinders?

I have checked all the parts stores and all they have are 4" honing stones for auto. I have not yet checked the cycle shops around.

Any suggestions? Comments?

I believe I puchased a suitable size hone at Kragen / Oreilly auto parts store. Otherwise, search Ebay or Amazon.com for either a stone or ball hone to fit.

Cylinder Head Teardown

OK, I have began the teardown of the cylinder head and have removed both cylinder head side covers, Inlet/Exhaust rocker arm pins, and the right side cam shaft. I cannot, however, remove the left cam shaft. It will not release from the Cam Sprocket. Any suggestions? (See photos)

Next, are the rocker arms. Is this ok wear on all four of them?

The Tappet adjusting screws, are these ok? Bill Silver manual says look for "flattening"

I also had a lot of troubles removing this part.

I had some hard wood between the camshaft and the egine frame. Otherwise the bearings came out when I hit the axle. Then put a nut on the axle and hit it wit a hammer. Hope this helps.

I can take a picture if you want when I'm home. It can be very stuck ;)
