CB350F top end rebuild

I finally got around to finishing off the CB350F top end rebuild last week. I gave the cylinder head a quick (re)surface, I deglazed the cylinders with a coarser grit flex hone, and made sure to seal up the head gasket with Copper Spray-A-Gasket. I thought to add a little Hondabond on the troublesome jets for good measure.

The rings have seated, the jets are, um, jetting! and the engine is oil tight again! Next up, rebuilding a troublesome clutch....

XS650 rebuild continues

progress continues on the XS650 rebuild. While the crank and cam being shipped out to Hugh's Handuilt, top end progress continues on the head and cylinders....

After the new Kibblewhite valve guides are installed, the I.D. must be taken down to size. Gene showing me the ropes as we hone down the Kibblewhite valve guides to perfect clearances.

After the guides were dialed in, the seats were cut and the head resurfaced.

Here, the cylinders are being rebored up to 750cc.
