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.

Launch of the Apollo

On the chopping block this week is A's Yamaha XS650 engine. Big plans on this one:

-Cam and crank will be shipped to Hugh's for a rephase to 277
-Pamco ignition
-700cc overbore
-Resurfaced head and valve job
-Aftermarket oil filter
-Permanent magnetic alternator
-Swapping out transmission with a later model including 5th gear overdrive
-Hydraulic clutch
-2" sump extension
-New gaskets and oil seals

Once the engine is entirely apart, I'll be able to inspect the bearings, valve guides and any other bits that made need replacing.

Stay tuned.
