happenings around the shop

the XS650 build is continuing on it's slow and stead pace. problems with the stock head gasket has prompted a custom made copper head gasket. with the gasket on it's way, the build will nears completion.

m.'s CB750 had a few charging issues that were sorted out, but he was still going through batteries fast. the original builder of the bike had the wiring set up with the headlight, tail light, speedo and tach lights all on once you turn the key position to on. m.'s 3 amp/hour battery didn't stand a chance handling such a huge draw. I installed a waterproof accessory switch, so that with the key switched to the on position, the only draw are the coils and the pamco ignition (0.020 amps). With the accessory switch, all the lights can be saved for after dark.

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

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.
