Back to work on this. First off, I needed to have a little snack... Got the wiring harness in, made all the connections, installed the headlight bucket, gauges, and front signals. Flushed and bled the front brakes. Then I spun the rear wheel, and saw the cush drive wobbling. Put the dial gauge on it to see how much it was really off. I surmise the previous owner had a chain mishap/ broken sprocket, as the entire outside of the cush has sanding marks on it. Anyway, the sprocket face was messed up and I had to put it on the lathe to get it clean and smooth again.

Ready to start stripping paint. Everything is done save getting my head back from the shop. Used some 50 thou thick aluminum sheet to form a mudguard. Mounted a taillight and plate holder. Drilled holes for the side badges.

Long story short, the shop I had tasked with refurbishing my cyl head hadn't gotten around to it, so I took it back to at least clean it and figure out what really needed to be done. After some time in the ultrasonic tank, it cleaned up nice.... But then I looked closer and found cracks 3 threads deep from the spark plug hole to both the intake and exhaust valve seats on the middle 2 combustion chambers. grrr. It's a shame really as the rest of the head is in pretty good shape. Apparently pretty common if the engine overheats or isn't given enough time to warm up properly. There's conflicting information on the 'net whether it's ok to use as is. Some are concerned about the pressed in seats coming out. Others say it could have been like that for years. I'd be interested to hear other folks opinions here. So in the meantime I figured I'd put my effort into a different casting. I dug out a spare gungy head with rusted and seized exhaust valves to clean up and check out. It's been in the tank all day and doesn't appear to have any cracks in it. Here's the 'before' picture.... I love old bikes!

Good to see your getting it done. May be a good thing that the engine guy didn't get to it. The second head looks good cleaned up. That thing seem to do a good job eating carbon.

Man, these things have a way of breaking your heart along with your bank account. I found that out the hard way with the GPz/kz 550 trackbike.

The stock rubber rear footpegs looked a bit weird with the tarozzis, so I threw a chunk of 1" aluminum bar on the lathe and mill.....

What happens when stock valve springs and guides are used with a high lift cam. Chewed seals, broken springs, and mangled guides. My new guides are 2mm shorter and can handle up to a 0.500 lift cam.
