Phil,
Thanks for the comments, it still has a ways to go but thats how shes doing as of now until funds prevale.. When I refinished the engine I first bead blasted the cylinder block, head, and rocker cover while it was all together. I obviously closed off the exhaust and intake very tightly when I did this to make sure none of the sand went in. I also made a big cardboard cut out that I put over the top of the bottom end at the base of the cylinder block to act as a shrowd so the majority of the beads woudldnt even touch the bottom end. I used one of those portable blaster guns that you hookup to an air compressor. It worked great to get all the corrosion off the fins on the top end. Then I knocked off any loose paint on the bottom end, hit it with a little sand paper here and there where it would be noticable that it had chipped off.. Then I removed all the engine covers and taped off under them, for the clutch I actually just set a towel around it and made sure it was tight enough in there that it would keep the paint out. After that I taped off the top end that I bead blasted, hung it from a chain fall, and sprayed it with some high temp silver. After that I took off the tape from the top end, and cleared the whole thing with high temp clear. I wanted to make sure the fins on the cylinder block didnt corrode again... As you can see from the pictures I used the wrong clear, instead of 1500 degree it was 500... So it turned brown when I got it running... But thats ok, Im going to be pulling it out over winter and replacing the top end seals anyway... so I'll blast them again and I've been thinking about doing it black with the PJ1.
The yamaha is actually the CB650, I was trying to find a tank that would fit the bike that had knee inserts that would look decent. But I think over winter Im going to talk to mototumbi and see if I can get them to do a dunstall tank that would fit the 650. I have an old junk tank that I can cut the bottom off and send to them to see if they can match it up.. we'll see. Those dunstalls you found were a great find Im sure they're going to look awsome on that bike when its finished. Keep it up, nice to see a guy working on a 650 instead of a 750. I thought I was the only one haha.
