with the help of the fantastic write-up by v7goose, everything went great and nary a leak! Did find I was able to remove the rear valve cover by sliding it back, after removing the side and middle battery covers.
Used dingy's xcel sheets, and was able to reuse a few shims because of it. Also transferred all hand data to new sheet and saved as new file, so I have a record of what shims are in now.
Buddyrich came through big-time, lending me the shim kit/tool. Put all my 272's and other odd ones in kit, but wanted to replenish the ever popular 270's.
Went to http://www.albaaction.com , and talked to Paul there. They're no longer doing a 'shim swap', but asked him about Sudco since the Yammi's were so expensive. He called back and is now set up with Sudco, so I ordered some at $6.75ea. Will add them to the kit before I send it back.
Thanks again to these members and this great site!! Between the valve adj and sync'ing the carbs, she's a new (scarry fast) ride, and good for another 50K miles.
