You and Geoff were right, LM. Thanks to you both for solving the little mystery.

Cleaning parts today, but primarily carburetors. I scored a pair of badly corroded Keihin PW26s for the parts i needed. I found that the PW26s that came with the bike (but not mounted on the engine) have CL77 stamped on their flanges, but no matter, they'll get the correct jets.

I had to scrape the dried grease and dirt from them, then washed them in kerosene, then a night in a gallon can of carb cleaner, a day in a gallon can of lacquer thinner and now in an ultrasonic bath. They'll get a rinse and i'll blow them out with compressed air and check that the passages are clear. When the parts kits arrive, they'll be reassembled and set aside for later.

They'll look superb after all that treatment!

Thanks, G. I don't know if they're superb, but they'll do.

I think these are the carbs wit the nylon slide centering guide.
You have done a lot of cleaning with chemicals so may want to see if they are still there. ......................lm

Learn something new every day. Thanks, LM. One is nylon and the other is metal. Both are there. What's the reddish brown stuff Keihin painted on hold the metal guide in?

Beats me.
I think it's more of a sealant than a glue. ..................lm
