^^ All that ^^. And...

Check the timing with a strobe lamp on the F mark at high rpm, and install new spark plugs of the correct heat range.

At the end of any 200 mile ride on a 90F degree day my bike would sputter so badly getting off the line that I hated stopping for traffic lights. I was convinced it was thermal effects on the EI. Turned out it was something funky with the old spark plugs.

Hope this helps.

:cheer: sorry that It took me so long to let you know that my bike is Fixed. Been out riding a lot. I am lucky to have meet Howard Hetkind, I think that is his last name, anyway Howard has been schooling me in the "Airhead" ways. He has graciously helped me fix my bike. It was the rubber grommet between the carbs and cylinder head. it was cracked causing a vaccum leak. Thanks for all the help.

No problem and glad to hear it had a great outcome !

And thanks for the heads-up. Classic, vintage and veteran motorcycles all suffer the same list of recurring ills. #1 is, of course, fuel problems related to storage with ethanol fuel in the carbs. #2 is rubber rot. Hoses, o-rings, and seals start to get hard and begin cracking open with age, starting at about year 35.

All riders should plan to include replacements for intake hoses, fuel lines, carb diaphragms, petcock packings, fuel tank mounts, and other "rubber" items over the next several parts orders. These are the least expensive parts which cause the biggest rider headaches.

Note that some of the specially shaped engine breather hoses (found under the starter cover) are already discontinued.
