Tom, i will thoroughly read the link you sent me. Then i will email you any questions i have. Thank you so much for your comments. I don't want to leave any stones unturned !

Steve!

A hearing impairment makes telephones difficult for me, but you can always email me direct at libertynightshift@gmail.com

A big rubber stopper gets you most of the way: http://virtualindian.org/11techleaktest.html

Although a testplate upon the manifold is most convenient, a stopper is the only way to test the inlet nipples separately.

Any stone unturned hides something that will bite you...

Tom, i appreciate your sequential order of identifying the appearance of fuel mixture burn on each spark plug to diagnose air leaks. No, i did not bubble test. I would appreciate being able to talk with you on the telephone. When could i call you ?

[T. Cotten]

Steve!

As Harleytoprock reminds us, injector cleaners and other fuel additives will make plugs appear lean even when in perfect tune.
So much color at all means an over-rich condition. This is often because the motor will not run any other way, because of a vacuum leak. And since your plugs are not equal, I would suspect more leakage to the rear than the front.

You bubble-tested your manifold assembly, right?
(Had to ask, sorry.)

Steve, Congrats on the maiden voyage!!! With today's gas, spark plug reading is a thing of the past. Best to tune for best running and error a little on the rich side for a new motor. Also for a new motor,I like to add 6oz of synthetic 2 cycle oil to each gallon of gas for the first couple of hundred miles. Have fun and best wishes!

Thanks for your comments on today's "gasoline." i'm looking forward to a test ride in the country where i can ride any distance necessary to get my carburation adjusted.

Steve, well done in resurrecting this bike. You must feel tremendously satisfied to have got to this milestone.

here's pics of my ft/rr spark plugs. i'm more interested in hearing your comments what you think of what you see than what i think i see.

Slow speed needle set at just under 7/8 turn from fully closed.

High speed needle set at just under 1-1/4 turns from fully closed.

Yesterday was a day of major excitement after 30 years of dreaming about this moment and 35 months of getting this old fellow ready for this moment. So yesterday, i just HAD to KNOW how the bike would do, going down the road, even at least for a few minutes. in my area, there is NO roads with low or no traffic, to do any decent test riding and bring tools for any required readjustments. So, i pushed the bike 4 blocks up to a quiet neighborhood that has a modest 1.1 mile loop. As it turns out, the 2 brief rides including riding back to the shop were exactly 3 miles according to the Corbin speedometer. That being said, my first 1.1 test loop was not videoed and went well, the clutch would disengage to shift in to first gear. after a brief cool down and this loop to be recorded on video, after the start up, i was not surprised but a bit dismayed the clutch would not disengage enough to shift into first gear. So there was some knashing of teeth. That being said, i deleted the previous video and posted the below edited versions.

It's really good to have this initial ride done, the bike's back at the shop on the lift. We'll be ready for more extended test riding after I've done some readjustments.

My plan is to wait for a cool day, probably towards Fall, then head east with my tools to remote country road and spend the better part of the day riding the bike, letting it cool down, make the necessary adjustments during this fitting in and break in period. Having a piece of quiet road where i can ride a distances necessary to get the carburation adjusted properly will be really nice.
