pilot screw initial setting for 40/128 jetting

Like your feeler blade, I've also seen it done using a couple of bits of thin wire, such as a guitar string. Maybe a B or an E...?

Ray…Still need to know if it’s an ABS/Emissions bike to determine carb settings. I need this first.

Ok, this bike is a mess from sitting for years in the Florida heat and humidity. The green you saw is fermented rotten ethanol. Many “aftermarket” changes have been made to the bike all at the same time, with little to no results. Plus, two separate guys have worked on it, doing separate things. This may take a while to get straightened out, but we will…

Fresh airand fuel filters?
Have you spent the time to synchronize the carbs precisely? If not, do so.
Does it still have the auto fuel vacuum valve? If so, bypass it, take it out and throw it away.
Go back through your work and the rebuilders to triple check that EVERYTHING is secure and put back together properly.
Did the eBay carb rebuilder give you any specifications on what changes were made and how the carbs were set up?

Can you point me to remove and bypassing of the auto fuel vacuum valve? Thanks, again.
