Graham is 100% right. Every bike is a little different. I have had similar builds that have had completely different jetting.
Always love the “la grosse patate” The Big Potato! Hahaha
With the SHA and French bikes they can be touchy. Are your running the screens and the plastic cover? There is a lot of air restriction there. A good friend of mine, who has way more patience with French tuning then I do, will get the jetting close then remove and add screens until he gets it just right. I am lazy and just usually pop out all the screens except 2 or 3. This way it is still blocking some of the dust and dirt. I have even just said forget the screens and ran just the black cap. I don’t really recommend that because it is just deflecting stuff at this point, but sometimes I don’t care.
But back to what Graham said, don’t listen to naysayers if your temps are fine and plug chop looks good. All bikes are different to some extent. Some people have air leaks and don’t know it or they are running a old SHA with a terrible shim that is letting in a small amount of air all the time....and maybe emcee an ovalized intake from taking the carb off all the time. Keep messing with it. You will get it right. French bikes are finicky, one small adjustment may make all the difference.
Oh and you really did a nice job putting this motor together 👌🏻
