Carb Isolator Boots

Carb Isolator Boots
I think a few things on my bike were not put together properly ages ago. Any torque worthy bolt takes a strong arm to remove, brake slide components did not have a healthy amount of grease, starter solenoid connectors had poorly crimped ends, etc. I'm sure there will be more...
Anyway, I'm getting at replacing my carb isolator boots and it looks like those may have not been put on correctly as well (Maybe causing my suspect vacuum leak?). Every one has a different "turn" on them. None of them look straight. I don't see any type of guide on the cylinders that would indicate where they should set in, except for maybe a bump on the inside of cylinder 1 and 4. I did notice the "MM5L" and "MM5R" marks on the boots themselves and assume that is the top position for outer left and outer right boot. There are also forked tabs on the side of the front facing rim. I'm heading to bed soon and will read through the service manual in the morning, but I figured I would check if anyone had some "yes I did that" advice to put me in the right direction.
Left bank orientation - I already removed the right bank so no photos.

If anyone has a photo of the factory position that would be good to have.

If you look at the position of 1 and 4 they are correct, except they are upside down. The screw heaads are angled propperly but they should be on the intake side, not the carb side. So 1 and 2 should be at the same angle, pointing out towarda the left side of the bike and 3 and 4 should pointing in the equal but opposite angle so the point out on the right side.
Also, it's easier to mount the boots on the carbs 1st the fit everything down onto the intake.
Hope this helps. If I need to take a pic, I can but it will be a few days probably

Thanks hamlin, I won't be taking the carbs of again for a while (They passed the spray test, no idle changes) but a pic would be good when you have time for posterity's sake. I'll put them on right next time the carbs come off, with brand new clamps, and maybe someone will need this info themselves someday. I'm not dumb (and not overly smart either lol) but I have a tough time with things when they are not right to begin with.
Also, if there is printed documentation that tentacleslap provided regarding the notches I could not find it. Maybe it's in the Honda Common manual, I didn't check there. Knowing that beforehand would have saved me a lot of time, so it's nice to have this info on the forum.
