So I'm having trouble lining up the rear boot from the surge box. Front carb lines up perfectly, both carbs are set correctly in their intake boots and the intake boots are in the correct position on the heads. The rear boot seems to be too long. I try to force it on and the inside portion is far from being mounted. WTF! Any ideas?

Check the repair manual. One boot stays on the head, the other stays on a carb.

Edit: I'm not sure which boots you're talking about, but the ones from the head to the carb go on as above. I don't recall which one stays where.

I'm questioning about the boots coming from the air box. The boots on the head to the carbs are positioned and hooked up correctly. Carbs are centered and secured fully. Just can't attach the air side of the rear carb. Fuel side is all good.

When I removed the 'snorkels' from my 750 to get to the carbs to clean them and found so much frustration with just removing the ducts, I said, "Forget this!" and went with the full ear shave.
I have never regretted it.

Did ya happen to notice they are different and one says R and the other says F? Cause you have them backwards. Assuming of course that you do have the pins aligned on the boots going to the jug or it doesn’t matter which hose you use it’ll never be right.

Forget if they're both the same... Any chance they're reversed? Should be flexible enough to go right on if they're close.

Never had to put mine back, earshaved the first time. I'll take a look at them later today.

All 4 pieces are different. All 4 are keyed with peg marks where they line up. If a single one is off the mark or the front one is in the back it wont work.

Here are the pin marks on the boots that connect the carb to the jug which must be lined up. Correct orientation shown in my pic of the manual a few posts up. Also, this indention for the rear oil feed is the snorkel for the carb on the left side of the bike. The small indention is the left snorkel, the larger death star indention is the right carb snorkel.

Sorry guys, when describing the surge box boots I guess I should have been referring to them as snorkels. My intake boots are in the proper place(I.e. tab on boot to mark on head). I'll try to take a picture of what I'm talking about on Monday when I get back home. My right/rear side "snorkel" is sticking out about an inch too far. It clearly sticks out more than the left/front side but the surge box hasn't moved.

Are you referring to the short ducts that connect the air filter boxes to the surge tank?
