FCR install-does everyone use pod filters?

From the instructions, it sounds like a really straightforward install.  And should be.  I've altered the airbox in the carb 'pulley' area, but when it's come time to install the airbox and intake boots it's become a PITA.

I've tried the boots first on the carb mouths, then slip the airbox over those.  Then boots on the airbox.  What I'm running into is that the carbs just seem to be in a slightly different place which doesn't allow me to slide the boots over both the carb mouths AND fit them into the airbox for a sealed fit.  They appear to be 4-5mm too short.

There is a small 'guard' around the carb pulleys I could grind down, as well as hack into the airbox further.

Has anyone done the airbox as part of the FCR install?  Or have you all resorted to pod filters and a separate battery box due to the hassle factor?

I believe the majority of people actually use the stock airbox, I did.  After you hack off the parts that you need to in order to get it to fit around the pulley area, it should be pretty easy.  Some people have mentioned difficulty with the boots, but for me, I put them on the carbs first and the box slipped right over the top, no lube, no problems.  Just a little bit of kneading and it was done.

were you able to get the airbox back into the groove in the boots?  I think that's where I'm getting hung up and it appears short.

Yep they should fit back on just as before, make sure you take a look around to make sure it isn't hanging up on anything, and put a little pressure on it, you should be able to pull them through until it sits how it was before.

I used the airbox. The rubber manifolds seem too short but they will go with a little stretching and kneading. Make sure the rubber manifolds on the engine side of the carbs are on properly too.

Ive used both on my Monsters and Superlight. Currently went back to the air box on the Monster. I leave the boots/velocity stacks clamped to the carbs. I have also shortened the velocity stacks so its even easier to get them on. Make sure you haven't pushed the boots down too far on the carbs robbing you of a few mms.
The ignition switch/steering lock can get in the way too.

Another thing, I seperated the battery box from the air box. This has made it much easier to remove either and for general servicing. With the battery box section out of the way, dealing  with air box removal/fitting is much easier.

I was thinking of doing that very thing. Got any pics?

+1 I was looking at making an overlapping plate and riviting it to one.. curious to see what others have done.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

I just cut at the join between them, nothing fancy. I used a cutting wheel and a dremel type tool to remove some extra material above the carbs on the air box to give better access to the carb tops without having to remove the air box. Also made a gap for the plug leads between the a/b and battery box.

I've done all of the above.

The best set-up for power was stock airbox with the lid off. The best looking set-up was ditching the airbox (in which case I started with the battery box chopped out of the stock setup, but eventually made my own battery box out of AL)
I own several motorcycles. I have owned lots of motorcycles. And have bolted and/or modified lots of crap to said motorcycles...

Done all of above. pods are the simplest, they work great if you're
keeping it below 110mph..

i think i just leave the rubbers in the airbox and put the airbox on.  can't say i've had an issue getting it on that i can recall.  if you do use a pod put some sort of bellmouth inside it or get a pod with a moulded in bell.
