Hi Uncle,
I had disconnected the stepper motor and plugged the 3 nipples with silicone plugs, The throttle bodies are connected to a T fitting. I have the vent hose from the front timing housing connected to the T with the other ends going to each throttle body. Therefore the blow by is re introduced into the combustion chambers to be burn off.
The engine rev's so much quicker since it now is gulping in a lot of air and exhausting it with very little restriction.

Hello Popeye,
The ability to do this is just time with a bit of money. The battery box is of my own design. It is carbon fiber and is holding up very well for a prototype. This box is not yet available to the public as I am underway trying to get a patent pending on it as well as having a specialty shop fabricate the final product. I am looking to have it to a shop very soon.
Everything else is just buying the item needed. The separate filters the T section and make certain you follow the correct path of the breather hose.
Time wise a few hours since you may have to remove the fuel cell, which is easy to do.
If you need any other assistance just ask. I am always willing to help.

It really runs out real well, rev's much quicker than with stock components by far. This is not only my wording but a Guzzi mechanic with over 25 year knowledge.
Bike runs real strong.
The filters as you see are K&N round filters.
Allow me to get the proper numbers off the filter. and I will get right back to you.
When replacing the filters as I had done, please know that once you remove the airbox/battery tray you must have a battery box to hold the battery. At this time I am working on having some made off. My prototype that I am using is carbon fiber, the shop who is working with me to build a perfect mold for me said that carbon is an over kill and overly priced material and they suggested using a high grade fiber glass wich will keep the cost way down unless the buyer is into spending lots of money on carbon battery box that won't be seen.
If interested in buying a battery box, let me know.
I will get back to you about the filtres in the next few days.

Doug, nice adventure... I revised/fixed/combined the photos into one post for you above.
Here's my (dyno-proven) findings regarding power gains with pod/separate filters -vs- air-box debates over the last decade...
1. Normally aspirated motors prefer "still-air" plenums... opening the air-box lid showed measurable gains on the older Calis as seen below. Eraldo @ Fast by Ferracci made the ring linked above because it showed the best gains, over pod filters. Separate/Pod filters showed less then above throughout the rev range, and finally caught the gains afforded by the open-lid air-box only at the very top of the revs.
2. It is best to leave the connectors (velocity stacks as shown below or OEM plastic versions) on the throttle bodies, to smooth the air-flow from the filters, for those who go this route. Dave @Sport Cycle Pacific in Santa Barbara, CA offers them up (still it looks like) $99 with Uni-foam or $150 w/K&Ns. Click pic for details:
Doug, might I save you the time and money on a patent... don't bother, if you find even a rare few that are interested, half of them will make their own. Their just aren't enough Guzzis around to make it worthwhile.
Also, if you haven't seen... If you're interested in making it fuel properly, see the PC-V/ECU swap HERE to get on board for the limited run.
Closing with... "runs real strong" needs to be backed by dyno-data. Costly, but the only proven way to show it, as feel is more often deceptive then not.

here's a link to a post by a french member who's been doing a bit of similar work on his Breva, augmenting air intake by removing (I think) the airbox muffler plate, K&N filter, but also a polishing of the air intakes. Which were quite 'granular', see the pictures. He claims it improves smoothness at low regimes. As to the 'Brisk' plugs ... snake oil?

The machined aluminum is great looking but there is only a certain amount of space and if you add a battery box for the Griso which is a must since there is no battery support when adding the separated filters. Where are they mounting the air temp sensor? Where are they mounting the fuse holder? What are they doing with the blow by hose? With my design, everything is thought out and works. Besides UNI filters is your bike burps back thru the throttle bodies, they singe or burn. We have seen plenty of toasted UNI filters. they are good and they work well.
There is a new filter company called Green, but they are ultra expensive
I have dealt with FBF many times before since I only live 72 miles from the shop with a good friend 6 miles from the shop. FBF likes to fudge numbers and with his reputation I don't trust him. I do know Larry, he went to Drexel U in Philadelphia for accounting. Business and to make money is their objective not to help anyone that is trying to make a few buck here and there. I would run my Griso up against anyone of their Griso's anytime along as they have not done the head work and as you know this is where power is made.
I thank you for your input is is very much appreciated, but again like others I am trying to make a few dollars here and there since my Marine Corps disability pension has me rated as unemployable so therefore I am stuck with a small income and I need to subsidize funds with a great idea. My idea works and works well. If no one purchases that Okay, at least I have the only one in the world with my box design. Now I stand out from all the rest. This is why I didn't buy a Harley I didn't want to get lost in the crowd.
So, again thank you for your response and it is appreciated and respected.

Hey LondonRob
Could you expand on the catch bottle mod. I'm guessing it doesnt need to have much volume and also that it isnt totally sealed
