Great to see you've emerged from study, hope you went well.

I'm finishing a job on a big Gixxer ex racer turned street bike. It literally has more than twice the hp of my Monster by quite a margin. Test riding is interesting.. Oh dear! [leo]
The Monster is more fun on the street.

That Gixxer probably has triple the air box volume of a carburetor-ed Monster with the velocity stacks at one end and the air filter at the other after the intake tubes for the ram air. There is a huge volume of space in between.

I will have the Monster on the dyno soon.

Awhile back I acquired a set of the Febur / CM Composit carbon upper "intakes" (these:)




...and eventually I'd like to work something similar to (here's a three-way combination for you):

(1) BMC 748/9*6/998 Air Filters Set-Up:


(2) Streetfighter "Ram-Air" Carbon Intakes (mine in the form of the CM Composit Intakes I've got)



(3) Jako Airbox for split singles


("4") "END Result" similar to: Bursi Evolution Carbon S4RS Airbox with Ram Air

fun catching up on reading this after being away for awhile; that riding house ram-air lid is bfa! One day I will master fiberglassing/carbon-fiber'ing and make some type of gonzo airbox for my 900

you can do it easier than you realize.  there are some great videos on youtube.  i made a mold for the stock airbox but broke it accidentally when moving.  I should try it again.  Even with plain fibreglass it is going to be around half the weight -- no reason to use carbon unless you just have it lying around.

"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.

Hey you're onto something, I've got a couple of daughters who want a Monster for their first motorbike! :D

I was thinking of possibly making a carbon shroud to shield the pods beneath and each side to calm the air a bit and keep out water. Since the pods flow enough air to support over 100hp, the largest barrier to 100hp is now lack of valve area and the long manifolds. A beaut air box would just add to the performance, and most likely right through the power curve.

That is a very interesting set up you are looking at j v. It is going 10/10ths to extract all the available performance for sure, which must be why Jako went that way on their racer.

How to mold something with enough volume to fit a Monster with all those frame struts will be interesting. The struts relocated to allow for split single FCRs could give the room you need, more like an SS. Notice on the Jako site there were only SS bikes with split singles?

The split singles on short manifolds may come when I do the next full refurbishment including painting the frame. Then I will do the full MBP style heads with big valves and raised ports. Damn it that I prefer the look of the older Monsters I only want 100 air cooled hp!

Yep.  Buy all your toys and extras before you have kids.  Once you do, you better win the lottery because time and money are not in surplus anymore.

i'm trying a variety of delay tactics.  among them, moving 600mi twice in 3 years and getting a ferocious house cat.

Update.
Had to delay dyno test due to the dyno requiring a service and rebuild. I am concerned that having been refreshed, the dyno may read different. Have a booking for next Tue, so will report back then. I will discuss with the dyno guy whether the dyno rebuild will change the readings and if so by how much.

Honestly, I don't expect there to be much difference between pods and an open air box, (for old two valvers), as long as both configurations receive the appropriate jetting. But that's why we test things. We'll see.
