Re: My CM400T Cafe Build - Now a CMB400 Frankenfe
Thanks gr _yamm, progress has been slow considering I started a second build before finishing this one. I have pulled thehead and have cleaned things up, just inspecting prior to re-assembly.
Regarding you question on pods. Typically I think guys put these "pod" or "cone" filters in for a few reasons
1) In the quest for Improved Performance with exhaust modification
2) Visual Appearance - Visually open the frame up (This desired "Race" appearance was born from the quest for #1 above Better Performance)
This is not a difficult project ialone (but typically done with other modifications) the hardest part asI recall was getting the old air box out of the frame, it requires the rear tire be removed to give access to remove the air box. (It comes out through the rear of the frame and the tire will be in the way)
There is nothing to fabricate to install the pods/cones. Measure the end of your carbs & buy the correct size to clamp onto the end of the carbs.
As I mentioned before this modification (on a motorcycle) is really an attempt to improve perfeormance, and done along with a free flow / less restrictive exhaust and rejet of the carbs. theory being get "more in & more out"
On these particular bikes guys usually get rid of the big cross over muffler (Below the engine) and install straight pipes or a 2 into 1 exhaust. Since these particular carbs have very little options in rejetting, I understand this can be challenging.
Since this is your first project I would recomend you stay away from this for now, plenty of "ugly" to get off these bikes before loosing the air box. A very clean "Cafe" style bike can be had by changing:
Handlebars to Euro, Drag, Clubmans or Clip-Ons.
Seat to a cafe style or low brat style
Fenders bobbed or removed
Gauges tightened up and lowered.
Mirrors to short stem or bar end.
Loose the Center Stand
Lower Headlight
I started a thread for these post CB/CL twin bikes it currently has over 50 links to other builds of these bikes on the first page. Spend some time there I think you will get some idea. here is the link

frankenfe,
I love your bike, and I'm new to all these types of customizing and conversions. I just picked up a 1981 honda cm400t, and I love that stripped down look you have. Is it really that simple to replace the WHOLE airbox assembly with an a conical air filter? I'm really considering doing that, but do I have to make custom intake manifolds or anything? Or can I just take out that whole airbox assembly and replace it with a K&N filter??
Thanks and love the build!
