Got it.  I thought it was based on the M8...sorry.  If you do a V2 on an M8, don't forget to ask them for the 2" and longer stand offs.  Also, you do know not to charge the V2?

I have this same AC on my blue FXR (TC124) and was prepared to draft a lengthy email explaining how the outer plate interfaces with the standoffs. But since already have the filter you see what is needed to use a taller filter. Seems about half an hour on a lathe and a taller filter are all that is required. That stack looks cool, not sure if it adds anything though.

Regardless what K&N or anybody else says, the filter flows less as it gets dirty.  If you've got a real "breather" of an engine a little extra width might give extra margin between cleanings as long as it's not in your way.

Additionally, one feature I like about the V2 is that it's very easy to clean in the hotel sink when I'm on a long trip. If the bugs are bad, I'll clean it every few days.

Some follow up on the V2 breather for the Twin Cam motors. As has been known the OEM size filter is a K&N E-3300. Below I'll list the three other K&N numbers that are taller and match the ID and OD.

Part    Height     ID     OD
E-3300   2.750   5.250   6.250  (OEM size for V2)
E-3340   3.250   5.250   6.250
E-3344   4.000   5.250   6.250
E-3346   6.000   5.250   6.250

I ordered an E-3340 from K&N which is 0.500" taller.


The filter stand offs in the Twin Cam filter are a length of 2.550". I'll need to make three that are 3.050" long. But will wait till the filter arrives to insure the length difference. 

I may also go ahead and make three that are 3.800" long in the event I wanted to go to a 4.000" filter. But I don't see that being needed or of any benefit.
