Breather mod

Good day to all out there in VN2K land and thank you in advance for any feedback. So here it is, I've been looking at the tightwad open element breather mods on the new, improved gadget site and was wondering if anyone with one of our machines had done this. Everything I've googled or searched on various forums hasn't given me any info for the vn2k, just Nomads, ect. Any input, such as possible need for fuel controller or other headache causing issues will be appreciated. Scoot it an 07 VN2K LT. Only mods to date have been Poncho's marbling mod, and double darkside. ThanKS

The most common breather mod on the cheap is to remove the secondary butterflies to allow more air in.

Thanks Rod. I've loved the looks of the Spectre short cone breathers forever and fabbing a mounting plate wouldn't be any issue. I truthfully hadn't thought of the secondaries and will give them a look as well. Haven't had the chance to tell you but I like the look of your scooter here lately.

Does the secondary butterflies really allow more air in..or does it stop the bike from choking itself...which would be almost the same thing

Anyways, if you haven't done the secondary butterflies, yea, go ahead and do those. It will allow a more constant airflow.

Yes, I'm a Chrome Whore.

She has been a labor of love. I have been working on her off and on for over 5 years. Some mods I did just to see if I could ;-)

Deleted the secondary butterflies last night, got a subtle whistle now when cracking it, almost like a turbo. That right? Anyway, also saw it's due a breather element so rather that pay stupid money for something that can't be washed I'm gonna go ahead and bite the bullet and either fab a new one using a short spectre, or e-bay it with a breather kit.

oh yea, 'bout to forget, too many hard licks to the head, but anybody here had any experience with the new Dobek EJK Gen 3 fuel controller? Had a gentleman on the vulcan riders facebook page strong recommend them.

Had an older TFI on the Nomad, liked that it was manually adjustable never had to worry about "loosing" a map.

Looking at dobek's website the gen3 basically learns as it goes. your inputs into the system can literally be done on the fly (not that anybody would do such a thing).looks like something I'll have to keep in mind.

I think you'd need the GEN4 setup with O2 sensor for auto tuning.
