Welcome back to VFRD after its little vacation. Hispanic Slammer, thanks for keeping the forum up to speed - you're efforts are appreciated.
To purchasers of headers:
Duc2V4 and I are unable to access PMs at this time, but we are getting email notifications when you send a PM, and we can read what you wrote. Until VFRD is back to being a fully armed and operational battle station, you can email us at vfrheaders@gmail.com. A few of you have already done this and it's working well as a stop-gap measure.
K&N's large aperture [big mouth] air filter with part number HA-8098 is the only one they currently make for the VFR800. the big mouth is the filter we installed for dyno testing and tuning of the prototype headers.

Confusion ensues because K&N on their own website and online retail dealers of K&N products all feature photos of the now defunct small mouth filter. Yesterday I ordered an HA-8098 straight from the K&N website and today a big mouth air filter arrived. I will attempt to attach a photo of the filter that arrived today:
