K&N air filters for 35mm Keihin FCRS?

BrianK said:

Anyone know what K&N filters would fit these? The originals on mine need replacing - they are oval-shaped and an incredibly tight fit. Shoehorned them off and on once too often and did physical damage.

I'd like to replace with somewhat smaller, and ideally round-shaped filters. I just got them back on; covered with grease and sweat and realized I'd forgot to note model number or to measure the carb spigots they clamp onto. Don't have the heart to do it again, at least not soon.

I did reach out to Matt Rambow at CNW and he may be able to help, but hoping others may be able to chime in.

At a cleaning interval of 5 yrs or 75k miles at least you’ll not have to remove them again anytime soon and I’m grateful that Matt cleaned mine before shipping cNw #101 if they are that fiddly

Thanks. That looks like the ones I have on there - too big for available space. But I see the flange measurement is 2", which is helpful. Tx - B

That's the issue! Rob do you by chance remember where you got those adaptors?

Here is a photo of them fitted - gives just under 20mm clearance from the back of the filters to the battery tray plate.
No problems (now) in removal and fitting filters!
Cheers
