K&N Filters For Keihin CR 29mm Smoothbore's

[Jay1969]

Brand new preferably, if anyone can post a link to them or have them for sale.

Thanks very much.

Have a look at what this guy has for sale on Ebay

http://www.ebay.co.uk/itm/301156441169? ... 1497.l2649

I paid 97 quid for mine delivered from him - they are 150 quid most everywhere else. I could not find a better deal anywhere - and I can usually buy at trade. God alone knows why he is so cheap !!

Find your model numbers from here: http://www.knfilters.com/

Ignore the model listings, just find the correct size and buy those. The "XJR" ones were for my Rex.

They are genuine K&N. I bought to replace some shite pattern pods that had come with the bike. Not only do genuine K&N's look better - they work better.

Hi Charlie, could you measure the inside diameter on one of your
ZRX filters please. I sent a message to the seller in the eBay link
you posted, but he hasn't replied. I measured the outside diameter
on my Keihin CR 29's, and they are 50mm exactly. I guess 52 - 54mm
would be ok?

[Charlie]

Mine are 54mm Jay. They may be a bit big for yours. It does say somewhere on the K&N site how much leeway you can have on fitments.

You should be able to find a part number for the dimension you are looking for in here somewhere

The ones I have are in this section http://www.knfilters.com/search/UnivOvalTap.aspx

They do list some 51mm filters in there which may be better for the carbs you have.

Thanks for the help Charlie, I did find the K&N 51mm's ID this morning,
cross-reference number 1824, but when I measured the overall size of
the whole filters, it looks like it will be a struggle fitting them in, they'll
look awful stuffed to fit between the carbs and side panels, and the
spacing between each carb would be very tight too. Also the lip on the
carb mount is 6mm less than the K&N's mounting flange.
Keihin really only had their velocity stacks in mind for these carbs it seems!

Adrian H has found some gauze dust proof filter caps specifically designed to fit the Keihin CR stacks - available from Webike http://japan.webike.net/products/20878514.html
so I may as well buy them.

Thanks again guyz
