K&N

Hai!

 

I'm searching for the part number of the two air filters that are directly connected to the cylinder.

I think that there are actually 2 or 3 models out there that will work, even some very small cone shaped K&Ns that people have fitted. But I think the cylindrical ones as pictured, and like mine, look better and provide more surface area.

 

You might try www.guzzitech.com for more info on filters as well.

 

 

I don't have the part number for the filters you show, however if you check out my thread:

 

Pods versus modified airbox lid thread

 

The filters I used are K&N model: RU 1780

 

And the advantage(in my opinion) of the filters I've used is that they already include the "intake runner" and are angled so that they hug up against the bike better than the straight ones as you have pictured above. Although some may disagree, the conventional wisdom is that one shouldn't hang the K&Ns directly off of the TBs, and instead should cut/use the intake runner to attach the filter upon. However, as I mention, some of the newer K&Ns have an extended flange that is essentially the same thing, so that the OEM runner and rubber gasket is no longer required. This is what I have on my bike.

 

Hope that helps.

From my website here is some information taken from various sites:

 Seperate Filters for those eliminating the airbox.  

 

 

For those keeping and modifying the intake tubes from between the airbox and the throttle bodies a 2-1/4 inch filter works well:

 

K&N RU-0600

round, non-tapered, straight flange

flange: 2-1/4" (57mm)

width: 3-1/2" (89mm)

length: 4" (102mm)

  

 

For those connecting directly to the throttle bodies measure the outer diameter of the throttle body to match a K and N filter.

If anyone knows if some filters fit better, let us know.

RU-0600, that's what I've got on mine. I couldn't remember while I was at work.

If you can use Al's version- and not cut the intakes- that's probably the way to go.

For what it's worth, the stock filter element can be replaced with a K&N 33-2682. I got one for my California and found it to fit the V11 LeMans as well.

The throttle bodies diameter is 52mm,

gives you som choices from the K&N list.

Personally I prefer the look of the conical filters

(K&N calls them "Tapered").
