RAMAIR Filters bespoke Rocket-3 underclaw filter.

... and the RamAir is now installed. The detailed instructions made this task a piece of piss. Thank-you Mr RamAir.

Installation of the RamAir filter and relocated air sensor was quite quick. It took about the same amount of time as it takes me to lift the tank (fiddly gauge bolts and hex spanners that are too short). Admittedly I already had pods on the bike so I didn't have to spend time removing the standard plumbing.

Loaded my new TuneECU map (thanks @HansO) and let the bike run through the 12 minute tune. First test ride will be tomorrow (hopefully), when someone stops lobbing cats and dogs my way.

Didn't get around to installing the crankcase breather that came in the RamAir kit. Everything was still hot from the 12 minute tune. Will tackle that task in a day or so.

make sure you don't go riding in the rain without that crankcase breather or you'll be needing an oil change

It is still connected to the old breather hose.

Oh good, you had me worried for a moment!!

Ha Ha ....sorry I had to laugh the RX 4040-1 filters stick out about 3 inches past where the b/claw sits, you have to cut most of the bear claw away

There is one other option you may consider the unifilter's NLR fitted to my R3 before the Ranair was out , Nev say's these breath a little better and fit under the bear claw they get pushed a bit by the bear claw though

Thanks for the info.

I rode about 90+ miles yesterday without any air filter. I noticed the "chirping" as certain low-load, low rpm situations. For all the harping of earlier posts, I didn't find it that annoying.
This morning I received this reply from Bob Carpenter regarding my lack of air filters:

"We don't run air filters. We have the proper velocity stacks on the throttle bodies. In our 40+ years of building high performance street bikes, we have yet to see any faults without air filters. The engine will eat bugs and dust without a problem. Try not to follow gravel trucks. There are K&N filters available that have an open filtered top along with the perimeter, that don't show very much power loss. However, you'll have no bear claw and they might get in the way of your left knee. We strongly recommend you leave as is. Hope all is well."

I assume he may be referring to the K&N's that HansO runs. As for me, I will be getting something -RamAir or perhaps the NLR's. Maybe I'll just tie a shop rag over the stacks!

As for following gravel trucks -not something I do while riding or driving.

I wish there were some others with Carpenter bikes here that could tell me what (if anything) they've done.

In the mean time, I'm riding!

Do you happen to have a part number? I've searched "NLR" with no results. Also, did you clamp/zip tie these directly to the throttle bodies, or is there a velocity stack hidden under the filter. This I.D. and length dimensions would help as well (if you know them.) Thanks

Well, I just got an answer from Eric Carpenter -I had inquired about what they thought of the RamAir filter:

"
Hi Bruce,
The Ramair filters are too restrictive. We had these K&Ns on a bike here that only lost little power when installed:

So, now I'm looking at the Uni Filter line...
