Is the mesh functional? Does air flow through it? Or is it solid behind the mesh? I don't care about the brass bit, but I need an air cleaner cover that will keep out most of the water when riding in the rain. Doesn't seem like there are ANY aftermarket airboxes that do that.

Decorative, only.
I'm with you, Charles. Rain is why I haven't bothered to change the air filter / intake.
If a ham can cover from a Sportster would fit over a K&N unit, it'd be close enough to stop a lot, especially when parked.
It's still a K&N, though.
They simply don't filter out dirt as well as a good pleated paper filter & rely on dirt settling onto the oiled fibers to create additional surface area to catch dust & dirt.
Until then, a lot makes on through. =(

Well, with more than 11 horsepower to uncork with an Ivan ECU and an intake, it's worth putting time and effort into an airbox. I just really would like something that protects against water ingress. I ride in the rain all the time, and this scrambler will be taken off the beaten path and down fire roads on occasion. I want something with more intake than stock, but also something that wont drown the bike if I get caught in a monsoon. Or worse, a monsoon hits while I'm in my tent or in a hotel, and the bike is just sitting there on the sidestand, cylinders getting rainwater in them. Not a fan of that.

A rainsock would fit over many of the options available (V&H VO2, Cobra) etc.? Failing that, Low and Mean make an adaptor for the Bolt that they say allow it to take *most* HD air filters and covers - surely you'd be able to find something to your liking then?

I questioned K&N regarding a prefilter or rain sock for their air intake that I got for Xmas and they redirected me to Outerwear Inc. but they unfortunately do not make one for that particular K&N intake. However they do have the option to order custom sizes which I have yet to investigate.

Did you get the RK-3940 (same as the one on the 'Super Hooligan' bike) as that's the one I'm erring towards?

I'm thinking if I get the K&N intake and filter, I can insert a thin piece of aluminum bar along the top and leading edge of the filter. That would block off about half the filter, but it would keep the rain out. I'm unsure how much this will effect breathing, as it's still a lot more intake area than the original airbox has.

Yes I did get the same one as the Super Hooligan bike. Haven't tried it out yet. I changed the four screws that hold the front cover from being small button head Allen screws and went with hex heads. They are behind the assembly and are hardly noticeable. The small Allen screws were a real struggle to deal with. I also reused the existing breather hose by simply rerouting it and trimming a bit off the length. The breather hose that comes with the intake is ridiculously stiff. I saved the trimmed piece of hose so I can easily switch back to the stock intake by using the splice fitting that came with the stiff hose!

Noted, ta. You don't fancy picking one up for me Stateside and posting it to me as a 'gift' do you?! ;-) They're nigh on $300 over here, so for that reason alone I may look elsewhere (if I can find any power figures for any of the other recognised filters - K&Ns are the only ones I've found easily)

Powerwise it wont make any difference. All the namebrand aftermarket intakes for the Bolt use a K&N filter.

They might use K&N for the actual filter, but they vary greatly in exposed filter surface area, Venturi design etc. which I think will make a difference with how they perform.

Example: I had my Harley Dyna tuned by one of the top guys in the UK. Hot cams dropped in and everything. I then went with the traditional S&S teardrop filter, as I liked the classic look. He said, with his experience of tuning with those cams, it should have made more power than it did, and that it was the air cleaner holding it back (he kept pushing a Forcewinder or similar).

Now, granted, on a bike that doesn't make 50bhp stock, there's less to fight for, but I'd say there's still a couple of ponies difference depending on what air filter design you choose.

Thoughts?

I think you've answered your own question. One or two horsepower...Is there a difference? I cant see a difference. I installed the aftermarket intake and pipe solely for asthetics - looks and sound. If Ive gained a few horsepower great, so be it. But honestly I really can't tell, maybe a few mph top end. NOW, when they come out with a turbocharger for the Bolt, THEN we'll have something to get excited about.

Yeah, don't hold your breath.

Personally - if air filter A performs better than B (for similar £'s) I'm going with A (and they all look better than stock).
