Bren down in Christchurch sells some neat anodised ones. Seriously considering one for the bucket.

The only thing I'd be concerned about would be water getting into the carb... yesterday I had to drain the carb a few times before races as my foam air filter/intake got soaked and water got in the carb.

I suppose it's a non-issue if there's no way water can get in though.

You have a hugger on the swing arm and an anti-splash cover close to the trumpet, you'd be okay.
Also maybe run some foam on the edge of the trumpet and just lean out the mixture a little for wet conditions.

Remember, your carb on the BADASS is sticking right out in the open and not under a seat etc.

Should be good for moving the power around if you have different length intakes you can test/change depending on the track.

thanks for the mention. Dangerous has fitted one to his FXR, and i have just fitted one to mine, they look BLING BLING and they actually do flow the air better, makes the air smoother for the carb intake.

Ok call me thick but for minimal power gains I don't get the open intake thing. I see it on a lot of US hot rods as well.

On a pure race engine that is getting rebuilt all the time - OK.

But the negative on a 'user' is all the shit sucked in that unfiltered hole goes straight into the bore and becomes grinding paste for the rings.

Unless you build a box around it and filter it or add a big foam sock.


Looks the horn though! :Punk:

easy way is to just put some stocking over the end. maybe dangerous can send us all his old ones.

Im experimenting with a cone made from sandpaper, this is to promote a smooth finish on the air before it goes into the carb, if you are worried about water getting in you can use "wet and dry" My first tests were with 80 grit at the trumpet end going dow to 400 grit just in front of the carb mouth.

I havet ever run a filter on a race bike
my bucket was pulled apart after 3+ years of bucket racing
3x taupo's
4x 2 hours

and there was no noticable damage from stuff going into the open carb
just a cracked piston from over use (bike was still runnning hard you could hardly see the crack in the skirt of the piston)

it's a race bike not a road bike and you aren't doing all that many k's on it
so there isn't much of a problem unless you send it into the dirt or gravell :doh:

Oh u smart! maybe soak the paper in water first so you not needing water at all, THUS expelling the water from the air

The clever guys in Auckland make their own fibreglass or CF stacks.

The real clever guys leave in the factory airbox and dont worry about it :shutup:

Would u do any carb adjustment for different lengths or just plug'n'play? How is power affected?
