I am looking for advise on flopping my carbs to face outside instead of facing inside using the airbox.  It looks like to me that I would have to make adapter plates on the in-take manifolds.  Has anyone done this before?  Or is there a kit I can buy?  I have already eliminated my pair valve and emissions and blocked off all my vacuums.  also have changed out the gas peck rooster valve.

email is charlie.staub@yahoo.com
Thanks

I'd advise strongly against it due to the problems in getting any kind of laminar flow of air into the carbs. The air rushing past carbs at 90 degrees can be a bear to sort out without some kind of baffles. Even the old 750 inline fours got tricky when running cone filters and really bad news with unscreened velocity stacks. Just moving your legs to the wrong position would affect airflow on the two outer carbs and the bike would run goofy. Then there's rain............

I have seen another setup with a custom ram airbox scoop to deal with the legimate points ¿spoom makes.

Those velocity stack bikes look awesome, but I can't believe they run too well at high speeds. Anyone got any info other than my guesses?  Wink Not badmouthing anyone, I'd really like to know how they run. Those are fairly deep stacks, which helps-I've just never seen setups like that work well even at 50mph.

That red bike looks like one that was in a Cruiser Magazine article. The article was "Custom Valkyries 6-cylinder Showdown"
You maybe able to find it online. Have seen another orange and black one, think it was in the photo galleries.

I'm more surprised that no one has custom build an air box that has ducts running from under the tank to the front of the bike.... like a type of "Ram Air" system... more MPH means more air...

Getting the ducts to look right and flow well might be tricky... but I'm surprised no one has done it.

If you get that to work OK, you'll have the opportunity to mod the tank to hold gas where the airbox used to be.  Could be like 10 gallons.  Or just install a fuel cell there and plumb it in.  If you had that AND a belly tank - wow can you imagine the range.  Or the fireball if you get hit.
