I replaced the air filter on my Skorpion today as part of a service and it made me wonder what the value of the air scoop is and whether it couldn't be removed with imunity? Also does anyone know which K&N conical filters fit the standard carb, should I decide to get rid of all that plumbing entirely?
Many thanks

Hi,
The snorkel on the airbox is usually removed when racing with the stock box.This allows more air in supposedly,Mine has been off for years....
The K&N #s that have been used are RC1250,and RC1820..these were originally used for the SZR. Mark in the Netherlands uses 1 each.
There are some articles about using a Honda Civic 1.6 airfilter k&n # 33-2120 I think,cut down and siliconed to the stock frame as a replacement filter
Hope this helps...by the way using the honda filter will give you 2 filters for the price of a single RC1820.....

i cut out filter paper from original filter and replace with foam from a sheet they use in trail bikes
and the rubber cover is missing on mine
mine had the air box cut off and stack filters
i put it back stock
i was having problems when in a hard rain storm
the carbs were sucking in water
and making bike run bad
my way to solve the problem of bike being to slow is buy one with a bigger motor
as mods seem to not make it go faster any way

you can remove the snorkel without any consideration.
Peak performance is slightly higher with the thing but the power band is much narrower and adversely effected in midrange.
The airbox is much too small and the frequency, such as it is, that you do get can only be high so that, if anything, detrimental to "normal" engine speeds. By removing the the thing, the box is even smaller which should raise the resonance even higher but by "making" such a large hole, you a tually lower it and weaken it as well.
The only "unwanted" side effect of removing the thing is that the bike is louder.

Bill,
I gather then that removing the airbox and using pod filters is a better approach? I know Andy Driver has made his fuel tank his airbox on his Supermono.,and moved the
fuel to under seat..
