they are an alternative form of airfilter..instead of having an airbox mounted to the carbs and 1 air filter, you have no airbox and 4 filters shaped kinda like cones which are mounted directly to the carbs.

I have seen what look like K&N cone filters on a number of bikes on this forum. Who makes them? Do you need to rejet?

[Iceman71]

K&N is the manufacturers name, a bike shop is the most likely place to find them as regular jobbers don't seem to be able to get them. As far as rejetting goes, I am pretty sure that you will have to as air flow is critical to bikes and any change you make at the filters or the exhaust generally require a rejet. I think they may also offer a kit with all the cones plus rejetting instructions..I will see if i can find the page again and let you know

Thanks for the info. I will put this on my list of must haves after I get this thing running.
