i went and checked out a 94 ninja zx-6 today, and the guy pointed out these three little metal things coming from the rear of the gas tank (looked like there should be lines on them), under the seat, that were capped off. they put K&N filters on it and supposedly they go down where the fuel filter is or something like that (he wasnt sure, it was like that as long as he's had the bike). any idea where these are supposed to go?
btw this is the bike. it has ~9600 miles on it, think it's a good deal for $2750? there's also a '00 zx-7 around the corner for $3k, but i think an older 600 would be a little easier than that one
