Where can i get a foam air filter and a velocity stack for my 2100? I have looked at madsens but i cant seem to email them to get more info. so i really dont know if what they have advretized will work or not.
I can't help you find a velocity stack but the fella who built my race saws told me that you should aim to keep them short no longer that 1/2" flange face to the top.
Otherwise performance suffers.
That advise was offered to me by one of Australia's top Kart engine builders (now deceased ). And just when i need him most i can't find his new phone number.
ozflea..I conclude with you...keep the intake path short..the factories do a pretty darn good job of tuning this side of their engines..air filters can leave a bit to be desired though..as with the exhausts (more volume and bigger holes)
