no air box
 

thinking of ditching the airbox ..

i've seen a few of you out there with filters on instead .. any recommendations?

is there a downside?

Think I'm going to have a do with this too - or maybe just the top of the air box so I can still house the K and N. Took the trumpets out for the last two races and the bike was dragging in more air - induction.

lid off as a minimum!! With high liuft s,tage 2 filter of some form

Think most of the front guys have junked their airbox and use pod filters and none so far seem to have what I was worried about; water in wet races affected it. Think many will have fitted some form of deflector to the front of the frame so you dont get direct flow in one pot and disturbed air in the other



see skids, I was listening ;) :lol:

ooooooooo .. direct flow and disturbed air !!! wassall that about then?

anyone tried a ram air type system?

was half considering just having open inlets

one trumpet points forward, one up, so airflow isnt consistent....I think :puzzled:

IMHO: There is only likely to be one 'gain' in junking the complete airbox and that is the weight saving. You are extremely unlikely to make any performance gains sticking filters in the end of the inlets. Most 'Classic Racers' dream of still air boxes/plenum chambers. Get it built properly and a 620 will do 65bhp with the air box (lid cut open and foam filtering place) fitted!

mine made nearly 64 with it on, just open lid and good filter. Only reason I wanted to was makes access easier and wanted to fit different tank

Ditto, if memory serves about 1.6kgs :D

at the moment its lid off with no filter.

i didn't expect to get any extra horsies .. just want to lose the weight and gain some space

definately take the lid off .. makes a big difference
