Just a question for the tuning gurus out there!!
If my bike is currently set up perfectly and I am now fitting a ram air system, will I need to alter jetting?
I am presuming not as the Ram air does not really affect things until the speed is up, but not sure
Would you suggest altering jetting for ramair

jetting will be WAY different with a ram air box .. and it depends who's system you are fitting as to where the jetting will end up.. and wether there's a filter etc etc ..
as a rough guide,
block the air jets, R1 needles and work down from 120 ish on the mains ..
really though go and get it setup on a dyno with a big fan by somemone who's done ramaired zxr400's before.
