2006 jetting

[One_Bad_400]

what is the stock 450r jetting (livin in the mid-south / mississippi)... if i go ahead and put a full system on my bike how much larger of a jet do you think i should go

[Colby@C&DRacing]

If you are going to mod the air box lid the best jetting setup for the 450r is the HRC jet kit

if u put a cheap uni filter,, remove the air box lid,, and put a full system on--- in between a 172 , 175, 178,, depending on pump or race fuel

What about adding a cam to the equation w/airbox mod & exhaust? (sorry to hijack thread :) )
