hi i am planning on doing a air box mod to my 2005 ttr125 large wheele, i am getting a ignition pre oiled performance air filter and planning on cutting some holes in the top of the air box
#1- how big should i drill the holes and how many?
#2- i am at about 45-50 feet above sea level and i do drive on the beaches sometimes so i am at a very low level, so i was wondering what jet size i should put in for the low speed jet, and what size for the main.
#3- i am NOT putting a upgraded exhaust on the bike, other than this mod i want to do the bike is all stock.
