well i have had my 2001 savage for 8 years now and have put over 9,000 miles on it, its way past time to rejet the carb from stock. only thing i ever did was drill out the air mix screw and adjusted all the way out and still seems to run lean. i have a K&n filter on the way and am using the stock exhaust for now, with 8 holes drilled in the end of it just so it wouldn't sound like a john deer tractor lol. Hoping lancer is still selling his jet kits.
