[bigbuck90]

I have a 2005 z400 with a full yosi pipe with a k&n air filter with a prodesign adapter,It has a dyno jet kit in it right now but.I was wondering what jets i should be running in it for the best performance with these mods.My elivation is 4000ft to 500ft?thanks

do you have the air box lid off? the dyno jet kit comes with full instructions on what size to run and the elivation chart. i have a 155 main jet with a slip on and k&n with the air box lid off with the fuel air screw turned 3 clicks.
