2004 450 yzf

What is the best tune up for this bike guys ? Oil type, spark plug, air filter , aftermarket exhaust, and suspension setting for a 235 lb rider? Any secrets to get more power or make it run nicer? Thanks alot

This is a WR forum but questions like this are exactly what stickys are made for. Go though 'em then ask from there. Most of the tuning info already in there should transfer over to the YZF.


Check your valve clearances before you do much riding at all! You don't want your new bike costing you ton's of dough just because you were too lazy to do a little maintenance. Maniac
