so ive been researching a lot recently about the AP tuning for the YZ. almost all of the stuff ive read are for 2000ish-2004 bikes. ive got a 98 YZ400 and my FCR looks a lil different from my buddies 2000 426. so the question ive got is, which mod should i start with to adjust the AP timing/duration/volume. the bike is totally stock. but has a pretty good bog. ive ridden it like this now for about a year and kinda just ended up learning how to ride with it. when i rode my friends 426, obviously it already had been tuned cause theres no bog and its 10 times more fun to ride that way. can anyone help me out who has maybe done it on theyre older (1998-1999) YZ? thanks a bunch folks!
