First post and new to the forums. I've been riding about 9 years have owned many different bikes and am super excited to be the proud owner of this A1 zx12r. My plan is to preserve the bike as is and to ride it! I've already changed the coolant and synced the throttle bodies next up I'm going to perform a valve adjustment and plug change since the bike has 18k miles. The bike has mods but I'm not sure what kind.
