the oil in the airbox is normal if you have not done the crank case breather reroute think of it as a cheap emmissions component. if you have the race ecm installed on your bike you can unplug that servo. if you unplug the servo with the stock ecm a check engine light will come on, but it wont hurt your bike at all having that servo unplugged ,i had mine unplug for 2 months plus the buell dealer told me it was ok to run without it that is if you have an aftermarket exhaust. you can do your own open airbox mod just do a search on the forum, and you can also do a breather reroute too.its pretty simple
