i'll have to think about it, plus i'd want pics and listing of any damage.
rear oil pickup? exactly what are you referring to? you referring to something to help out with internal lubrication because some bikes experience a lack of proper lubricaiton when they are wheelied a lot? if that's what you're referring to, then it pretty much depends on how much, how long, and how high you wheelie the bike. the more of any of those 3, the more i'd look into it, but only if you know that others have seized their engines on that particular model due to excessive wheelies.
