Hey guys, a few weeks ago we picked up an 06 YZ450F (Yellow too..hehe) Its got about 60 miles on it (I dont know how many hours...we never really counted that) Its still got the original oil in it. How soon should I change it, and what should I use? Also, I heard from someone that these new ones use two oils, one for the tranny, like the CRF's do...is this true? I know this is probably posted somewhere else but I cant find it. Is there anything I should know about this bike? Within a few weeks its gonna be skidplated, get a kickstand and spark arrestor (PromotoBillet) and a few other things.... Any advice?
