First off thanks for stopping by, I'm new to the motorcross scene (or any dirt bike scene) and hope you can help me some. I just picked up a 2004 KX250, bike starts right up and runs great. Tilt the bike over some today to look at ol through the glass and seemed thick and grey? Also anyone who's running this bike what oil are you using for the engine and for transmission? I wanna change them and keep a eye, read some and seems water seals leak and get into oil but doesn't look milky. The clutch seems notchy, when letting off the clutch it will kinda jump. Any help will be great!
