Hey, guys just picked up a 2001 Drz 250 for a killer deal. I have some basic questions about the bike. Does anyone know of a free shop manual for this bike online? If I can find one, I won't need any of these questions answered. First, what oil does this bike take? 10W40?? and how much. Second, I've never had a bike with an oil cooler before, are their any additional steps during oil change? such as draining the oil radiator? Any tips for setting tappets? Thanks in advance!
