i just recently bought my first dirt bike about 3 weeks ago a 2001 cr125. ( i finally switched from quads) its a great bike, still gotta get used to the 2 stroke engine. i was wondering if anyone knew how much oil exactly to put in the crankcase. i have the oil, but i dont know how much to put in. also, is there a dipstick somewhere on this bike, if not how do u know how much oil is in there? one more question, right where the head pipe comes off the engine head, theres always oil right there. is that normal? thanks
