I'm new to the forum and to 2 strokes but am already converted to a 2 stroke lover. I just bought a pretty nice blaster that runs pretty good aside from the clutches needing to be replaced soon. I love this thing! I only paid $250 for it so I'm sure I made out like a bandit! Only problem is I can't figure out what year the motor is. The tenth digit on the serial # is a "k". I called Yamaha and they told me the frame is an 89, but the plastics are at least 2003. It is a 6 speed. Are all blasters 6 speeds, or just after 2000? I have to order clutches and don't know the year. Pleeeaaase help!:-/
