So I bought a 05 DRZ 125 L off craigslist and I replaced the piston, cam shaft, head, and valve cover. This is my first dirt bike because I wanted to learn how to rebuild the motor. After installing everything fallowing every direction in the owners Manuel. After I install the valve cover I would try turning the motor over with a wrench and the motor binds up. does anyone know what this could be ?

Sorry to hear about the motor binding, you are asking a very loaded question, so I'll ask you...

Cam chain tensionor not set right?

Check cam chain guides?

Cam sprocket off by 1 tooth?
