I own a 2001 YZ-250F. The bike does have a PC pipe and header and 2 teeth larger on the rear sproket. I rode an 04 YZ-250F with the exaxt same mods and while I loved how light the 04 felt I could not help notice how much more torque and low end my bike has. What did they change in 04 to make it so 2 stroke like? If I buy an 04 can I make it like mine by adding more flywheel or changing cams? I race mx but like the torque of the 01. This is my first post.
