07 clutch pressure plate fit on a o5 yz450

& what causes grooves in it from the springs,I noticed springs weren't overly tight when I took them off,other than that everything else looks fine

No, the '07 pressure plate is wrong for the '06 and earlier. The '07 was made for use with one less pair of plates and with different springs.

The grooves in the spring pockets are from vibration. Nothing to worry over.

Thanks Gray,I guess I need to learn more more about the mechanical side of my bike :rolleyes:
