Great up-grade
I put this big bore kit on my bike , and wow everything fit excellent and it was so easy. I got so much more power now when i'm up in the mountains and over on the track. It was well worth the money and it was so quick to change out. I'm satisfied and happy with my choice.

Great power increase in my WR450. The C-clips for the piston wrist pin are a bit difficult. I think the design would need a lock ring...All over good choice. Recommend rejetting your carb and a quick shot excellerator pump cover for best performance.
