Customer Reviews
I rarely leave a review but this one was real bad. This piston didn’t have the screwdriver groove in it to help install the wrist pin clips. Beta uses one sided wrist pin clips—there’s no special tool. A groove for a screwdriver should be on there and is in the picture of the product. We messed with it for over 2 hours and ended up putting the old piston back in with new rings after cleaning it up real nice. We never even got one clip in and scratched up the piston in the process. Maybe they sent the wrong piston?? Don’t buy.
