For the price and quality, this piston is awesome. This Namura company obviously prides themselves on their quality of products.This was an easy install, and it's fitment was perfect for my old cylinder. I thought I was going to need to replace my cylinder head after pulling my old piston and finding all of the carbon burns on the inside of the cylinder housing. I was able to clean everything off and make it look brand new. After installing this piston, my compression was back in spec. I will definitely be buying more products from them in the future if this piston holds out.
