Reviewed in the United States on October 30, 2016
Had these in for about a year or so now and they are holding strong. Originally had to replace stock pistons due to scarring of the cylinders due to poor maintenance from previous owner. Should have gone over but didn't have the money for proper boring. So I honed it out and am getting a bit of blowby. Even with blowby these things definitely hold their own!
