Arrived quickly and safely. Great price too. I actually haven't installed it yet, but it looks very well made and I like the coated skirts. I bought a 71mm jug kit for a Timberwolf that came with a dished piston. I am using this flat top to get the correct 9.5 to 1 that my TTR has, and increasing displacement from 225 to 230 (really 223cc to 229cc if you want to be technical) this should work well thank you
