He built my motor from the crank up and I had valves out of gap, camshaft bolt came loose and my piston is knocking. Bent my valves when cam bolt came out, he replaced one valve and it was way out.(008) on several valves. I still have a knock and this guy will not fix it. Stay as far away as possible if you want good work. He got me for 900 and I have to take it to another machine shop to fix his work.
