racingscott97 I have actually been trying to reach him at Kart Connection because he was looking for a piston from Vertex not available here since I have access to Vertex in Europe during summer. Vertex in the US won't sell you things from the European catalogue as far as I know. I actually got a 51.3 this summer for a PCR but it was expensive. Called Italy and wouldn't sell me directly, called natonal dealer for Spain and wouldn't either, told me I had to order through my local dealer there, who had no clue what I needed, so I arranged everything and got it through local dealer with 2 extra dealers making money on the way. Next time I'll try through some of my old friends back there building chassis/engines. Those crazy Europeans, lol.
