I think this motor may be too new for many race parts to start floating around. I know that tractor pulling sources have not advertised any parts for these, but since these are vertical shaft engines then they may not mess with it. There have been some associations change rules to allow them, but still no word on performance parts. A person might be able to adapt existing parts for these engines, but still becareful of the plastic/nylon gears. Sorry not much help.
