Everyone I know that races use zenoah. All others a pos. The plating is thicker in these cheap imitator engines but yet the plating sucks. The casting at first sucked but I think they fixed that.
I mean come on the superior nickel coated piston that I bought came with this piston bearing that won't even work with the thrust washers. I had to use my zenoah piston needle bearing.
