I saw the first few pages of this thread and figured they were okay. My fault for not reading further.
Anyway, my experience: Ordered a motor and carb with extras from them to replace a busted Wildcat. Took over a week for them to ship it. Emails were met with radio silence. When it finally arrived, packaging was almost nonexistent; everything was thrown in the box willy-nilly with nary a scrap of bubble wrap or newspaper to be found. Luckily, the only casualty was a bent idle screw on the carb; everything else seems to have survived the ordeal and there were no missing parts, which, considering the swiss-cheese-like nature of the box when it arrived, is nothing short of a miracle. Aside from that, the product itself looks to be okay; the motor appears to have no serious QA issues and rotates freely. Even though I ordered the "performance" motor with the billet cylinder head, the standard head was also included. Fodder for the spares box, I guess. The velocity stack also seems to be of decent quality.
From what I can tell, it only went this well due to sheer luck and could have gone much worse. Not recommended. Normally I'd give them the benefit of the doubt over the shipping time, due to the pandemic and all, but the lack of communication and godawful packing job are inexcusable. Also, a funny note: The shipping policy on their website says they don't ship to California, which I thought explained why it hadn't shipped, but they went ahead and sent it anyway.
