He is a douche but his motors kick ass. He is just too cheap to hire the help he needs to get orders out in a timely manner, so him and Josh try to knock out 10+ motors a day between the two of them. Yesterday he posted a pic with 4 Franks and 8 chinagirls that they all needed to be ported and built that day. Too much work for 2 people, so orders take forever.
As for him separating ways with Zeda, he had a public argument with Zehe(CEO of JL China, who supplies the parts) way before they parted ways - complete with immature Facebook blocking and tagging, lmao. In the beginning of last year, Zehe sent him 200 cylinders and more then half of them were defective with thin and peeling chrome and visible spots in the cylinders where the aluminum showed through the chrome. He posted the private messages between the two of them spanning months trying to get it solved. They gave him the run around and basically said they are as expected, and to return any that fail or have issues AFTER running, which as a business is a terrible idea since he wanted him to sell parts that he knows are bad and only take em back when people complain. I would have ditched them way back then, but he kept ordering from them and the problems kept occuring (gas frames coming in broken, parts coming in loose and mixed up in boxes like a thrift store bin, missing orders, etc).
The final straw was the end of last year when Zehe refused to refund him for any of the defective clutches (he had 300 of them) so he has been replacing them out of his own pocket since then. I got 5 of them myself, all smoothied the bearings within the first 10-75 miles and had to spend $100 out of pocket to replace them myself. After Zehe refused to replace the clutches, their relationship got worst and Rob started calling him out publicly, and stated that he will be dropping JL China as a supplier a full MONTH before Zeda China said they were parting ways with ZedaMotorsports in an attempt to make it sound like it was their decision
. They didn't drop them, he had already publicly stated he will no longer be using them weeks before their first statement.
As of now, he is launching the billet cases with watercooled top ends and has already broken 82mph (on video with radar gun, not phone app, car speedo, or GPS)with them, and they are expected to make 15+hp once dialed in.
Again, he's not someone I would likely be friends with since he can be a douche to work with, is slow as hell to ship, and likes to talk sh*t but you can't argue that his chinagirls outperform every elses, like it or not. People like him help push the whole hobby forward, so whether you plan on ordering from him or not you should still be hoping he keeps experimenting since competition is good for everyone.
Just a perspective from a mediator. I use Zeda parts since they kick ass and are a better deal than most of the other performance vendors, not because of the owner. Most of the non-engine stuff can be had cheaper and faster ordering direct through Amazon or Ebay - its the custom stuff and the free port work on the kits that make it worth while.
