Greg is a top engineer boys he's been in the business for a long time, I first meet him in the 90's when iwas racing jetski's, he's got all the trick CNC gear at shop and it's a family  affair with him and  his two boys. And he does play with early CR bushes aswell, I think Chippo had some work done there.
