Erik Brigham = True Performance Engineering and the 2 new cylinder setups about to hit the market at a great price.
Erik has been porting motors for myself, the Rad Dudes and the racing community for years, trust me when I say he is OLD AS THE HILLS... JK, he has been in the industry for many years, you can tell by his constant references to the "550 and Scott Watson"
This setup will drop right onto any 701/760 based bottom end with some clearancing of cases needed for the 95mm pistons to drop in. Everything will be a straight bolt in from a current Yami setup.
Basically you can trash your stock top end, get Erik to port your cases and drop this bad boy on top to run 940cc (I think exact numbers are 946cc, Erik can chime in)... with stock stroke reliability...
