Rick LaBriola (LaBriola Machine/L.A. Suicide Jockey Shift) put this together in '89-'90. It's still crankin' out the miles. Rick got around the front pushrod angles by machining the lifter block, then he had Andrews grind a camshaft to his specs. It's 97 ci, and has dual plugged '47 heads.
Rick I've known for a long time, and I think he's one of the best machinists out there. Almost every bike I build has Rick's work in it somewhere. I've had him do some really oddball stuff for me, and he's always comes thru.
