Takin from our motorcycle history
Coop, me bro, you are right on target with the eBay special scenario. You have been in this motorcycle engine game longer than most and you should remember the discrepancy in performance that existed in the "stock" motor classes when we were racing bikes. The expensive engine builders buy a boat load of parts and find the ones that offer an advantage. Such as the lightest and/or longest pin to pin rods, pistons, piston pins, camshafts, gears and clutch assemblies. They then take every tolerance to the max according to the manual or their interpretation of it. Damn the longevity of the engine, it will haul ass. All of the machine work done to each and every component to eek out that last bit of performance adds up to the total package when done. I did not consider these to be "as run in the bike" stock motors then and don't consider it now, but that is the game. Not that I am sour about it, but I did get beat for the WERA 750 Stock championship by a Smokin Joe's Honda(DuHammel's) and a Yoshimura Suzuki(Russel's) at Road Atlanta a life time ago. Passed'm in the corners and got blown off the track down the straights. Just trying to make a point that racers will exploit rules for an advantage no matter what the consequences and I still feel that JR's punishment does not fit the crime.
