I got a 2000 dyna with what I thought was a stock 88" motor with the exception of a dyna 2000 ignition and an S and S "G" carb. Now I know that a G is way too big of a carb for a stock motor so I called Cedar Valley HD in Charels City IA where the bike originally come from to see if any motor work had been done before because I bought it salvaged and have no record of anything that has been done. I was told by the tech there that a 103" kit had been put in it by the previous owner. I beleive that something has been done to it because it way more power than a stock twin cam, but I was wondering if anyone knew how to tell that something like thiis has been done without tearing the motor apart to check. If it was a screaming eagle kit I figured it would say somewhere on it but I dont know if it was S&S or screaming eagle or what.
