Default Engine Noise with 62cc

I just finished a build, its a cranny with a 62cc dax motor, my questin is that this motor as well as other motors that i see around town that are less than 67cc seem to make a lot of engine noise, sounds like the bearings rattling but run very well, my oil mix is amsoil somewhere between 32 and 40:1, the reason i say somewhere is due to i already had some gas mixed at 50:1 for my other motorized bicycle so i added some oil to the tank and shook it, its not to much oil, any one know why these little engines make more noise??? I hope all that makes sense...
