I have to agree, everyone mods there engines different and Rick is no exception, I have been running his mods for quite some time now and have not had any problems, I get my engines from JP France and they go to rick to be modded. The problem with people doing there own mods is each brand of engine needs something different, whether it be a timing change on the crank or sleeve, lightened crank, or just the ports need cleaning. So just making improvements to the sleeve and crank doesn't mean you are getting the full effects of the mod you have done. Anybody can make fixtures for a sleeve and mass produce 100 motors in a week, but I would rather have my engines hand modded to ensure quality. If you want a specific mod from Rick just ask. His motors are done on the conservative side, you want more power just tell him you want the max power from the engine or try a drag mod in a buggy.
