My younger brother has a 2003 crf 150 with BBR exhaust Rev Box and air filter. It has good power but needs some more. has anyone treid BBR's big bore kit? If you have does the bike run hot, do they make an oil cooler for the bike, and are there any other mods that are needed with the big bore. :cry:
