Hi friend. What is this cam? I bought trx450er 07(08). When I bought I saw trx was with full exhaust system, HRC CDI RPM Sub and airboxcover, intake snorkel. It seemed to me that the engine is very good mid range, but lacks top-end power. I make out the top of the engine and pulled the camshaftand measure it. Help to understand this standard cam from trx450 or crf450 or HRC? sorry for my english.
