I am new at this site and i have an 07 trx 450er with a trinity full ext., a k&n air filter, a plenum, procom cdi box, jet kit, and a hotter plug. my buddy has a suzuki 450 with a full yoshi, a programmer , 1 tooth lower front sprocket, and a cherry bomb. most of the time, if i dont stand it up i get hem all the way to 5th then he comes back and gets me by about 1 length. what can i do to get him all the time start to finish? i thought about a stage 2 cam and port the head. i just dont want to lose any reliability.
