racer
yes, its a fact he will want to go faster. and it will save him time and money to do it the 1st time. he does need seat time and some common sense, 150 shot is very safe on just about any engine with no problems (just read and foliow the mfg directions) so it will be there when he wants it. i think i would be more concerned with the cast crank and the 10 bolt rear......just saying.
