Well I was drag racing yesterday and I used to beat my friend's YFZ450 before his cam mod. He has full exhaust and k & N. Now with his cam mod I still take him but untill 5th gear when he very slowly starts creeping on me. I was thinking of swaping my 36t for a 34t or would adding a 15t front be a better idea instead. Is a 15ft and 36t combo overkill? Thanks.
