Ok so my little brother shows up with a 95 suzuki rm 250 he traded for.he had to have one after me buying my kdx.I looked this bike over and iit has a pro circuit header annd an unknown silencer.carb needs cleaned and adjusted doesn't like to idle too well.now me and my little bro are very competitive.I've always been faster when it came to quads,cars,and our motorcycles,and atvs.but I think he may one up on me out of the box seeing how the suzi makes 51hp stock from what I read.throw a couple more on with exhaust.my question is this kdx makes 37 hp stock and I have dyno port header,pro circuit silencer,boysen reeds,uni filter no air box lid,and has been regeared what is it going to take to either beat him or atleast stay with him?I've never been out done before and don't intend to let my little bro get bragging rights that he finally beat me.so how bad ass are the suzi 250's?how well do they respond to mods?same goes for my kdx?what's it going to take or is it a lost cause?
