so ive got a 2005 yz125 that im tryin to get some more horses outta to keep up with these 250 four and two strokes this season. the first option i stumbled upon was the 144 kit. i have never bored any of my bikes (and have never blown a single bike up nor had any problems with any of my bikes) so i honestly dont know how reliable this process is. any input on it? my second option is porting and polishing it, putting a v force 3 reed cage in it and changing the gearing on it. how much would that help me? ive already got a fmf sst with a titanium 2 silencer on it. im just trying to get a little more power outta my little 125 to keep up a little more instead of spending 6 grand on a ktm150 or buy a 250 2 stroke that will ride me more than i will ride it. any input on this would help me out alot!
