I have a 2002 kx250 that I have stripped apart(getting frame powdercoated.anyways i want to make this bike a bit better for next year.I have about $1600 to spend now and will save a bit more before spring.what would be the best mods for power/handling that i could buy with this budget?.I want a bit more power and a bit stiffer suspention for big jumps(I am 200lbs).any ways the bike is a 2002 kx250 with a pc platinum pipe, pc silencer,boysen reeds,aero tapper bars,renthal grips,twin air filter.I also have all the after market plastics/grafics so i don't want to spend any more on those.the bike has low hours but I think i should get a top end rebuild soon.I might switch the reeds with a rad valve would this be a good move?thanx for any help
