I have a 99 200 with fmf torque pipe and silencer,low to mid reeds,10 ounce fly wheel weight,if it looks like I like low end your right,need it to ride the tight trails in the rain forest of Oregon.I'm thinking about porting it and would like to if any one out there has had it done,I'm sure there are,can you tell me what to expect?I wouldn't mind a little more on top but don't want to lose any on the bottom,hopefully gain all around ?
