i have a kx 250 2 stroke everything new fmf exhaust, v force, new top end and cleaned everything for the exhaust valve but it still doesnt have the power that i expected what is wrong
Damn, look at Jackson getting all mechanical here. When you say "still doesnt have the power that i expected" What does that mean? I'm guessing the bike ran great and then something happened and you made all these changes?What year is the bike? Is this stock bore? When you say new FMF exhaust, are talking pipe or silencer or both? Have you cleaned the carb? What is the current jetting? Have you re jetted for the pipe and reeds? Sorry but give us as much history and info as you can so we can help you.
By the way welcome to the forum and post some pic of it and what to you ride trail or track?
