Hey, I have a 87 lt 250r and I put a fmf fattly and silencer on it. I run close to sea level and in hot weather. I think the jet right now is a 240. I'm not sure what jet i should go to or if i need to change other things besides the main jet. I tried talking to fmf about this but their leaving me kinda high and dry.
Thx for all your help.
