I have a suzuki rm 125 I bought it with a gold series fmf pipe on it. It seems to me that its running way rich cause when I stick my finger in the end of the pipe its like raw fuel almost its like carbon really bad. Plug is like a real golden brown. But it is really dawgy like not alot of bottom end and it wont rev high either. So I am woundering if it needs to be rejetted because the pipe was put on there. If anyone could tell me what jets need to be in there with that pipe I would really appreciate it..
