k so the other day my buddy gave me cp ported cylinders, still on the stock bore. im sending the cylinders to herr or fast to get bored and such. my bike now just has fmf exhaust, +4 timing and open airbox wtih a KN. i ride only trails. my question is, should i get new reeds while im redoing it, if so what kind, and will they work in my stock reed cage. also, can anyone give me a ball park answer on what i should jet this to for break in>?
