Please send reply directly to me at above address. Just purchased a 72 350 motor in a 76 400 frame. I understand this is supposed to be a very potent cycle, better handling than the S2, but what about the weight? 353 for the s2, do you feel the Hybrid would be much or any more? Also, I am looking for a set of USED chambers for this bike. Thanks, George in Tallahassee
