FWIW, The 5500 was offered with a 24 inch bar using .325 skip chain.  I wonder how that set up would work on your 6700?  6700 recoil, top cover (plug in air filter) and clutch cover are the same as gray 5500.  5500 has a 1mm shorter stroke over the 6700 so the cases should also be the same.  5500/6700 Bore and stroke 46x33 vs 50x34.  May be just the difference in piston height or skirt length or it may be a different crank altogether.
