Hmm, cranks to hard or too soft? can anybody give a hardness rating to look for? As if I could do something about it! LOL... I have seen sirrio cranks break down the middle of the outer clutch brg. area, on a SG shaft engine, leaving theouer end of the crank. Just like the material was too hard. Top Gun since you say the cranks were too soft, what hardnest scale are you using? Thanks!
