Thanks everybody for all the help on this[sm=thumbup.gif].
I do have a lot of experience with automotive racing engines and I don't want you to think I am a total maroon . I was taught that engine stresses increase at the square to RPM so I was thinking that if I could keep my revs low enough , that cheap .61 I bought would give me a decent amount of service life before becoming a paperweight. I am still coming to terms with an engine turning 15,000 RPM without doing a grenade imitation[:@]. All that with an unsupported crankpin is just awesome and todays engines are really a marvel to me.
