Oops. I think my comment on "increased power" wasn't clear. What I meant by that is having an ignition box with higher spark output so a guy can increase his spark plug gap to somewhere around .060".

And I agree, there's no sense in reving the snot out of these Hinckley twins, especially without port work/bigger intake valves. That's why I like the idea of a stoker crank: more torque and power without the revs.
