I have looked closely. And I have pointed that ring out to the Said Sayer of the phrase above, in person nonetheless. It was simply denounced with the "internally balanced" arguement. Well, I may ONLY be a junior in engineering at the famed University of Illinois, but I still know for sure that parts dont have strips of rubber in them for nothing. And I know for a fact that after a lot of miles, an engine is no longer internally balanced. This is called "wear". lol

There WILL be a resonance frequency (some RPM, will be different for all motors) at which the crankshaft WILL experience major vibration, no matter how well some computer supposedly balanced the motor.

For financial reasons (yes, I really am THAT poor, plus its 100 bucks for 1 hp!!!) and for crankshaft safekeeping, as of today I have jumped on the "dont get a udp" bandwagon. Hell, we can use my wagon as a bandwagon if you guys want.

Said Sayer of the phrase above, let's not let this get between us ok? "its your engine its your decision" leave it at that.
