I have a older guy with a 00 ITR that is a customer at the dealership that I work at asking me about Unorthodox crank pulley if is going to hurt his motor. I told him the factory one has a harmonic balancer built into the pulley and that is why it is so heavy. I told him Im not 100% sure cuz I have never check into them so Im not sure. I know if there is not a harmonic balancer on the motor, you will trash the bearings.
So the question is, does the Unorthodox pulley have a balancer in it? Does anyone have them on their ITR?
Thanks

 

no harmonic dampener if i remember right, but search, as there is a whole lot of threads on this. its too tough to tell though, because some people have torn down motors with them on and seen no excessive wear, others have seen tons. the jury is out and will probably never be decided i think you can buy one with a dampener from endyne though,

 

I run the whole set on my R with no problems. Budman runs them too; he recommended them to me. The answer is NO. It does NOT have a balancer on it. Honestly, if I were to do it all over again I would've skipped the pulleys.
