A freind of mine went to LHT in Florida today and found out that the ctr from talking to Jhon is a garbage pulley to use on high reving motors. I guess because there is no harmonic balancer that it puts alot of stress on the oil pump and shatters. Ive seen proof of this he has 3 motors there from the cause of that pulley. I would like to hear other opnions, what you guys think. I have changed over to a oem honda crank pulley. Iam looking into Fluidampr. Iam also wanting to know what if the ctr crank pulley was balanced with the whole rotating assemblely? Would it still be worthless to use? Does the ctr in Euro/Japan use a differnt oil pump?
