Re: Race Crank Balance
The pro teams order lot's of them at once (because of long lead time) in bob-weight steps of about 20 grams.
They rarely balance them beyond that.
Still never heard of a good reason for overbalance.

Re: Race Crank Balance
Or, to put it as a %, if the bobweight is 1500 grams then 20/1500=0.0133 or 1.3% so they can get within +/- 0.67%.SchmidtMotorWorks wrote: ↑Fri Dec 07, 2018 7:27 pmThe pro teams order lot's of them at once (because of long lead time) in bob-weight steps of about 20 grams.

Re: Race Crank Balance
But, in crankshaft engine balancing that opinion is normally based upon RPM range to be run;
not whether it is to be designated "Race" or not.
