Quote: I think it needs to be said that a radiused fillet at the edge of the journals IS A GOOD THING. It's one feature that makes aftermarket cranks BETTER THAN FACTORY CRANKSHAFTS. It would be easier and cheaper to just cut a right angle there and have a weaker journal.
Quote: many aftermarket cranks have radiused fillets which is like a small ramp between the journal and crank throw... but nobody makes narrow main bearings for the low deck motors yet. therefore it may be necessary to scrape or shave a small amount of material from the bearing
for sure it's a good thing good to point out though
