Re: qd 10 oil ratio

[Leon]

QD-10’s are best at 24:1 or heavier. The wrist pins is the only reason I would go 16:1. The big rod ends and mains are all needle bearings, but the small rod ends were still a weak spot. The guys typically would change out the rod and piston sets from the later models, to get the better rod ends with needle bearings.
