Always a grey area on the new motors. USA spec is a tight .10mm IN / .15mm EX - Euro Spec is .15/.20mm - if you like them quieter, I would go with .125mm IN / .175mm EX.
.15/.20 is a world spec, per updated bulletin. See third post above.Todd - is .10 and .15mm correct? The service manual states .15 and .20mm. I adjusted to .15 and .20 and still seemed rather noisy to me, A friend of mine with a Stelvio and Griso says .10/.15mm is correct for the 4 valve motors. So, I re-adjusted to the tighter settings. Please set me straight, here. Thanks.
