Anyone out there gone out and readjusted their Testa engine to the new 0.002 / 0.005 valve clearances?
I found pretty poor base-circle roundness on both the opener cam lobes and the closer cam lobes on my 2005 999S. I started measuring the gap at only 1 point, being at 180 degrees from the lobe apex. Just before buttoning things up I decided to spin a cam with the feeler gauge in place..... Whoa!! BIG surprize there!! I found as much as 0.002 difference either way at various points around the circle.Yep, it will expand, but .002 usually gives some binding, especially if you're not perfect on the openers. It makes the whole process much more difficult to find that .002 and get it right. I've built motors with .002/.004 before, but its very time consuming.
