I installed 30W break-in oil with a ZDDP additive yesterday and proceeded to run several cycles of WOT acceleration from 30 to 65-70 in 4th gear (1:1 ratio) coasting back down to 30 with the carburetor at idle. Engine speed at 65-70 is in the 3500 rpm range (just a quick glance at the tach as watching the road pretty cloase at those speeds).
It will be a while before I have enough miles on it to know if things changed or remain the same and will report back then.
