Bryons 30% with 11% oil for first gallon. Engine is still pretty tight, ~1/3gallon through it.
Tuning HSN first, long WOT runs on pavement. Once the top end runs "clean" I've leaned it out another hour or two.

I seem to always struggle tuning a Novarossi. All my other OS engines, Samaurai, FX tune with ease and run strong all day. I can never get my Novarossi to come back in to a nice steady idle for 10secs then drop like my other engines. If I do get to that point I get a lean bog on the low end once the engine warms up nice and hot at the track.
I tune only when the engine is hot, and chassis is saturated... I feel like there is a different method to tuning a Novarossi.. Or maybe they just don't return to a idle as nice as other engines....
