i usually do about 8-10 tanks before its 100% raced tuned, i dont believe it 100% breaking in an engine before race tune. 100% broken in is usually 1-2 Gallons, hell on my btt it was 3 gallons, most engines get 8-10 before performance starts to drop, rather then mess with it ill buy a new engine. i have a ninja right now with about 15 gallons on it, never even opened it up and it still has good compression, will idle all day long.

but enough of that, Bonito is 100% raced tuned now, top end is amazing, hard to tell the bottom due to i was on asphalt but it seems good with a weak clutch. if i need to ill go all alum but i think this is going to be a good engine. Ill know more after this weekend
