My motor bought around the same time as Jay(Serpent720) is still running strong.
I have three gallons through it. Raced the KO and bumped up twice in the mains. Raced the Toys For Tots and bumped up twice in the mains again.
I replaced the rod at or before the gallon is finished and I am on my third rod. The motor still has tons of compression. I am able to practically run one plug for an entire gallon. My only reason to switch plugs was only during the A-main when I switched it for a new one just to be safe.
The break-in process was effortless to begin with and was like that everytime I replaced the rod. I've never had such a fast motor that is so easy to run and maintain. I can't say the same for my experience with Nova motors. I will definitely get another Picco for my next engine.
