My stock LL3 was the easiest motor i've ever had to break in. It hardly got stuck at TDC. It was also the quickest to wear out.
p.s. after trying a few different pipes, the Mugen pipe was by far the best! A little on the thirsty side though.
All I can tell you is I have had my engine apart, and there is a lot of work done to the sleeve and to the exhaust area of the case compared to a stock one....
