Thanks for all of your input. And yeah, the engine really stays cool for the first 10 minutes. I was kind of worried about how cold it was. Yesterday I finished the break-in, leaned it, tuned it, tuned the low-speed, and retuned the high speed. Idle is at 2100 and completely smooth. 1800 was a little rough, so i upped the rpm's a bit. It peaks with the 15x4W at 9700, enriched to 9400.
