I'm on my second tankful with Sea Foam in my Yager. And, I've just passed 1000 miles. And, I just switched over to synthetic oil. So it could be that the engine finally loosened up. Whatever is causing it, she has a lot more power. I find that I have to be more careful starting out. The bike just wants to jump out. Not complainin, just sayin. I like it.
