Default Re: Do slant heads really make a difference in power?

Compared to the stock old head, the inner combustion area of the slant head is smaller which results in higher compression. After I installed mine, I noticed the difference while starting my engine. I pedaled a few times, popped the clutch, and almost went over the handlebars, as the piston compressed fully, and the thing stumbled to life! I wasn't expecting THAT much of a compression increase!
