compression ratio increase?
After looking at the harley web page and seeing the stock compression ratio for the sportsters being only about 8.9:1 I have to ask, has anyone milled the heads and increased that ratio to something like 11.0:1 or more?
I simply ask because from my point of view, that 8.9:1 is a low figure, and some pretty nice gains could be had simply from bumping that number up a few notches.
so, has anyone ever done something like this?
