    I got my wife a high comp head from gas bikes and I wanted to know because my wife keeps asking me, does a high comp head make an engine leaner?

    I wouldn't think so, but it will make your engine possibly ping or 4 stroke more on regular gas. You may need to move up to pure premium gas with this change in compression ratio.
