temp effects on compression

[randomrider]

just a simple question... i was wondering if cold temperature will effect compression?

im just going to guess and say probably not very big numbers. probably nothing you would even notice.

i have had my shee in new york for a while cold/winter hot/summer. i never noticed a difference.

The air is denser and pistons are shriveled like a cold dick, but I don't think it would be more than a few pounds different. Jetting on the other hand is definitely affected, the colder and denser the air becomes the richer the air/fuel mixture needs to be.
