just wondering what the comp ratio on a 2006 summit 800 adrenaline is. my shop manual says 12.0 +- .5:1 and i'm inclined to believe that. it just doesn't differentiate between adrenaline and x models.
what makes me wonder is i talked to a fellow about it and he seemed pretty sure it was 13.5:1 and another guy said it was 13:1.
regardless of what number other ppl are saying, they all seem to think that the 2006 has a higher comp ratio than previous revs.
any truth to this?
i have a straightline head with 12.8:1 compression, so it just makes me wonder if i am in fact running a lower comp ratio with the aftermarket head.
