The rear cylinder that I tend to have problems with does have the 'safe' combo with the L barrel and H head. That's what was on it when I got the bike.
With that low compression setup, jetting it the same as the standard compression(H barrel and H head) on the front cylinder. I shouldn't have a problem with the jetting on the rear cylinder being too lean correct? Or am I completely off?
Sorry don't mean for this to be about jetting specifically. Just would like to know the general relationship between compression ratio and jetting size.

Can overly rich setup cause detonation as well?
