Only "old" carburators had issues with more/less oxygen.
There might be a difference for our CB 1100 between hot and cold weather: maybe under very hot conditions the air cooling is at its limit and the fuel tends to more spontaneous combustions in the "overheated" cylinders. Just guessing...
I'll bet that's why Honda recommends 86 Octane. The compression is pretty low but being air cooled and lean due to emissions, summer heat may push it towards pre-ignition.
Ok, sure, but what if you're using full-synthetic oil instead of regular mineral oil?
