of course a plug chop for each jet, at whatever temps will tell the real story
but i'm also wondering if the manual suggested jetting changes for cold weather are a little lean, as that is with the stock oil injection connected and working, which reportedly injects at 20:1 ?????
so there will be an abundance of spare oil laying in the cases at all times ???? and a constant flow of oil, no matter what jet is used
during cold weather i'd say oil is the main concern, not fuel for cooling as the cold temps will negate alot of that ????
all just thoughts to ponder ????
