yea, so at that weight( adding more for driver) you are talking 525-550 horse motor needing that much jet. Just doesn’t sound right to me. Maybe someone else will chime in.
I am in Michigan , we get our chances in 50-60 degree air at times as well..lol
I appreciate your comments. It just seems to be what the engine likes. I will add that I don't use power valves in my 1050s and jetting has always been in the 90s.
