Hot Bike !
There is a good article in the Jan 14 edition of Hot Bike. It's called Hot Sparks. It relates mostly to ignition upgrades but also states that most riders don't give their bikes enough warm up time in cold weather. Jamie Hanson From "Speeds Performance Plus" had this to say:
"Besides barely giving that bike enough time to build up oil pressure, bad enough on a late model EFI bike. "That get up and go is pretty much a guarantee for fouled plugs, black as coal!" "The computer is still in its warm up mode." "It's like riding off with the choke full on."
Commuting 25 miles one would think the oil could reach normal or close to normal temp. At least 200 degrees by the time you get to 10 miles or so. I never rode a bike in 30 degree weather though so I cant help with a suggestion other than trying a longer warm up time. Let's say 10 min. Blocking the oil cooler is a good idea. Out of curiosity what are you measuring the oil temp with?
