Well said, Oilcan. If people would only read their owner's manual, it would really cut down on so-called "problems". Matt, you said the temperature you were riding in was 14-15F. That is equivalent to about -9C and Honda specifically says to use 0W30 or 5W30 in this type of weather. Like Oilcan said, it's right there on page 116 of your owner's manual. I would actually use 0W30 in your situation in case it gets even colder. After winter is over, switch over to 10W40 and you'll be good to go, it's really very simple. You have to remember that your Rincon uses the same oil for the engine and tranny, so obviously it will take longer to warm up than a car's tranny, whose ATF is incredibly light weight compared to engine oil, even 0W30. If you are using the stock 10W40 oil in 15 degree weather, that is why you're having a hard time in the cold. I started my bike in -20C weather the other day, it started right up and after 4 minutes of warmup I was off. By the way, you should never start riding any ATV immediately after startup, not even a 450. 450's will drive away almost immediately but you are torturing your engine, let it warm up a few minutes. I think the Rincon cold weather startup/driveability issue is actually a non-issue. People just refuse to read the manual and take the necessary precautions to ensure proper operation. Back when I was in college, if we asked questions whose answers were readily available with a bit of reading, my old teacher would yell at us: RTFM!! You can figure out what it means. Just my opinion.
