Just purchased the 2005 WR450F. Question? Rode for a short bit. Exhaust was glowing bright red below radiator. Checked oil. It did read half way mark. Break in hours. 10 or 20. After my first real ride I will change oil. Plan to use Yamalube 4-R 15w-50. Manual recommends gas octane of 95 or higher. Do I need that. All I see is 92/93. Where do you get 95+, I leave in Portland< Ore area. Anything else I should worry about?
