Is this the right drain bolt? I'm at my first oil change on my new '05 450. The manual (page 3-23) lists the 6 different drain bolts you need to remove. I can easily find all of them except for #3 "Drain Bolt (with gasket)". Am I correct in assuming this is the bolt on frame (right above where the stock glide plate ends)? It is painted blue and looks like the diagram but I wanted to check. Do any of you have a pattern of when you change the oil? (every ride? after a certain amoun of miles?) Do you change the filter each time?
