I've always thought the first few valve clearance checks are the most important. As the motor gets through it first few 10k miles or so, I would expect the adjustments to be less frequent but I too will continue to check them.
Some years ago I performed this experiment with my GL1000. Routinely I used regular gas in it. But in four separate experiments I filled it (starting with a mostly empty tank) with premium gas. In all cases - every single one - gas mileage went down by about 2 MPG. This was not what I was expecting, but it's what happened.Mikey,
You've probably heard this before, but there's no reason to use premium fuel unless you've got a higher compression engine. All the higher octane does is prevent knock. The NT won't knock with the lowest octane gas you can buiy in Coos Bay. But if you want to spend more money and feel OK with that, I don't that you'll hurt your engine. You won't get quite as good a performance from the higher octane, though.

Does anyone have any tests about anti-corrosive propertys or lubricative properties of coolant breaking down? The concentrate and the pre-mix I see on the store shelves is rated for five yearsWow... that is really something to think about. I'll have to take a look at the manufacture date of my 'new' 2010 NT and consider changing those fluids.
