It seems like my bike is eating a lot of oil. Is anyone else having an issue like this? Is it a savage trait? In the last 1000 miles, The site window went from full to no oil in the window. I have no leaks. Any ideas as to what this could be? A buddy mentioned maybe the valves need adjusted. I dunno. Anyone? I used a motorcycle grade 20W-50 at the last change

Let's quantify this question.  How much is the difference between "Full to No Oil in the Window"?  That's about 1/2 quart or so isn't it?

I wouldn't be rebuilding the engine quite yet.  In 1000 miles a hot old thumper engine is gonna eat a little oil too.  

We often get used to the oil consumption in our modern, tight, temperature regulated automotive engines, and we forget that our bike is more than just a nostalgic piece of history.  It is also old technology.  If you were driving a 2007 Valverie Rune, then you could be concerned.  

Instead, just add another $2 worth of oil and happily drive another 1000 miles.  That's the way it was 1986.

Shoo away mosquitoes...I like that.  I was doing that when I started mine after the rebuild the other day.  All that engine assembly grease and oil on the valve guides and piston rings was creating a really big white cloud.  No mosquitoes in my yard

I almost forgot...It might also be good to check the oil level during a "pre-flight" inspection at least every 500 miles too.  Not quite such a long interval, just in case you really do have a problem.

Why not...but of course, if you get a 1/2 quart out of that drain we'd be best to just start a whole new topic called an "Oil Bath for My Air Filter"
