I just bought an '06 DRZ400S...paid $3700, has only 345 miles on it. the guy hadn't rode it (or registered it ) since Septemper 06. This all sounds good, so far, i'm sure...here's the problem: I choke it, start it and it runs, sitting. when i try to take off the choke, it kills. also, when i ride it (while choked) it'll cut out.

My guess is that sitting for over 2 years "something" has gone to crap. I put all new gas in it, but am thinking it is a "carb" issue, but am clueless.

Anyone can suggest a fix for my new toy?

Your pilot jet is clogged. Buy a new one instead of trying to clean it out. You could just go ahead & do the 3X3 airbox mod & install a jet kit.

Yes, classic symptoms of this. But if you have carb cleaner soaker and compressed air, no need to buy a new one - they usually clean up good as new.

Exactly. Just this Saturday I cleaned the crap out of my pilot jet when my DRZ displayed the same symptoms. I used some Seafoam and compressed air and it is as good as new.

Maybe we need our own thread.

It wasn't really TDC, then, was it?

If the head gasket is bad, it could be letting either oil or combustion gases into the cooling system. If the latter, you might hear some air coming out of the coolant return line when you compress the cylinder. Motors overheat quickly with hot exhaust gases entering the cooling system.
You might also smell antifreeze in the exhaust or see a little steam (which looks like white smoke).

That or the water pump isn't working (or not working very well) would be my best guesses.

Good luck, sounds like a nightmare so far.

I'm a new proud owner of a DRZ 400s. Just bought it yeasterday and I can already tell I made a wise choice. It's a barely used 2008 without any mods.
tomorrow I'm changing out all the fluids and this weekend I'll take it out camping.
My camping choices for theis weekend, Sawtooths, Idaho, Idaho desert, or YellowStone. I guess I'll let everyone what I chose when I get back Tuesday.
I should have bought a DRZ years ago.

Welcome to the brotherhood Mick! Ditch the "Deathwings" and enjoy the ride.

As I replied earlier, a larger sport windscreen caused my bike to be blown around a lot on the interstate. Wind and passing vehicles made the bike wobble. I rode 1300+ miles of secondary roads in 3 days with this windscreen, and it worked OK for me. FYI.

Thanks for the close-ups! Does it wiggle at hiway speeds or do the zipties hold pretty good?

It is stable at speed. The zip ties have held it since I owned it (over 11k miles and 3 years so far). I am surprised it it hasn't fallen off, actually.

If you're designing one from scratch, a better mounting method is probably a good idea.

Brown truck arrived yesterday with the new GoPro wide angle .

Got home with a little bit of light left in the day to make a short test video along a small section of the trails by the house.

Hope you enjoy. http://www.vimeo.com/4758221

Very nice hak! The video was surprisingly steady. Enjoy!
