My thoughts on DR650 jetting in a nutshell: The DJ needle 3 from the top, 155 main jet, air-fuel screw, and air-box cut as per jesse's instructions, will get you to 99.9% of the places on your trip. In other words, you will not have to pull over on the side of the road and change your jetting just to get to where you want to go on a daily basis.

For example, in Peru I went from 13,000+ to sea level in a couple hours with that setting.

With the DJ needle clip fourth from the top, I couldn't even go from sea-level to 5000ft, without pulling over on the side of the road to lean it out.

At sea-level, having the needle fourth from the top does run better, and the stock jetting runs better at 10,000+, but if you're constantly changing elevations, the clip 3 down and the 155 will work well. I'm not saying this is the only way, but it's what worked for me, and it kept things simple. I'm lazy, and although it is easy to change, I didn't want to do it daily, weekly, or even monthly, just to get a couple more hp at a given elevation.

If you're setting off on a RTW you have plenty of time to learn as you go as to what works for you. Jet and needle changes take 15 to 20 minutes on a DR, so I wouldn't worry about it too much, and it sounds like you already have the DJ kit to give you options. Change it as often as you please/feel necessary.

I'm obviously a little partial, but you went with a great bike! I don't know how many times I heard other bikers say they had gone with a DR650 as well.

Cheers,
Jeff
