DR650 trouble free jetting?

[Jeffr726]

Hi everyone, I'm a new owner of a 2007 DR650 and have logged just over 1000miles on it. Next summer I'm heading South to Argentina. I took the advice of many others in the Suzuki thread and contacted Jesse at Kientech and am expecting new springs, a fuel/air screw, along with a dynojet kit. (just a bit of a plug for Jesse- he was by far the most pleasant and knowledgeable person I have ever done business with) Jesse recommended putting the dynojet 155 main in, along with drilling the carb, and opening the top of the box. I'm going to stick with the stock exhaust. I'd like to know what riders on this site, who have taken the trips that have brought them from sea level to 10,000+ feet have done? From what I've read elsewhere, the dynojet mods seem to lead to a nightmare of low mileage followed by endless jet and needle configuration changes. I'm content with how my stock DR650 runs at sea level. (sometimes ignorance is a good thing) Could the altitude changes be managed and the performance I get now maintained, by gradually opening up more and more of the air box and adjusting the fuel/air screw while leaving everything else stock? Sorry for the long post, but I wanted to make the question as specific as I could at this time. I know jetting has been discussed countless times over, but what I've read seems to focus more on peak performance, rather than good performance over the widest range of elevations.
