He ordered his JD and Keitech from Thumper. My question is, do these bikes set up the same? We are in the foothills of California 2400 ft elevation. Most of our riding takes place in the 2000-5000 ft range. Half the year we see 30-60 degrees and the other half is 75-100 degrees. We have stock exhaust w/ the end drilled, and the 3x3. The quote above is how Eddie had me set my DRZ up and I love it. Thanks so much!
