Brought 04 DR650 a week ago and power was very very flat not disapointing though just not inspiring.
Done some modes Very Very happy! (I am comparying to my modified XR600).
I did different modes to what I have seen on Thumper.com Although using info as guide.
Type into google : jetting Mikuni BST40 (there will be special xmas edition PDF although for KTM640,same carb,same jetting,makes you wonder about DR wont match LC4!) great guide.
If no good email me and i will send PDF, and pictures of my mods.
