Good to hear, another Suzuki rider
I think we have exactly the same model and year DRZ, i bought mine new in 2004 in the same colours as yours.
Together with a friend we made a mold of a rally fairing, so we can reproduce these fairings from fiberglass and sell them if people are interested.
The tank is a Aqualine safari 17Ltr tank, the cams and exhaust are from Yoshimura and i installed a Keihin FCR carb.
I use it for amateur rally`s and for offroad holiday`s, last year i went to Sweden with a couple of friends, it was great!
Thanks again for your comments on the BMW
