I spent a year learning how to wrench and completely rebuilding the bike between my trips so major current modifications include the IMS 4 gal tank, Corbin seat, and Britannia Composites front fairing. On top of that I’ve modified the jetting, camshafts, airbox, added a kickstart, renthal bars, 3 finger levers, tank filter, HD clutch springs, case savers, braided front brake lines. and swapped my rear cylinder to a honda CRF, petcock to yamaha raptor, and reg-rec to SH775 mosfet. I tried getting a Lectron carburetor even – but could never get it to work right so went back to the stock Mikuni. Some of these mods are definitely recommended for overlanding, others were just upgrading as I replaced worn or broken parts. It’s a fair bit of work to adventurize a DRZ properly, but it does pay off.
