Rim Lock / Bead Lock / Bead Stopper Installation - If the bulk of your
Suzuki Dual Sport riding takes place in the dirt, then it's very likely that
you've made the switch from the stock "semi-knob" tires to genuine, full knobbies
(DOT-approved, of course, if you still ride on the pavement at all).
But did you also install a rim lock? |

Suzuki DRZ400E Advanced Jetting - The DRZ400E and the DRZ400E/Kick
come standard with a Keihin FCR 39 flatside carburetor. It comes from Suzuki
jetted pretty lean though, and needs to be rejetted. First
thing you need to do is open up the airbox. Take off your seat and
pull the airbox restrictor. By Matt Nelson |
Suzuki DRZ400S Upgrades -
The Suzuki DRZ400S is currently the
best dual purpose bike on the market. Stock I would say the
DRZ400S is suited for 75% dirt, 25% street. My goal was to
make it 95% dirt, 5% street. Fortunately, Suzuki has made
this conversion fairly simple. I said simple, not
cheap. By Matt Nelson |
