drz400 engine

  1. Tech/Setups for Supermoto
    I picked up a 2002 Drz400s the other day with a newly installed 470 kit, and FCR 41mm carb. The bike is currently running rich, bike accelerates pretty well with occasional stumble, however when maintaining a constant speed at about 25% throttle say 25mph it will stumble and run rough. It's not...
  2. Wanted
    I am looking for a good top head assy or maybe even a whole engine if the price is right. Let me know what you have and how much.
