WarNerve Posted September 28, 2005 On my 05 DRZ400s the bike wont quit reving after I let off the throttle. When i give it gas in neutral and let off the throttle it revs for a second than returns to idle, its not a high rev but the rev slows to an idle just for a second. Any idea whats wrong?? sorry for the confusing explanation Share this post Link to post Share on other sites
Noble Posted September 28, 2005 Yes. This is quite common. Idle mixture is lean. You need to un-seal the idle mixture scew and turn it out some. This will help, may even fix it completely. If not, next step is a larger pilot jet. You have a 22.5. The next size up is a 25 and seems to work well for most people. Share this post Link to post Share on other sites
