DRZ400 question

Hi all, I've got a DRZ that I haven't had long, so I'm not sure if it has always done this. When I "whack" the throttle I hear a metallic clack. It is fairly loud & seems to be louder when the clutch is pulled in. Don't really know of any other problems or if this is really a problem. I don't usually jerk the throttle open when sitting at a stop but when I did the clack surprised me. Let me know what you think.

Thanks,
Murf

Piston slap, this is normal, you need to raise the idle to between 1500-1800rpm. Most bikes are setup to idle around 1200rpm from the dealer.

Thanks matty, It just makes one clack when I twist it quick then it revs and sounds normal. I'll set the idle up and ride. In normal riding I would probably never notice it.

Thank again!

Yah, if you roll on the throttle slowly you don't get the "clack", but a quick twist and "clack"!! "Clack" is actually a great word to describe the noise.
Cheers
