Another Noise Thread

Recommended Posts

Here's the problem. I just bought a 2006 DRZ 400 SM with 4300 miles. The bike runs flawlessly, but just off idle in all gears, I'm hearing a rattle or knocking sound. I hear it until the rpms get high, but I don't know if it goes away, or if the wind and other engine noise drowns it out. I've had two other DRZs, and I don't remember them having this noise. I'm no mechanic, but to me it sounds a lot like what I call piston slap. The kind of sound you get if you lug the engine in higher gears, and now I focus on the noise as soon as I start riding. Also, I don't hear it with the bike in neutral revving it in the driveway. I know it's hard to judge without hearing it yourself, but have any of you had this similar issue? I don't really want to take the bike to local Suzuki dealer because I haven't had very good experiences with their service dept. The guy I bought the bike from is a friend, and has agreed to make things right if there is a major problem. Help! I don't want to dislike this bike because of a simple problem.

i have almost 17k on my DRZ. it makes some knocking sounds here and there. occationally a new one will start then go away in about a 1000mi. these motors are noisy, i have always had clean oil come out when i change it so i dont worry about the noises anymore.

when i lug my Z i def get piston slap, i think its a common issue with these motors.

hopefully some more people chime in and can help you out!

Kind of like a chatter noise that goes off at higher revs? Notice it more from low to mid Range? Bike runs fine, even pulls top speed etc etc?

Thats what mine was like anyway. Pics are in the post (Just a little forum a few of us started to keep in touch as weve all moved over the country).

Had my whole engine rebuilt now and its as quiet as a mouse. So quiet infact i keep thinking ive stalled the engine at junctions etc etc.

You are describing the exact same noise mine makes . I took it to the dealer and said that it was piston slap , he said maybe , but would not do anything about it :lol: . His solution was to ride it and once the warranty run out they would strip it and have a look :lol: . Not mentioned , but all at my expense :banghead: . I now just rev the beejesus out of it and try not to listen to it down low , but enjoy the sweet sounds of my pipe when it is on song , greg :worthy: . [ yes I am just ignoring it , and after 2000 klms nothing has happened :busted: ]

I've had it ever since I bought the bike. Made about 5000 miles on it and it still runs great. Only thing I made is changing the cam chain, and buying MCCT. The noise is still there.

The best advice is to buy a loud pipe and forget about it. That will be the last time you hear this noise :lol: Oh and the "E" model almost doesn't make that sound...

Is it this sound? You can hear it almost all the way but particularly when he's approaching:

If yes, than it's normal :)

the sound in that video my sm makes as well. so your saying thats a normal noise? do you know why it makes the noise mine just recently started making that noise.

I would say mine makes a similar noise, Also seems to change very slightly with the temperature of the engine, more noise if it is cold or cooler. I have just been running it at higher RPM's where it seems happier anyway. Just about 1000 miles:ride: noise has not changed a bit, so i am letting go of obsessing how the engine is self destructing.

      Hey all, 
      I'm looking at buying a 2004 Suzuki DRZ400EK or at least I think it's an EK according to Vin lookup websites, but it does not appear to have a kickstarter. I was told the bike was owned by a motorcycle dealer and that it has a current green sticker, and a California license plate but has not been registered for the streets since 2011. I want this as a dual sport but am not clear if the fact that it already has a plate means I am good to register it or if maybe they took away the ability to register it after it was plated, California loves to do that kind of stuff. Since the bike was owned by a dealer I would think they were up on the latest regulations in California, but who knows. Can anyone add any insight as to what I should look for on the bike itself like the carburetor, model numbers etc? Or do I just try my luck at the DMV?

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey Guys,
      I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?
