Bike wobbles above 60

When I get up above 60mph on the highway the bike wobbles back and forth, not up and down. Gets worse when a truck goes by and blows me around. It wobbles in the steering but not consistent only during bumps or traffic wind. Has anyone had this problem? Any Ideas?

I would just make sure everything, I mean everything is tight. I think it's natural depending on the wind and the conditions to wobble. It's just a 300 lb machine and a slight wind or a big truck could make it wobble.... But I would check everything:excuseme:

Believe it or not, the problem is most likely you. When you are hitting bumps and being blown around by the wind you are putting inputs into the bar that are making the bike wobble. This is common, and is why road racers are very sure to ride "loose" and put most of their weight on the tank. Not so easy to do on a dual sport or dirt bike.

You should be able to decrease the wobble by trying not to be so stiff on the bike, dont hold on to the bars with a death grip. Relax your arms and you should get less wobble.

Hope this helps. It always has helped me.

I had the same issue. Acerbis SM front fender worked for me... :ride:

First... I would check the head bearings. If they check out... then what the guys above said holds. People who have death grip on the bars normally cause wobble.

If you have rimlocks, are they counterbalanced?

You guys got me thinkin. It has a touring windshield that may be catchin the wind! I just installed it for winter riding.

Check that your tire pressure is correct.

What bike do you have, s, e, k, sm? What tires? Stock, knobby, sm?

The bike does get blown around a bit, but I ride the freeway at 70mph+ every day and it's not really too bad. I did have some instability when I was running the D606 knobbies, but now I have a second set of wheels with the trailwings and it's much better.

Like the other said check the bike over and loosen up it makes a big difference. Some of my friends had the same problem and they were fighting the bike.

I put new tyres on and a dampner on my DRZ made a big diference

Wheel bearings

Stearing head bearings

Swing arm bearings

Tire pressure


How you're riding it

Suspension condition and settings...

Check those and get back to us.

I had the same problem with my 2007 S model, these are the things I did:

1, lubricate and check suspension torques, use the manual and torque items in specified order!

2, ensure proper spring rate front and rear for your weight to ensure weight distributed properly (I upped mine using eibach and racetech parts/215lbs, 4gal IMS tank)

3, check tire pressure (I run ~23psi w/stock tires)

4, ensure wheels balanced consider having a dealer do this as well as true the wheels or build a jig and have a spare weekend to play with it and tape on/clamp on wheel weights. I used "Ride On" puncture preventer, (commonly called slime) which also help to balance the wheel in motion, not sure how well this works

5, SM type front fender

6, added Scotts steering dampner (most of my troubles were corrected before this)

7, dont squeeze the crap out of the bars

keep in mind the bike has a pretty steep rake angle, after all its a dirt bike you can ride on the street and not originally intended for high speed open road riding. You'll note the SM model has a different front end configuration... Good luck.

i had the same issue for a bout 2 weeks.

as i relaxed on the bike its gone away.

it was a death grip. an not letting the bike roll on bumps... be free-er and all will be well

has anyone seen Speedway GP? the fast guys just rest on the bike and let it drive around even pastrana rides loose, and he is no slouch

Interestingly, when you do get the death wobbles the easy way out of it is to accelerate..

Mine gets a bad wobble at about 85 mph, I wish I could power through it but at that speed your almost at the end of your top end. I tried taking the mirrors off and no luck, I have had my springs redone for my weight and it still does it. I don't grip it (death grip) the only other thing is the front finder. I took it back to the dealer and they re-balanced the front tire.

I put new tyres on and a dampner on my DRZ made a big diference

me too...

I fought a bad wobble for a while. I checked every bolt on the bike and took the rims off and reinstalled but it was still there. I just replaced my rear tire yesterday and the wobble went away. I couldn't do above 60.

You mean they aren't supposed to do that?

I was having wobble at around 55 mph. I recently replaced my front wheel and it went away completely

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks

      I did the fix last night and took some pics and notes to make this easy on people that haven't done it and want more detail. Please chime in if you think I've missed something.
      Required Tools:
      Set of Allen wrenches
      #3 Phillips screwdriver
      small flat head screwdriver
      8 & 10 mm sockets
      13 mm open end wrench (I needed this to remove my skid plate)
      snap ring pliers
      gasket scraper
      compressed air
      Required Parts:
      New clutch cover gasket, Suzuki Part # 11482-29F00
      Tube or can of RTV sealant
      Oil filter and oil (if you plan to change the oil)
      1. Remove your skid plate (if you have one). I have a Tonn's skid plate and it was in the way.
      2. Remove right side radiator cover.
      3. Unbolt the rear brake lever. This will require removing a cotter pin on the backside of the bolt, and then the bolt itself. I was able to swing the lever far enough out of the way without completely removing it from the bike (see pic).

      4. Drain the coolant. This requires removing the radiator cap and the small bolt on the water pump, which has an aluminum washer on it. I rocked the bike from side to side to get most of the coolant out of the bike.
      5. The oil, two options here. You can either drain the oil and remove the oil filter or you can do what I did which is lay the bike on its left side to keep the oil from pouring out of the engine when you remove the clutch cover. I still removed the oil filter so I could clean the clutch cover with brake clean after scraping the old gasket off.
      6. Loosen the hose clamp on the coolant hose that attaches to the top of the water pump and fold the hose out of the way.
      7. Remove the water pump cover and the clutch cover by removing the bolts holding them on. Note that some of the bolts are of different sizes so keep track of which hole you pulled them from. Also, not all of the bolts need be removed, see the pic below.

      8. Remove the old gasket from the clutch cover and/or the engine with your gasket scraper. I then cleaned the clutch cover with brake cleaner as it was fairly oily.
      9. With your snap ring pliers, remove the snap ring from the plastic gear on the clutch cover seen here:

      10. Remove the plastic gear.
      11. Push out the metal pin and remove the washer underneath as seen here:

      12. With a screwdriver or whatever your preferred tool, remove the “E” clip as seen here:

      13. After removing the “E” clip push the water pump shaft out of the clutch cover.
      14. You will now have the part in your hand that needs fixing. Remove the porcelain gasket at the bottom of the shaft by blowing it with compressed air. Don’t not pry it with a screwdriver as it could damage the gasket. Mine was stuck fairly well so I sprayed some WD-40 on first to loosen it up.
      15. If you used WD-40 clean the shaft and gasket with some brake cleaner and then apply the RTV sealant to this area (I reused this pic as its perfect):

      16. Push the gasket back down flush on the shaft wiping away any excess RTV that may flow out.
      17. Reassemble the shaft into the clutch cover in reverse order as listed in steps 9-13.
      18. Place your new clutch cover gasket on the engine and then place the cover back onto the bike.
      19. Put the bolts back into the clutch and water pump cover and tighten equally. I could not find a torque setting for these in the manual so I snugged them evenly.
      20. Put the oil filter or a new one in the bike and put the oil filter cover back on.
      21. Re-attach the brake lever and tighten the bolt to 21 ft lbs. Be sure to install a new cotter pin on the backside of the bolt.
      22. If you drained your oil, refill the crankcase with the proper amount. If you didn’t drain the oil be sure you have enough in the crankcase from oil lost from removing the clutch cover.
      23. Let bike sit for 24 hours to let the RTV set up before adding coolant.
      24. Re-attach the coolant hose to the top of the water pump and tighten the hose clamp.
      25. Fill the radiator with a “Silicate Free” anti-freeze and put the radiator cap back on and tighten the radiator cap screw.
      26. Put the radiator cover and your skid plate back on the bike.
      27. You are done, go ride!

      Since I've been getting a few requests a week to e-mail the re-jet instructions word document (offered to send it to someone in old post that lives on) I thought I'd throw this post together. It is perhaps the one stop shop for 3x3 mod info: the master 3x3 post
      The 3x3 Mod
      So what is the 3x3 mod anyway? Well, this mod is basically re-jetting your carb and allowing it to run to its full potential. This mod can be done by even the most newbie of wrenchers out there. 3x3 refers to the size of hole that you will need to cut into the top of your airbox where your snorkel currently is. Don’t worry, you are not carelessly risking getting water into your engine by removing the snorkel. The bread and butter of the mod is the taper of new needle which you will get with your kit.
      Jet kits can be found through the TT here
      Scroll down to the bottom to find the right kit for your DRZ
      If you purchased a S kit for SM by accident don’t worry it will work (different jetting specs are used, just ask!)
      There are some great instructions outlining the procedure and here are two:
      bayoubikebruiser’s post is a nice one (Good Job BBB)
      Note that BBB followed the TPS sensor wire back and detached from the clip it there rather than removing the TPS off the carb.
      Another read is the attached word file (which i convereted to pdf and can be found here for your convenience) which has ‘been around the block’ to say the least.
      Sample Jetting recommendations (note: these are different for different elevations and different bikes)
      - 150 main jet (155mj for full exhaust system)
      - 25 pilot jet
      - 2nd clip on needle from top
      - 2.5 turns out on fuel screw
      - 140 – 142.mj (bigger for exhaust)
      - 25 pilot jet
      - 4th position from top
      - 2.5 to 3 turns out on fuel screw
      Burned’s fuel screw setting method:
      with the bike warm and idleing turn the fuel screw in till the idle drops/misses.then go back out till the idle peaks/smooths.
      this should happen between 1 and 3 turns out.
      if you end up at less than 1 turn you need a smaller pilot jet.more than 2.5 (or 3 turns on a cv) you need a bigger pilot jet.
      choose the appropriate size and retest.
      The 25 Pilot jet part number for TT is:
      So… now you have the info that you need, get to it! Your bike will sound better and rip a little faster; get ready to grin!
