Another DRZ400 Broken Case

Sad to say that I didn't get a set of case savers install on my bike and paid the price. Dumped my bike hard on a rock and the rear break lever got pushed into the clutch cover putting a nice big hole in the cover. I If having to haul the bike 10 km out of the bush and having replace the cover and brake lever wasn't enough the clutch may be shot too. A section of what I think is called the gear assembly has a piece broken off. It would be one of the tooth looking parts that holds the plates. Even if I get it all flushed out I can't imagine it will work properly with a piece missing.

The bike went down hard enough that I can't imagine clutch covers alone preventing a crack in the case, but I guess they may have saved the clutch from damage.

I'll try to post some pic's soon as soon as I figure out how

that would be the clutch basket.ouch!sounds like when you do it,you do it right.

An ounce of prevention is worth a pound of cure !! Sorry to hear about your problem. Good Luck getting it fixed, Hope your hitting the trail ASAP !!!!

I guess in this case... you really can call it a 'break lever'. :worthy:

Here are links to pics of the damage

Does anyone know if the clutch will still function ok like this? Or should I just replace the broken clutch basket?

Can a diy'er replace a clutch or is it best I get a shop to do it?

Anyone use a different clutch cover then the oem ones? I see a few different models online. Anyone have experience with any of them. I see that Sharkfab, factory pro and one called Big Moto are on the web. Thanks for any help you can provide!!

If you put it back together like that and it comes apart you are gonna hate yourself. Get a new clutch basket and put it back together right. You can do it.

its not hard to change out the clutch basket if you get a manual or an article on how to do it, its fairly easy.

I just got a SFB Racing replacement clutch cover today. Looks fairly well built, except for that the grove that the oem o-ring gasket fits into seems deeper than the original resulting in the o-ring not touching the engine case. Seems to me that if I bolt it on like this I'll just end up with metal on metal because the o-ring does not stick out. Anyone else install a SFB clutch cover? Any suggestions? Haven't called SFB yet.


Forgot to state that this is not a new o-ring I am using. Would a new o-ring be thicker? Do they shrink?

Thanks again

O-rings don't shrink. They expand in the presence of petroleum, but if the one you've got doesn't even touch the case, I'd be wary of installing it.

I have a SBF, used the stock o-ring, no problem at all. Love it. And it's green to match my KLX.

But...they are cnc'd, not cast, so perhaps it could be slightly off?

Give them a call, I'm sure they stand behind the work they do.

"O" rings can shrink and/or swell depending on what chemicals they come in contact with. But in your case what you are seeing is "set". It has changed shape from being compressed. Measure the depth of the "O" ring groove in the OEM and the replacement cover. Depth should be the same. If it is, a new "O" ring is the answer. If not, sent the cover back.

Thanks to everyone who helped me get my bike back together. In the end the SFB cover was machined wrong. They sent me out a replacement and this one seems to fit very well. In the end I ended up with a cracked clutch pressure plate, broken hub basket, broken hub assembly on top of the clutch cover and brake lever. It was a mess. After waiting some time for all the parts to show up I think I finally got it running again. Went for a spin around the block and all seems to work well. Don't seem to see any leaks yet. Did the primary and stator fixes at the same time. These faqs plus the clutch maintenance one were a great help.

CFC Case covers are ordered and on their way. Wish I had not procrastinated on ordering them before I hit the dirt.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      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
