Lighten up your DR-Z400S


Want to make your DR-Z400S lighter for the dirt but still have a street legal dual sport?

The first 8 to 10 pounds are pretty easy to lose: Just remove stuff. These are real weights:

- Passenger foot pegs: 1 lb. 10 oz. / pair

- Stock mirrors: 1 lb. each

- Chain guard: 8 oz.

- Helmet lock, not including tab on frame: 6 oz.

- Tool kit and fender bag: 1 lb. 14 oz.

- Handlebar weights: 1 lb. / pair

- Front reflectors and bracket: 6 oz.

- Front turn signals: 13 oz. / pair

- Big ugly stock tail light and blinkers: 2 lbs. 12 oz.

( -11 lbs saved, but add back a tail light and mirror, and turn signals if your state requires them )


Some northern riders lose the fan: -14 oz.

Replacing the stock metal tank with the same size plastic- no weight savings. Adding a larger tank and filling it up can easily add 10 pounds.


Biggest bang for the buck mod?

- Stock battery: 5 lbs. 13 oz.

+ Shorai Lithium Iron: 1 lb. 8 oz. # LFX14A2-BS12 ( -4 1/4 lbs saved )



Common accessories: (Please fill in the missing numbers if you know them)

- Stock muffler: 9 lbs. + 2 lbs. for header pipe

+ FMF Q4: 5 lbs. 8 oz. + 2 lbs. for PowerBomb header

+ Yoshimura RS-2: 9 lbs. 2 oz.

+ MRD/SSW: 8 lbs.


- Stock headlight: 3 lbs. 8 oz.

+ Acerbis Cyclops: 1 lb. 10 oz.


- Stock tail light assembly: 2 lbs. 12 oz.

+ DRC Edge: 8 oz. + turn signals if needed ( -2 1/4 lbs saved )


- Stock turn signals: 1 1/2 lbs. for all 4

+ LED turn signals: less than half that, depends on what brand you choose


- Stock speedo: ?

+ TrailTech Vapor: ?


Common add ons:

+ Radiator guards- Unibiker: 1 lb. 8 oz.

+ Hand guards- Acerbis Rally Pro: 1 lb. 12 oz.

+ Skid plate- Hyde plastic: Same weight as the 3 stock pieces you'll remove

+ ProMoto Billet Rack- 1 lb. 12 oz.


And remember that lighter is always better for dirt but heavier is a lot better for 70+ on the highway.

User Feedback


really the plastic gas thank (e model) doesn't give any improvements in weight?

i was going to buy one :(


i bought the bike 10 days ago and removed quite a bit,

i did pretty much all of the above,

now waiting on this danmoto muffler they claim 2.5 kilos it's like 6lbs 2oz.


but i thought the plastic thank would give me at list 6/8 lbs, did you weight both?

Ebp- I didn't personally weight both but many have posted in other DRZ threads that they had and there was no weight saving with the plastic tank.  The metal in the tank is very thin, it doesn't weigh as much as you think.  Remove it and weigh it empty, it's pretty light.


If you do weigh both please post it here, I'll update the Wiki to show true weights.

      Hi All,
      I was just given a red Suzuki "quadmaster" 50.  This is the 2 stroke oil injected quad with red plastics.  I have a couple of questions that I am hoping for some help with:
      1. Any advice on where to find the VIN #?  I would like to figure out what year it is so that I can properly order parts. The only numbers I have located are on the engine at the base of the cylinder on the pull-start side.
      2. What is everyone's actual experience with Chinese-made carbs and top end kits?  The reviews on Amazon and Ebay are either "total garbage" or "best thing ever". I don't know what to think.
      3. This quad has a ton of hours on it, but it does run ok.  The carb seems pretty tired, and leaks fuel like crazy.  I have not torn into it yet to see what the float condition is.  I'd love to hear folks experience with carb rebuilds again vs. aftermarket replacement.  I am also not seeing a lot of piston's available.  RMATV does not seem to even list an OEM option from what I can tell.  Is there a best option for top end freshening?
      Thanks for any advice or help.  I'm trying to keep this "free" quad as cheap as possible while trying to get it to run well for my kids.

      I wanna install a SuperMoto conversion kit on my 07 DRZ400s, and from what I see most people suggest the bare bones kit from motostrano. But this one here is a couple hundred bucks cheaper but is there anything essential missing here?
      Warp 9 supermoto front wheel 3.50X17″ rim with tire
      Oversized 320mm rotor with caliper adapter bracket
      Warp 9 supermoto rear wheel 4.25 or 5.0X17″ rim with tire
      Rotor and sprocket

      Hey All!
      I recently traded a bike for my new 1973 Suzuki ts400. The bike has been sitting awhile, after doing the normal, carb gaskets cleaning, checking spark, then realizing the ignition system (pei) needs a timing light to check timing, i tried to start it up with a little bit of premixed gas just to see where its at... the only thing i get get the ol girl to do its backfire out of the carb (no elbow or airbox) it seems like its got hell of a compression to it but i removed the exhaust to take a peek at the rings. It seemed to be scored up, so i took some pics. Anyone know what the compression is supposed to be? Any help is greatly appreciated! 
      Thanks, Austin.

      I've decided to attempt the mid-body gasket replacement on my vintage 2000 slant FCR carb, stock on the DRZ 400 E. If you are like me you have scoured the forums for info on doing this service but found maybe 2 or 3 pictures of a taken apart FCR, dead end threads, and tons of negativity. 
      BUT! Is it really that difficult of a repair to perform correctly? Well I have had my carb on and off at least a dozen times, trying different jets, cleaning, etc. For the last 3 years I've been getting by with the coast enrichener circuit bypassed to at least get enough fuel in the idle circuit to run ok. But it just wasn't working anymore. I could clean the carb out and get it to run for a little while, but after sitting it wouldn't start again. I tried ordering a refurb FCR-MX over a week ago and the guy has gone MIA and nothing shipped. I ordered from I would advise avoiding... But will update if I hear back and he has a decent reason for the delay. Anyways, it made me seriously look into the "unserviceable" midbody gasket. I mean, you can buy the gasket here:
      So today I ripped the carb apart again, but this time to the very last fastener, separating the carb bodies. I even found my smoking gun, in the one picture with the hoop thingy removed you can see the gasket has expanded and spilled into a passageway. This passageway leads directly to the pilot jet, blocking it's flow. Though as you can see every rubber piece inside is completely trashed. Which makes sense, do you really expect these gaskets to last 20 years? Or in this case 18? If you have taken apart your FCR and went, wow that fuel bowl gasket is recked yo! I need a new one! Well you can bet your mid-body gasket looks the same. Really I see no reason I couldn't get this sealed back up with a new gasket and some fuel-proof RTV to replace the epoxy seal around the edge. Why wouldn't it work? Just doesn't make sense to me all the negativity you find toward this repair.... But I haven't finished yet so who knows if it will actually work on the bike. But I think it'll run like new when I'm done. I hope it works out for me and I can inspire some others who would otherwise be forced to buy an 800 dollar carb to do this repair instead.
      Wish me luck!
