out of gas

Ok coming home form work on my 05 DRZ400SM and she dies. I knew she was out of gas so I flipped the switch to res and it doesn't start. I turn it to prime and it starts and runs for 10 seconds and dies. Well I am two miles from the nearest gas station so I push her all the way. I get some gas in her and she fires up. Well I am confused to high heavens because where was the reserve? I mean is there a way to run the reserve in with the rest of the gas somehow? Possible I might of been in reserve already. So can you run the whole tank on that and go right through all the gas?

Help me PLEASE.


Well sure, if you leave it on reserve you will run a full tank down to dry.

If you leave it in reserve through the whole tank of gas, the yes, you can definately run out of gas. How many miles when you ran out? Do you use your trip meter? I reset mine @ every fillup just in case I forget & leave it in reserve (done it a couple of times!). I know @ or around the 100 mile mark, I should have to switch to reserve.

Another possibility, however unlikely, is that your petcock is clogged on the reserve side. Might be worth a look. Good luck!!!

Well I am two miles from the nearest gas station so I push her all the way.Help me PLEASE.


You poor fool :lame:

Sorry I had a good :p:p:lame: at that, done it myself :bonk:

All you had to do is lay the bike down on the left side, to let the trapped fuel get to the tap and you could have ridden it.

And yes if you leave the tap on res, it will empty the tank :p



My brother the ass used to leave the bikes on reserve and not tell me. Ever had to push a 500+ lb KZ up hill to the gas station? Be thankful the DRZ is so light! Oh ya he couldn't sit right till my foot was removed from his ass. Though I think that was the last time he did it....

You could try an aftermarket tank. With the Clarke you always know how much fuel you have. Then it really is your fault...... :excuseme:

This may sound silly but look at the petcock in the light to find the arrow. When I first got my bike I assumed the lever indicated the selected position (reserve or run) of the valve like my other bikes.

My Clarke has set me free!! I went 100 miles on fire roads and trails today and never once had to add miles up in my head to see if I could make it back to a gas station. I did the same thing yesterday. I love it!

I Bought the bike from the dealer only three weeks ago they put on hot cams the dynojet stage 1 jet kit as welll as the Yoshimura RS-3 complete exhaust. So I had a thought they could of screwed something up or it was already on res. The tank only took 2.4 gallons to fill up to the rim and later I fould out it was leaking somehwere from underneigh. :bonk: Well we live and we hopefully learn but it was fun coasting down some hills on the sidewalk without my helmet waiting for a cop to pull me over. :excuseme:

Thanks for the responses much appriciated.


I'm just irritated that both my bikes are different. On the DRZ you turn the petcock backwards for reserve and on my streetbike you flip it forward for reserve. The other thing is that it requires a lot more effort to turn, add to that, that with a single carb it gives you very little lead time that you are running dry. Nothing worse than sitting at a redlight and having your engine die as you take off. Anymore I flip to reserve if I'm in a city and know I'll be getting gas soon.

About how many miles can an "E" go on reserve?

About how many miles can an "E" go on reserve?

i can't say how many miles the reserve is good for as it depends on how many mpg you're getting.

i do know the total fuel capacity of a stock e model tank is 2.6 gallons, and has 0.6 gallon reserve.

you should be good for 25 miles i would think.

Well I have run out twice, First time I had it on prime. I was sure to tell my friend who advisd me that was not a good idea. Runs the tank completely dry.

Ran out again and I primed it than ran it on reserve. Kinda tough getting it started, worried me I'd be calling the wife again.

120 to empty on prime, 100 to empty on ON, don't know how far reserve will get you.

120 to empty on prime, 100 to empty on ON, don't know how far reserve will get you.

That would be 20 miles on reserve then :ride::ride:

I sure do love my Yellow Clarke tank - lots of range and I always know what my fuel status is.

For the money, it's one of the best things you can do to your DRZ.

After running out and having to call the wife in the middle of the night, I'm not going to ASSUME anything.

If you notice you are running out of gas (e.g., sputtering, bucking) before the engine dies, you only need to turn the switch to Reserve and it will keep running. If the engine does die then stop the bike safely and turn the switch to Prime for a few seconds (to refill the carb bowl by gravity), then turn it to Reserve and restart. Do NOT leave it on Prime (or the engine will flood and die again). Follow this procedure and it will work as advertised (it has for me). And you won't have to call for help if you can find a gas station within the next 25+ miles (the reserve)!

P.S. I believe California bikes have slightly less reserve (0.4 vs 0.6). You don't want to fill a CA tank to the brim or the gas can overflow into the vent and/or foul the smog cannister (causing starting problems). (This happens sometimes when you drop the bike--even if you don't overfill the tank--ugh!)

I run in "run" and around 80 miles I KNOW it's gunna start sputtering. When it does, I can flip to reserve on the fly and head to the nearest gas station. I consider reserve OUT OF GAS! This has not left me stranded and pushing as of yet. :ride:

After running out and having to call the wife in the middle of the night, I'm not going to ASSUME anything.

I get your point, but it is not an assumption, just simple maths.

How did the wife feel about having to rescue you, can't have been to bad, she came and got you :ride::ride:

I trust reserve on my S for 15 miles, but no more.

And remember, laying the bike down on it's left side will get the rest of the fuel to the tap, in my case that gave me another 6 miles without problems.

Enough to get to the fuel station.



05 DRZ 400SM 100mi. on main, 134.5 mi. and your pushing. :ride:

      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!
      This post has been promoted to a wiki
      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!
