What size tank? Suggestions?

I would appreciate some input into what gas tank I should go with for my 07 DRZ400SM.

A few things first though.

I would like a range of 200km(160ml) or better without a huge jump in discomfort if at all.

Painting suggestions.( For best quality, all the aftermarket are plastic )

Quality-fit and finish

I plan on an aftermarket seat so fit is important.

With that said I also have some engine mods-gasket, cams, carb, 3x3 and full exaust. With these mods and the stock tank I get about 130km before reserve. So all in all about 140km before I'm done. between 30-35miles to the gallon or 60-70km gallon.

I'm also thinking of going to big bore kit( 440 athena most likely ) in the future. So I would like to compensate for this possibility.

I've thought of changing the gearing, but only if and when I go to the big bore.

Thanks for the input. I know it's a lot to consider but thanks the same.

your not asking for a huge range, i dont have the IMS, i have the clarke, but my friend got IMS for his 650, and his is much better quality, look more into the IMS 3.2 gallon, ask someone about it who owns one. my clarke 3.9 gets about 280KM a tank before reserve.

Well, simple math would suggest if you get 130 km out of 2 gal and you want to get at least 200 km before reserve, you need a 3.7 gal tank (= 2.0 gal X 200/130 + 0.6 gal reserve).

You must do a lot of high speed riding because 65 km per gal seems on the low side. A stock 'SM' easily gets 95 km or more per gal.

Clarke 3.9 is great! Mine holds 4.1 actual. Quality is good too.

Yeah but he's running an FCR not a BSR36 CV.Still on mine I average 45mpg.

He needs a bigger tank but I'm not convinced by his criteria that he would be happy with a Clarke 3.9 like I am.You can't move too far forward on a Clarke 3.9 like you can on the stock tank and it complicates the design and installation of an aftermarket seat.The IMS 3.2 or 4.0 might make more sense or perhaps custom fitting the Acerbis 4.25 E model tank to allow him more range.

i have the 17 litre safari tank on order , i have done a lot of research into the product . the only problems are with the petcocks seizing up .

they are good value at $ 449.00 aud for the 17 litre .

They say only the first ones seize. I think it's not a problem anymore.


I've got the 28l one and it seems that I can go to the end of the world with one full tank. After 300km still has plenty gas left in it. My only rant about it is that it doesn't come in blue and that white one looks fugly. I wonder... they don't sell the blue DRZ in Australia???

I've been very happy with the Clarke. Mine is a big bore stroker with 41mm FCR carb. The only bad thing I can think of on the Clarke is it necessitates modifying the choke because of the FCR carb. Basically the choke will not fully open but there are easy solutions to the problem e.g. cut 1/2 inch off choke shaft, drill hole and put in key ring.

I wonder... they don't sell the blue DRZ in Australia???

They do but everyone over here buy's the E model as they are registerable nationwide (and everyone wants to go fast over here so blue is out :thumbsup: )

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      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!
