I just Bought 2005 drz supermoto with yoshi tri oval. Been running just 87 octane will i gain with 93 octane. Plus how would it run with race fuel.2005_0422Image0004.JPG [/img]

Unless you change the base gasket, piston, etc. you will not gain anything by running a higher octane IMHO. Stick with the 87 / 88 octane and your bike will run better.

I just use the pump gas, 93 octane...... I am pretty sure. It works great. From what I heard it is better for the bike, plus I get a little better gas mileage.

I just paid $431.89 cents to fill my S tank today....she gets 87 octane and likes it.

:naughty: Wow I know gas prices were out of control in CA,,, but not that bad :naughty: Or did you install that new IMS 150 gal Cross Country, Team tank :D


The best pump gas here is 91 octane. I mix it 80/20 with VP 110. VP 110 is actually fairly reasonable now that pump prices have gone thru the freakin roof. Getting lots more use outta the DRZ and the cold weather gear now and the truck stays at home.

:D :D :naughty:

Okay, so it was only $11.00 - but it was $11.00 :cry:

Can't wait to go fill up my Ram next week.

Wow, why do your octane ratings fluctuate so wildly? We have two octanes - 95 and 98. 98 is almost never used - most cars and bikes go OK on 95, as does my DRZ.


California gets oxygenated crappy-ass 87, 89 and 92.

      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!
