friend hooked up jumper cables wrong on my bike what did i blow

ya my friends a dumbass an hooked up the cables wrong on my 01 drz400s any idea what i might have blown. it was with my brand new battery too 

likely main fuse, why were you jumping a brand new battery?

Bike hasn't been starting, kept trying to start it an killed battery, hooked it up to jump cables an it started...where's the main fuse located, what the hell am I buying what's it look like an where should I go

If it started then the fuse is ok. Best thing to do is tell your friend not to touch your bike.

Main fuse is on top of the battery box under a black rubber cover.

don't know if this is a problem but throwin it out there.   Bike sits for a period unridden and the fuel evaps out of the carb. Vacuum petcock won';t let much fuel to the carb until it's running or crank a bunch of battery killing times. Then it starts. Solution, ride more often or get a petcock with a prime position or a non vacumm petcock and remember to turn gas on/off. Bike will start better.

The main fuse (only fuse) is a 20 amp standard size blade fuse located above the battery.  But a stated above, the fuse is OK if the bike starts and runs from the battery.  No reason to suspect you killed anything with the reverse jumpers.  Not good practice but mostly it just makes a lot of sparks if only momentarily connected.

Ya I found the fuse an replaced it bikes fine now besides the fact that I gotta keep the choke all the way out and jump start it to it eventually dies an I'm not able to start it again, my buddies letting me borrow his charger tomorrow so I can let my battery sit for a day think this will solve also bike only has on proem an reserve switch idk why it doesn't have off

Wish I just had a damn kick start but only electric start an I havnt been able to bump start it yet

Regarding your fuel petcock - assuming it is original - It has ON, RES and PRI. (on, reserve and prime).  OFF is automatic when the motor is not running.  It is a vacuum operated petcock.  Apparently confusing to some people but in common use on motorcycles since the late 1960's.  There needs to be a vacuum hose connected to the petcock to turn the gas on.  PRI is useful to bypass the OFF and fill the carb with fuel if the carb is for some reason dry.

Cleaning the carb would be a good idea

I cannot believe I just read that sentence.  You believe it would be easier to kick start a bike that you cannot get running with an electric starter or push starting? :jawdrop::facepalm::naughty:

I have resorted to push starting bikes after giving up on the kick start but never the other way around.


If you crank and crank you will kill the starter by overheating it and they are not cheap.  If it won't fire after about 5 rotations there is something not right and its unlikely that after 20 or 50 rotations it will suddenly start and run perfectly.  If the carb is plugged it is plugged.  Use the center petcock position 'prime' which is the same as a manual petcock 'on' if you have concerns the carb is dry but you already said it will start with choke so there is fuel in the carb.  Needing the choke is normal even in fairly warm weather but you should be able to push it in almost immediately.  If the idle circuit is plugged or the fuel screw is in too far then the idle is too lean and it will not run.  At the very least get some Seafoam fuel stabilizer and put quite a bit in the fuel.  It might help clear it out but that is only a suggestion if you are not willing to clean the carb.

Agreed with Slowriding, if you can't bump it or e start it, you SURE don't want to be trying to kick start it!

Best bet a steep hill or a slow tow.

Kicking makes teeny tiny juice to start for the effort involved. Compared to rolling wheels forcing it to turn over repeatadly. ;)

"Friend" screwed it up. Yuck yuck.

      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!
