20 Most Recent 2003 Suzuki DR-Z 400 Questions & Answers

Is there. Power in bike?

K4 usually denotes 2004. This may be late 2003 onwards.

I guess in theory no it doesn't but I would be concerned that if stuff can get out then the opposite is stuff can get in. grit or grime getting in potentially could affect everything.I assuming it leaking from the counter shaft seal ? if it is recommend fixing as its only about $30 and 20 minute job why would you leave it?? Just my opinion, you could also just keep topping up with oil now and again I guess.www.motoxpartsonline.com

Saddlebags? Hein Gerike do nice ones at £49 works for me.

I have same problem have to add oil after every ride

The screw setting depends on the engine and carb condition,but you can usually start off with the screw turned out about 1 1/2 (one and one half) turns out and adjust it to obtain the best running setting from there.

If you are cleaning the carburetor, the place you need to concentrate your effort is not just the slow jet but the passageway through the carburetor body. That is usually wear the blockage is located. If you have an unusually long slow jet be sure ALL the tiny holes are clear.
You should also carefully check that the intake manifold and any gaskets between the carburetor body and the cylinder head are not cracked, separated, leaking, etc.. The extra air from a leaking connection can keep the bike from idling. Also be sure there are no cracked or leaking tubes on the outside plumbing of the carburetor.
Ethanol/alcohol style fuels lower your fuel economy and have to be taken into the carburetor through larger jets for the motorcycle to idle and run properly. you can adjust for this with bigger jets or like most people by turning up the idle. Suzuki recommends not more than 5 percent alcohol content in the fuel. If you are in an area where they are selling fuel with 10-20 percent or more, drain your fuel from the motorcycle tank and burn it in your truck. Locate a station with NO ALCOHOL fuel and see if that helps.
Poor idle can also be caused by week spark usually caused by a burnt out resister in the spark plug cap. NGK makes various styles of spark plug caps for about $5 each. Unscrew the old plug cap off the end of the wire and replace it with a new one.
Long term use of Sea Foam can eat away the interior of a motorcycle carburetor. I recommend Chevron Techron. Usually 5-10 minutes of running idle time with a shock treatment will bring many carburetors back to life with out disassembly.

PUSH AND HOLD THE TRIP SET FOR 5 SECS

there is only 1 drain plug, the oil is mostly stored in the front part of the bike and the drain is as normal at the lowers part if the engine.
the drain plug tap is found close to the front forks on the frame and is just like s normal drain opening screw top.

maybe--just go buy a clymer repair book and become a pro like us at the fix

replace it

check plug for cracked insulator. Coils? Bad fuel /fuel filter

Sounds like carby is flooding, If so remove carby dismantle / clean / reassemble. All good.

Recheck the float level, adjust if necessary.
Reblow the jets with compressed air.
If you have tampered with the air-mixture screw you will have to reset it too.
Standard setting is all the way in ...slowly as not to damage the tip, thn outwards 2 & a half turns to 3.
Hope this helps!

not 100% sure but around 20 to 40 ft.lbs

I'd check to see if it has a clutch safety switch

about 2L to 2.5L of oil and do it slowly it overfills very fast

adjust the timing a little, take off the left cover, inside the magneto is a couple of screws. you loosen these the slightly rotate the timing to ****** or advance. This should take care of your problem.

Should be a wet stator system.

i have had the same experience, try changing the spark plug lead, there may be a slight break in it causing lack of ignition
