hey guys. im new to this forum, im also very new to atvs. so bear with me. i just picked up a suzuki eiger 400 2003 (automatic) with some issues that im not affraid to fix and make look bran new. i mainly picked it up to help with hunting for the main part. anyways these are the list of issues and the solutions i think i found. please let me know if im on the right track here.


- headlights dont work
-when it runs it smells like its pumping to much fuel
-air box and air filter are filthy
- parking break doesn't work


solutions (i think)

- fixed headlights (brass conductor wasnt flush against the other brass to turn on headlights)
-pumping out to much fuel not enough air intake/ petcock no off option. solution ( buy yamaha raptor 660 petcock switch out with the stock one i have, this will let me connect the air valves as well, as of right now the air valves are plugged, this is because of the petcock i have now and to much fuel that is being sucked into the air valve like a vacuum resulting in some fuel in airbox, this is what im thinking as the valves are plugged right now for the air.
- buy new air filter clean out airbox.
- the parking break will be another project after i get it running again.

any help or input really is appreciated!

 

*update*

woke up today went int he garage and the airbox had some fuel in it. i re moved all the panels, removed the air box. the next thing im going to do is take apart the carb and see if everything is okay in there as well. im going to need to drain the tank and the oil as well it looks like. should i drain from the petcock or drain from he fill tube?

another update*

i ordered a new petcock a new air filter and a fuel filter. im going to install these and see if she runs better before i take the carb apart.

 

If you are lucky, you may get away with cleaning the insides of the ignition switch, but they usually start playing up again before long.

I don't like fitting on/off taps to Suzukis, with this type, you must remember to turn the tap off after you stop the engine, every time, or you risk filling the airbox with fuel. With a working, genuine tap, on run, you don't get problems as a rule.

If the footbrake works OK, but the rear handbrake doesn't, the cable is sticking, and should be replaced. However, the rear brake problem is almost always the pivot in the backplate seized. On the Eiger it is the O ring. The alloy corrodes round the lever side O ring and squeezes it tight round the shaft. The recess for the O ring must be cleaned out properly, any rust on pin removed, and the assembly greased before re-assembly.

 

much appreciated! i looks like the foot break works as suppose to but the front right handbreak looks like it also isnt working at the moment ill try and see if i can figure that out. i found an online manual for this quad so thats helping quit a bit also ive been in the process of draining the gas tank at the moment. i dont havve enough gas cans at the moment tho hahah

 

ok. airbox is removed, all panels are removed, gas tank has been drained , battery is out. going to pick up some Suzuki SAE 10W-40 tomorrow, drain the oil and put some new oil in.

the Yamaha petcock also comes in tomorrow so ill be installing that tomorrow,

question, theres another tube thats leading to the back towards my airbox and seat. is this the vent tube? if so where is it suppose to connect to? there is a little hole on my airbox that it looks like it can hook up to as well. sorry for the really noob questions.

one last thing!, my air filter does not come in until next week, is it okay if i start my atv up without a airfilter in the airbox just to see how things are going? it was blowing a little black smoke the other day when reving it which means that its burning to rich. when i opened the airbox the air filter was disgusting so im thinking that might also be why. just wondering if i can start it up with no filter on it just to see how she is.

thanks guys i know im a super noob LOL

 

There are so many vent tubes I can't remember what goes where. You can test run the bike without filter, Usually when it has filled the airbox with fuel the filter is soaked in it, and won't run with the filter on. I squeeze as much as possible out, then, once the engine has run for a bit, put it back on, the engine runs rich for a while but will clear once the fuel has been sucked through. You will need to blank the vacuum tube off or it will suck air into the manifold through it.

 

awesome. still waiting for canada post to bring my petcock. fathers bringing a new oil filter and some fresh oil home as well so the oil change will most likely happen today. so with this new petcock i just need to plug the vacumm hose to the carb right? although i think it already is blocked with a screw.

 

another update.

ive cleaned the air box fully, my fuel filter and petcock come in tomorrow, and the air filter will come in next week,

picked up a new oil filter, im wondering what oil to get. ive been reading SAE motorcycle oil 5W-30 ? is this correct? i went to Canadian tire and they didnt have any. i will be using it in the winter. also synthetic? semi synthetic?

 

We use semi synthetic 10w-40 in everything, never had problems, it must be "suitable for motorcycles" as you have a "wet" centrifugal clutch in the engine.

 

got it. drained the oil today but crapy tire gave me the wrong oil filter, ordered one from amazon should be here tomorrow morning. also amazon prime sucks petcock comes tomorrow was suppose to be here 2 days ago.
