20 Most Recent 1993 Suzuki GSF 400 Bandit Questions & Answers

I suggest you check this site:http://www.sportbikez.net/There are a few answers for timing on this bike already...both ignition and valve timing.Hope this helps

If you just took the stator cover off then no, turning the motor over wont affect timing.

swop your plugs cable and see if you get spark then you know you have to replace the cables.

You only have 2 ways to go......1. fuel .....2. spark, if your cranking your bike, first off try this. crank it with no choke . if nothing happens , take your choke pull it all the way out, now crank it.
if it fires, push choke half way in, continue to crank, it should start . If nothing happens a all .

You have to pull out spark plugs, look at them closely . Is it soaked with gas ? or is it dry as a bone ? if it is soaked with gas, clean it up and dry it off, now check your gap it should be alright
but just check it anyways if the gap is to much it will not fire inside the cyclinder, if it is closed
to much it will not fire . take your plug put it back in just the plug wire and rest it up against the
head or any metal surface, now crank your bike if it has a good blue spark your good with the
electrial check both plugs same way . Now if that is ok , then you have to move on to the fuel.
if you have new clean fuel, good , if it is old like lat years get rid of it . drain everything tank and
all of your fuel filters replace, make sure all of your lines are flowing and carb will clean them self.
give it a little bit after it starts running be gentle with let everything catch up. If it needs final

adjustment on carbs take it back to who ever rebuilt them . Good Luck

This could be just about anything. Check timing and fuel supply as well as air supply.

Carb would be the place to start assuming it was running fine before it was stored. Gas can "varnish" in carbs while in storage for long periods of time if a fuel stabilizer wasn't added before storing. Might try some fuel system cleaner before going to the trouble of removing the carb.

The starter motor could be the culprit, check the starter motor.

unless you have the correct tools this is something you probably wouldn't want to get involved in as you would need a camchain splitter/riveter if you drop the old pin down the can tunnel your in a world of hurt and the only way to remove the old chain in one piece is via a complete engine rebuild also while the cams are coming out you'd want to do the valve clearances at the same time, on some models it's tappet adjustment and some it's shims which requires you having a selection of different sized shims.
My advice is give it to someone who already has the equipment and pay them it'll cost you a lot less in the end.

I am sure you can find the info you need here...good luck. Rate please if the link helps.
Thanks.

If you go to the following web site, it will give you a diagram of your coils and HT leads and a good idea of how they fit.

Sounds simple but believe me. it is nothing but a horror story if attempted. Seek out the professional for this one! Smiles!

I would disconnect the regulator so it does not charge the battery. Now... monitor the battery voltage... try starter, horn, lights, flashers... battery going down ? No fire/smoke/smells ? Re-connect regulator and check again. Regulator should charge battery @ 15volts MAX !!

i had similar problem when i took my battery off and disturbed a wire that is crutial in the circuit when running the bike with sidestand down so check you havent pulled the wires as on mine no neutral light was showing until i found i'd pulled a wire by accident

One coil works #1 and #3 cylinder and the other one works #2 and #4, it could be a bad coil or fouled plugs on the dead cylinders.

yes...

try the 600 bandit also make sure the spark isnt sparking out in head change the leeds and plugs also the coils on them get hammered by bad weather change them first i had same problem there not der new put a meter on them
