20 Most Recent 2005 Suzuki GS 500 F Questions & Answers

Question edited to add maker. Question moved to category. Surging is normally because of air leaks in the inlet manifold, too much air.

Have you tried driving it next to a block wall? The echo off of the wall is great for narrowing down strange sounds..

Did you measure how much came out? That would be a good amount to start with, then check the level, top up if neccessary until it reads right on the dipstick.

The basics first. Check that the battery is charged, fuses are ok to include the ignition solenoid fuse. Should be a 30A. (Usually near the battery) Next starter button tests ok, then check starter solenoid. Hope this helps

To much air not enough air or the fuel

jets probly need ajust--getta clymer manual -if u dont do it rite ull ruin the engine--a pro shud really doit---------also is the batt holding 12.6v-spark cud be weak

this bike is very finiky about its plugs if there not up to it the bike will play up a new set will tell if it was the plugs or the carb may need tweeking up,

Lean mixtures burn very slowly, at times slowly enough to continue burning through the power and exhaust stroke, causing a backfire when the intake valve opens, and that flame gets a shot at the new mixture charge.

In normal operation, as the engine slows, the fuel delivery from the main circuit falls off, and the idle circuit is supposed to take over. If the idle circuit flows insufficiently, that becomes a transition to fuel starvation.

You can try pointing an unlit propane torch into the inlet air, and see if you can get closer to an idle while supplying a supplementary fuel source. You will need to do this in a way that gets propane to both carburetor inlets, maybe rigging a Y with vacuum hoses and electrical tape...

This started with work on the carburetors, so the fuel system would be the most suspect. That, and the fact that it will run at higher RPM would seem to rule out fuel delivery.

I was looking around at photos while developing this answer (needed to know whether this was a twin or a 4-cylinder), and one resource said the idle speed should be 1,200. I don't know if that's right, but maybe 1,000 RPM is too slow for this motor to keep it together. (I do doubt that, though.)

When I wrote that last sentence, I started to second guess myself, thinking "What if the fuel shutoff(s) is/are vacuum operated, and as the bike approaches idle there is insufficient vacuum to hold it/them open?" But the I rejected that, because there is even less vacuum at cranking speeds, yet the bike starts.

sounds like fuel problem. Check fuel filter and lines

Sounds like the spark wires are dried out and cracked and losing the spark to ground. Start the bike in the dark and spray some water on the plug wires, you should see some nice blue sparks jumping around, even without spraying the water maybe.

Check the spark rubber hood for leak. Or the plug hood is not fitted properly in one of the plugs. check any insulation damage in the plug wire.

may be stuck choke or clogged air filter. If unsure consult dealer. Sudden cut out at speed is a risk.

Speed of the GS 500 F is 115 MPH but I had my bike up to 200 KPH and still had room on the tach thats 124 MPH not bad for a 16 year old design

Hi, the starter is located on the top side of the engine just under the carburetors under a cover secured by 2 bolts, the startor clutch is within the left engine case, firstly i would check you have sufficuant power in your battery, also that it is not in gear, the bikes prop stand is in the uprite position and you have pulled in the clutch lever all the way to the handlebar before yoe make any attempts to replace the starter motor. Also locate the starter solenoide this is the magnetic switch used for connecting the battery live to the started motor, this is the thick wire at the plus side of the battery after a short wire it will connect to the solenoide lift up the covers from over the 2wires ang momentarily bridge them together using a pair insulated pliers this should then turn the starter, if it does then the problem is elsewere as you are directly powering the starter, WARNING you should always remove the battery leads when removing the starter to avoide accidental short circuits

You only need to remove the caliper. There is usually a bolt/pin holding the pads in. Not knowing the year and model, i can not give specific instructions.

its fuel related.eather staarving for fuel or getting to much air.check floats.simply tap on the bottom or side of carb some times that frees the float.hopes this helps

Sounds good or just adjust it so it has 1/4 inch of freeplay at the end of the handle. If the cable adjuster seems be be turned all the way in then theirs a screw and locknut adjuster where the cable connects on the engine end. with the lock nut loose turn the screw out for more freeplay and in for less. Make sure you tighten this locknut as it'll cause you all kinds of problems out on the road when it changes as you drive.

You have a Float that is not closing or a bad needle and seat, my suggestion is to rebuild the carb reset the float and you will be good to go.

since u provide no real usable description of this noise it is very difficult to provide any precise help
