Hello everyone,
First of all I appreciate it that you are taking the time to view this thread. I'm in need of really serious advice and suggestions so again... any help is highly appreciated.
On Saturday night I took my 2002 GS500 out for a ride. Everything was great until I noticed my engine kept turning off while I was decelerating! I knew this because I saw all the lights go dim and the tach/speedo needles dropping from 40 mph to zero while I was still going at least 30+ mph! And rolling on the throttle did nothing! This happened several times... I finally just called it a night and went straight home because it was getting too dangerous. And I wasn't even decelerating very fast. I just rolled off the throttle and just as I'm about to push the front break lever... the engine dies!
PLEASE... I don't understand what's wrong? Has anyone else had such a problem? Something is severaly wrong with my bike if the engine dies on it's own like that.
Please... any advice is appreciated. Thank you in advance.

First thing that comes to mind is side stand switch is opening while you are riding and cutting the power to the bike, an more so since the fact that a deceleration would take the pressure of the sidestand switch.
My reccomendation would be to check the side stand switch, or if you want you can jump it with a paper clip(on the connector) and go ride and see if it does it then.
Side Note: Does the 2002+ have electronic speedometers?
Ohh yeah, incase you did not know, there is a safty protection circuit that does not allow you to have the bike in gear and the side stand down, so you cant ride of with the kick stand down and kill yourself.. :laugh:
One other test that you can do with out having to do anything is to put it in first gear at a stand still, with the clutch pulled in and put the kickstand down, see how far you can move it before the engine dies. If you only move it a tiny bit and the engine dies then what you can do is accelerate heavly in first gear, and then go to nuetral, and hit the brakes hard, repeat it again but goto second gear and hit the brakes hard. If it dies when you do this in second gear and not in nuetral than your problem is for shizzle the side stand switch.
The 02 GS speedo and tach are both cable driven. No way speedo could go to zero while moving 30+ mph and no way tach would go to zero with dead engine unless clutch was disengaged. Broken or disconected cables wouldn't re-engage and repeat several times?
Don't think we're understanding the problem at all yet.
I had the tech go to zero while riding...and the bike/engine runs perfectly...i thought it was a loose cable...but turns out it was the battery... :dunno_white:

04-05 with electric tach?

this happened to me once too but it wouldn't start up again and that was because the fuse had blown, so check that just in case although i don't think it would start up again with a burnt fuse. also, i made a huge newbie mistake when i ran out of gas! sounds silly, but my bike had the same problem u described when i was out of gas. check fuel in tank then put petcock to reserve if there is some fuel left. lastly, check the battery. it never hurts to put your battery on a slow charge of 1 amp for about 10-11 hours. motorcycle specific battery tenders work best. good luck!

How about the battery connections? Are they tight?
Ok, here's my experience that will make ur head spin if u were thinking that it might be a petcock issue.
I had a bad petcock issue many, many moons ago. It was some weird kind of high rev issue...didn't clear up until I ran my fuel line straight to the carbs. Then I ran a "T" fitting with a screw-in type petcock from the reserve.
Problem was solved until I went to visit Davipu and install a GSXR rear shock. Then the shoot hit the fan on the way back...bike ran like COMPLETE crap in the POURING down rain for 150 miles. Would stall over 60mph. And I couldn't see shaZam! because I was retarted and bought a smoke helmet lens...
When I got back I took the carbs apart and reset the floats which were about an inch off...kidding...but at least 4 mm...ridiculous...
I wrecked the bike a couple months or so ago in the rain going around a corner...got too comfy and lowsided...but up until then I would get starvation issues at high speed as well even with the fuel lines running straight to the carbs without a vaccuum actuated petcock...So it must be a jetting issue and I think the solution is to add another washer to the needle....havn't done it yet but I will try.
Bumping this to the top....anyone know what success other people had with the adding the washer?
