Title: Got a little problem hope you guys can help
Post by: hoggin on October 03, 2012, 03:06:33 PM
Sorry if someone else wrote this before but I have serached and can't seam to find an info to here it goes.
I purchased a 1995 GS500E rode it home fine just had to jump start it. did notice the idle got high after it watmed up, ( no biggy) but after a day of riding it I noticed the tank leaked a little gas (had a small crack on it did not think it leaked when purchased), So I took the tank off to fix the leak and then put it back together and now it will not start. Cranks over fine just will not start up check everything so far even had a mechanic rip me off anff still could not fix it.
Any little info would be great thanks guys. Gob less

Did you turn on the tank shutoff valve?

yes I did that wqas the first thing I checked

Put the petcock on prime and check that you are getting fuel to the bowls by opening the carb drains to check for flow.  If you have flow,  then attach a clear tube and bend it up to check where the gas level settles.  If its not even with your float gasket then you need to adjust or replace your float needle valves.

Gas in the tank?
You're not saying how you fixed the leak.
Did you coat the inside of the tank? If you did, did you remove the tank fuel valve first? If you didn't, you probably coated it and clogged it up with the stuff that coated the inside of the tank.

Test: Pull off one of the fuel lines from the frame petcock. Does gas come out? If so, put it back on. If not - then you have problems with the tank fuel valve or the screen filter inside the tank or you don't have gas in the tank (yes - I have actually seen that in person!)

to chck the flow do I have to try and start the bike or just open the drains.

I just used some JB weld from the outside of the tank not the inside,

Put the petcock in the prime position and then open the drains. The prime position allows the fuel to flow freely and does not rely on vacuum as the ON and RES positions do.

Thanks bsheppar i did ur idea and noticed fuel come only from 1 carb should it come out from both carbs.
Title: Re: Got a little problem hope you guys can help
Post by: mchollan on October 08, 2012, 03:08:30 PM
Yes, fuel should flow out of both drains.  The carb that isn't draining you probably have a stuck float on.

or the drain hole is full of crap, which is a bad sign anyway.

Thanks guys I did it agqain and it did drain out fo both sides, someone told me to check the spark plu gap, Does anyone know what the gap should be?

You could try taking the carbs off and spraying a little starter fluid into the intakes and see if she tries to fire. But first, I would make sure there's spark at the plugs. If you're getting spark and it tries to fire with the starter fluid then everything points to a carb issue not providing fuel to the engine.

How can I check to see if I am getting spark to the plugs
Title: Re: Got a little problem hope you guys can help
Post by: Funderb on October 10, 2012, 01:24:42 PM
pull off a plug cap and crank the bike, if it shocks the shaZam! out of you the coils probably good.
:thumb:

or you can pull the plug, stick it back in the plug wire, hold it against the engine and crank, look for the spark there.
Best to do it in the shade/evening

How to measure spark:

1. Tingling in finger = weak spark.
2. Jolt up the arm = ok spark.
3. Singed hair and burning flesh smell = your good to go.

LOL...been done that.  Not for people with heart conditions.

Thanks all I will try to see if I get spark this weekend.

Pinky in plug wire thumb on the cylinder.  O0 < your hair will look like this.

OKm so I got no spark I think it might be the CDi box? Any other suggestions will be helpful.
Title: Re: Got a little problem hope you guys can help
Post by: hoggin on October 18, 2012, 07:31:43 PM
Ok put in cdi and i still have no spark. Is there anything else i can check?
Title: Re: Got a little problem hope you guys can help
Post by: RickM on October 18, 2012, 07:45:16 PM
Did check the coils? Coils are more likely to be suspect than the cdi.
Title: Re: Got a little problem hope you guys can help
Post by: hoggin on October 18, 2012, 07:49:16 PM
How do i check those rickm? (coils)
Title: Re: Got a little problem hope you guys can help
Post by: mchollan on October 19, 2012, 09:16:31 PM
Use a multimeter to check the resistance of the coils.  There are two coils per side.  A primary and a secondary.

The primary can be measured by checking the resistance between +wire and -wire on the coil pack.  That is the black cylinder looking thing bolted to the frame the the plug wire comes out of.  It should measure 3-6 ohms or resistance.

The secondary coil can be measured from the +wire to the plug cap and be around 18-30 Kohms.

+1

Btw did you check spark at both cyl. Its unlikely that both coils went out at the same time. If you have spark on one side you can swap the good coil to the bad side and confirm that way as well. Another possible reason for no spark is a bad timing pickup coil or connection from the right side engine cover area.

Yeas rickm I checked both sides and there is no spark on either one. I also noticed that the starter switch was always a little tricky I had to push on it kinda hard since I got it. if you push it lighty sometimes it will not work, Could this cause the problem?
Title: Re: Got a little problem hope you guys can help
Post by: Funderb on October 22, 2012, 09:40:19 AM
also its a good idea to check the resistance on the signal generator, mine failed on me all of a sudden. all you have to do to check it us pull the left tail fairing down a little bit, here's the page:
