Here are some new issues with the GS, I can only find one rear turn signal wire, and all the turn signals have been cut, not too big of a deal, but when I activate the turn signals, the bulb just stays on, and no blinking? How can i troubleshoot this?

Also I am replacing the fork seals, I have no power tools and am using the replacing fork seals how to guide, but when I turn the allen bolt on the bottom of the fork, it just turns and turns and turns, kinda like I need to be holding on to something on the inside. I can hear the spring twisting too, as I turn this bolt. Is this because I am using hand tools? Also how do I drain the oil on the throttle side fork tube? I don't see a drain due to the pinch bolt. Any suggestions are greatly appreciated.

Well here I am, a new GS owner. My best friend Brion was a GS owner, purchased it for his first bike, and was an excellent first choice in my opinion. The GS is my 3rd bike. I also own a 2001 monster 750, and a 2002 Ducati 998. But I must say that I love them, and appreciate the enthusiasm on this board. I previously grew up and lived in Asheville, NC, but have moved to Las Vegas, with absolutely 0 fun roads compared to asheville. Anyways, hats off to you all for such great info about this wonderful motorcycle!

I have recently bought a 1990 GS500E, which was poorly maintained, and  the previous owner bought for the sole reason of taking the motor and putting it into a trike. Luckly he mis measured, and all is still intact with this little attention deprived GS.
I have been working on the little guy in my spare time, re connecting wires and such, but have a few questions to ask the talented viewers of this website about things I am having trouble with. I have all the wires plugged in that I can comprehend. Can you guys answer where these wires plug into? I understand these are the coils for each cylinder, but where do they mount? Anything else need to be done to them for operation? What are the two little plugs near the head tube plug into? How about this snap in plug that comes off the main harness? Is there a rear brake, brake light switch? if so where is it? I'm sorry but I don't know how to post pictures here, so I'll give you all a link. Thanks for any help!

Also, I plan on coring the exhaust, and adding a K&N pod. Gotta get it running first though!

Here is the link to the pictures, as I have not yet figured out how to post pictures on this site. Thanks again!

Hey! Welcome to the board! You've chosen a wonderful bike to be with, as it will serve you very well. I like your other bikes, too!

Anyways, I'm not sure about that first picture, but the second and third picture there actually go together, from what I remember. The little wires at the front near the steering head connect to the black cylinder in the third picture. I'm fairly certain that they go together. If not that, then the little wires connect to tabs that are mounted on the frame in the front. It's one of those two, if I remember correctly.

Maybe I should avoid trying to give advice if I'm not certain, huh? :lol: I've seen those before, though...

Hey X5!!!
Thanks for the quick response! I love these boards. I have really enjoyed the Ducati forum, and have been eyeballing this one since helping my friend over the summer with his. You guys are great! Hmmm, I don't know if I know exactly where to go with that advice. So are you saying that the two plugs, plug into the coils? Also where do the coils mount? As of right now, they are just loose and doing their thing. The first picture was not in focus. Sorry about that, its a female plug, that has 4 connections on the inside. It presently, and I have no idea if accurately, above the right side, or brake side rearset. Thanks!
-Patrick

Yes. I'm fairly certain that they slide over the metal tabs on the cylinder. They should be near enough and they should fit. If they don't, let me know. I'll try and look through my manual to see what I can figure it out.

welcome to the circus. the coils mount to the frame as in pic.

Alright, well, I was right. It was just the second thing I said. Yeah! Go davipu! Woo! Alright!

so in the state the coils are in, in the picture, you guys don't see anything else that needs to be plugged into them or anything? I should just mount them to the frame? Thanks for that picture. It will also help with figuring out how to route wires and where to store them. Does my bike have a rear brake brake light switch, as it is now, when the rear brake is pressed the tail light does not brighten.  Any ideas about the two little plugs around the head tube? Thanks guys!
-Patrick

No no. Now that I read davipu's message, I think those two little black wires plug into the coils. Check it out, though. If it fits, then it probably goes. They usually don't make plugs that fit more than one thing, from what I've gathered.

The rear brake light switch is actually near the rear brake pedal. I think it's behind the heel guard, but I don't know for certain. It's down there though.

the two little ones around the head tube look like the clutch switch ones, or they could be aux wires that go into the headlight bucket, depending on length.  and that other female one looks kinda like the brake switch one, that goes from the light to the switch box. I gotta pull my 90 apart tomarrow morning so i will look then to see what I can see.

Davipu: Your late night source for definative GS information. That's right folks, he'll clarify anything you want! He even makes Julienne Fries!

Ok,

Well the first pictures plug was for the brake switch, I found it and plugged it in. The coils mount to the frame through the two holes on the end? Is there a spacer between the frame and the coils? I think i've got a handle on this. Thanks guys. I still haven't figured out where the plugs next to the head tube plug into, if anywhere. After this I have to figure out turn signals. all the wires were cut at the turn signal, (fun fun) Also, confirm if this rumor is true or not, but my friend says their is someone on the board that will sell me the jets needed for re jetting to 140's, etc etc, with the allen screws and washers too basically everythign I would need. I am new to vegas so it is hard for me to hunt down the washers/jets/screws for this. I think he also said you can send the carbs to someone and they will re jet them, as well as clean them. Any truths to either of these? I guess that is it for tonight. Hope to have it running soon. One more thing, can someone explain to me how to post pictures in here?Then will be the task of cleaning it. thanks for any advice you can or have provided.
-Patrick

PM Srinath for jetting issues and supplies.    and read the FAQ for pic posting info.

I figured out the wires in the first picture go to the horn, What a lil wimpy horn. Thanks for the help thus far guys. The chain was given to me in a shrink wrapped bag, I went to put it on, and its SHORT!!! The axle is all the way forward and I could still barely squeeze the master link in. Contacting the previous owner for links, or a chain. I hope they didn't ride around for awhile with the chain this tight, its horrible.  Got the GS to turn over with everything hooked up. Now I need to replace the fork seals, mount the pet chicken and connect fuel lines, take the carbs off and clean them since they've been sitting outside, clean out the goop from the countershaft sprocket area,re wire the turn signals,  and give it a bath, and it should be ready to rock! I'll be glad to have this little guy working, I may also try to put a spacer in the forks if I can find something to use, I can't find the nylon mentioned in the how to part. We'll see, but its on its way, and I really enjoy working with the little guy. I should name it soon. Thanks for the help

Some help with the top part of the first post please

Check connections to the turn signal relay located  just ahead of the rectifier\regulator  on the right side.
The allen bolt can be a pain to open,best way to do it while the forks are in situ on the bike , but it seems not to work for you. Anyways, you'll have to remove the forks to drain the oil , at this point leave the fork brace on one of the forks. After removing the cap and draining, find a lenghty rod or a stick (broom stick works fine),insert it into the fork so it rests on the spring spacer,invert the fork and place your leg on the fork brace,compress the spring inside as hard as you can whilst trying to open the allen bolt,it can be a struggle but it eventually worked for me.Repeat for the other one.
Hope that helps

Neither allen bolts came out, so what I am trying to do is compress the spring so that the bolt will un thread? I was doing the project with jackstands and the forks still on the bike, so what do you mean "try to do this with the forks sifu" Thanks for any additional help. This is quite a project. i'm guessing that I now have to remove the legs from the triple clamps, but I have no vice. I'm stuck.
-Patrick

You can do it without a vice just as I described above.
I had to rebuild my front forks totaly and i did it  with the simple tools i have.
It's no big deal to pull the fork legs out and work on them individually,it's easier IMO.  You should compress the spring enough to stop the rotation of rebound damper inside,allowing you to open the allen bolt.
If you're doing extensive work on your GS  Haynes manual can help a lot by the way.
There are many threads about the forks, use the search option and you'll get plenty of additional info.
Here is usefull one:

Check out starwalts ckt diagram . You'll have to compare/find the wires and hook them up per the diagram.

Is it necessary to remove the allen bolt to change the fork seal. This is getting frustrating, sorry, but none of the suggestions so far are working. Maybe this thing is just too old.  i have no idea how i'm going to get this out. Is there something else that can be stuck in there? Sorry had to vent, If its not necessary to remove the allen (though I really would feel better if I could tighten it back, let alone remove it) I will just change the seal add oil and be done with it.
