Okay I search ed but couldn't find it.

i need to do a rebuild of my carbs because the last owner's rebuild was a disaster.  New is wasn't right when I bought it but bike was a steal. currently I have a DJ kit but even that was not installed correctly.  They modified the slide with the drill but didn't put in any of the compensator in the new hole. I think I have found everything to go back and do it right but I can't seem to find what the original needle jet is supposed to be.  I think it is an mikuni O-3 but I can't be sure.


Stock motor:
So I am going to get new slides $ouch!
40 pilots
125 mains
original needle (with washer)


Is there a way I can repair the slides?  What side should the holes be?  I can always fill the holes and re-drill to the correct size.  Could save me a lot of money.

Thanks

What year is your GS engine? What about the frame? Where are you located? People will want to know those things if they're going to provide you parts or advice.

Check this parts diagram:

It is for a 1997 model GS, but the two-stage carbs are the same from '89 to '00, so anything you see there is correct.

You can search for your specific model details on any one of dozens of online parts fiche diagrams; MRCycles.com is as good a place as any to start:

http://www.mrcycles.com

RonAyers.com is also good:

And of course, there is always Suzuki Parts Nation:

http://www.suzukipartsnation.com

among a TEEMING MULTITUDE of others. The thieves at BikeBandit.com usually charge higher prices, so I suggest you avoid doing business with them. Friends have had customer support problems with ElBanditos over the years, but since none of them buy anything there these days, I don't know if those issues have been addressed.

Just go to the Suzuki parts section on one of those websites, find your year, make (Suzuki, right?), and model (I think you have a GS500E), then open the carburetor page. You'll see the parts list there, including retail and discount prices. OK, I've wasted enough time typing dumb old Y/M/M jokes...

In the parts diagram, part number 18 is listed as the JET, NEEDLE (O-3M), Suzuki part number 09494-00871, selling for $30.98 EA, not including any taxes, shipping, or handling charges. DO NOT be quick to buy a new one; The Buddha might have what you need just waiting for a new owner. If he doesn't have it, someone else almost undoubtedly will.

In that same diagram, you'll see TWO parts with the number 14; the ACTUAL part number 14 is an O-RING, which is easy to lose, or forget to install during a rebuild. I keep a few extras on hand, just in case, and you might want to order an extra one in the event you lose one of yours.

The WRONG number 14 is shown as a CAP which goes over a port on the diaphram cover; it is actually number 10, NOT number 14. Again, do NOT lose those caps; I keep a few extras on hand...

I couldn't begin to guess at the size of the hole in the slides, and I'm not willing to disassemble a carb tonight just to find out; besides that, I have nothing to accurately measure the hole with. However, The Buddha can probably tell you what drill bit to use. You can fill the hole with epoxy or JB-Weld or something similar, but you'll have to be VERY careful not to damage the surfaces of the slide and to polish the filler to a SMOOTH finish. If you scuff or score it, your slide won't be doing very much sliding any more.

Hopefully, Buddha will see this soon; he's on the East Coast, so you'll probably get a reply from him sometime tomorrow morning. The Buddha sells a LOT of good stuff at great prices, so I'm willing to bet he can sell you some quality used parts and save you some cash.

Though you've probably already seen it, I feel obligated to mention the wiki:

http://wiki.gstwins.com

A LOT of people have worked to make the wiki a helpful resource; don't overlook it.

Lastly, the FAQ section has even more helpful goodness on every page; some of the information is in the wiki, but look through it anyway:

http://gstwins.com/gsboard/index.php?board=7.0

Yes, I realize you've probably already seen the wiki AND the FAQ section, but other new owners who read this in the future might not, so this is intended more for posterity than any other reason.

Good luck; keep us posted on your progress so we can help you get your GS back on the road soon.

If you're going back to stock (or stock with slightly bigger jets) and dishing the DJ, then There shouldn't be any holes in the slides, apart from the small crescent at the bottom.

Thanks for that input, Brendan; I'm so tired, I couldn't remember if there were holes in the stock slides or not... slides with holes, slides without holes, I'm so confused...

Brendan, the God of GS5 carb slides... I owe you beer for this...

No biggie.  I just happened to go through the rejet process a few months ago.  I had considered the DJ, but most of the forum members seemed opposed to it, plus I didn't like the idea of drilling the slides anyway.

Stock Slides have holes, 3 of them. DJ makes you block 1.5 of those. The third is the center one for the needle.
You dril lit, then tap it, then plug it. 
Cool.
Buddha.
