Ok, so I'm trying to do some white spacer modding (of course), and it occurs to me that I have free access to a bunch of 3d printers, and that this might provide me a free source of new spacers of any size I want.

My only real concern before trying it is that the resultant spacer won't necessarily be all that strong since it will be at least partially hollow.

So, two questions:
1. How much "squash" does the spacer have to deal with? Would semi-hollow plastic stand up to the task?
2. Does anyone know off-hand exactly what the measurements are for the internal/external diameter of the spacer?

Not a good place for a science experiment.

Why would you? Ace is the place ! buy the washers! your making a mountain out of a mole hill!The spacer is a white donut shape and plastic, mine has a "cast" line running around the outside at the center.You can just sand it down ,and put it back in.

Go to www. RON AYERS, site,pump in motorcycle ,Suzuki ,your year ,model ,and look at the exploded view of the carb .That will show you the washer and where it goes ,you can even order one,if you wish. part # 6- $4.14  It must be the PO took the the spacer out .Do you really think you can design an print these in an hour?Are you sure the plastic you use will put up with gas?Is an hour drive to much time out of your life to get right the first time?I don't know what the S stands for ,the thickness is the most important measurement,stack 4 of them and see if they measure 1.10 mm. /0.10 inches , if they do use 3 if you're above 1000ft in elevation ,2 if your between 1000ft and sea level.

True - quite probably not gasoline-friendly! Although I think at least one of our printers can print in metal...
It's just a disc with a hole in, right? It's a simple geometric shape with defined dimensions - it would take about 5 minutes to design it and print it. Anyway, since (a) the material may not be right and (b) the washers I have are actually the right size, I can drop this line of reasoning.

Looking at the exploded diagram (and the one in Clymer's, which is the same?) I think I did find the white spacer yesterday, but I guess I just don't see what to do. The spacer is narrower (smaller diameter) than the photo on the walkthrough and fits into the hole at the bottom of the tube. If I replace it with washers, they won't fit into the hole and the plate won't screw down properly.

Alex ,when you take out the two small screws to remove the plate the next thing you see should be the spacer ,sitting on the top of the needle jet .You remove the white spacer and insert 2or3 washers.

I bought #4 brass washers once - and the outer diameter was too bit to fit in the hole.  The proper #4 Machine screw steel washers work fine.......You should get some!

Update: the washers from Ace didn't fit right either, but while there I thought ahead and got sanding supplies too, so I ended up sanding about 1/3 off the spacer and reinstalling it.

Then I went for a ride, and might have been witnessed emitting a string of involuntary "BWAAAAAH"s when rolling on the throttle...

Good God but it's amazing what getting rid of a tiny bit of plastic can achieve...
