Cylinder Head Rubber Pads

My 1978 gs750 engine is ready for paint, then reassembly. I tore the top end apart for a rebuild. I am getting ready to order all the gaskets and o-rings that I need, and came across these Cylinder Head Rubber Pads.

It says I need 18 of them. I do not remember seeing these when I removed the Head. Can anyone tell me what they are, where they go, and do I need to replace them, or can I use my old ones if they are in good shape (once I find them :oops:)?

Thanks!
 
Not necessary.
They are sound deadeners left over from Suzuki's ring, ding, ding days of 2-stroke engines.

Actually those little rubber pads are a press fit in between the vertical cooling fins, I guess for vibration isolation. Don't see too many bikes with a complete set, but see alot of bikes without them. If you're a purest you'll probaby want them though.
$1.59 each at Boulevard Suzuki.

If you look real closely around the vertical fins in between the 3 and 4 spark plug you can see them (barely) in-between the vertical fins ('79 GS1000E).

Thanks Eric,

I thought maybe they were the pads between the fins on the head. Good news anyway, it saves me $27.00!

That's exactly what they are.

Suzuki superseded the original black pieces with gray. I ordered some in an attempt to replicate the original look on my first S, but was disappointed when the parts arrived - never installed them. Wonder if I could dye them in some concentrated Ritt dye?

You just saved me from ordering something I wouldn't use either. I guess I'll have to find some sort of substitute material to use in place of them.
 
The GS1100E uses a similar item for the horizontal cooling fins. They're all attached as a string, and they're black, I have a couple of new sets and was thinking of cutting them to size for my 1000.
Wished I had time to take a pic of them (none on E-bay) before I rush off to work, anyway here's my bike that shows two on the head.

With his 1100E, Steve is like a guy with a "trophy wife" - he just can't show her off enough and I never get tired of checking her out! Absolutely gorgeous! :lol:

Agreed!!!
Don't be stingy with those pic's of your bikes! ;)

Youll notice that they are wedge shaped at on end..wedges apply outward force..like splitting wood. I insert them all in between the fins finger snug and then give each a gentle tap to kinda stick them in.. I dont know that one could actually snap a fin with one, but maybe i just think outside the box too much.
 
If they werent all cracked, a simple rubbing on some 800 will spiffy used ones up very nicely.

I couldn't see much use for those things anyway, maybe they were there to help keep from breaking a fin, otherwise to cushion the vibration, don't know if they did any good, all I see is something there that obstructs the cooling air flow. Wonder how many I'm missing? Haven't bothered to even look. Need to pull the new GS1100E ones out and see if they'll possibly fit, then all I would need to do is cut them to the right length. I think they could work.

Use rubberized bumper spray paint. I have used that on all the black plastic peices in the past (handle bar pads, "glove" box liners) looks pretty good. Anymore on plastic I use a heat gun to bring the dye back to the surface. Which works really well. But since those are rubber they'll probably look perfect with that stuff.

Wonder about a sparky, think a black indelible felt tip ink marker would work?
 
Those pieces are definitely some sort of rubber, although the new gray type feel a little plasticy.

I'm going to try the Ritt dye first and see what happens. I've dyed plastic before with that stuff and it really gets inside some materials. To be honest, I don't really care that much either way and not sure I want to resort to painting or coloring those pieces with something that's going to fade or scrape off easily. I'd forgotten I even had them until this thread hit the screen.

I thought they were rubber, I mean in the fische it say it's a "rubber pad"
but when I checked my 1000 out, it felt like a feather light hard brittle brick material, like a charcoal, they were grayed. Don't know if they're located where there supposed to be, one fin has two different heights, one has none, others one, same on both sides, 18 of them there though.
I pulled my rubber pads for the 1100E, under the the revised part number they come in a interconnected strip of nine (The bike uses 4 sets of 4 interconnected which are black) they are dark gray and feel like hard rubber to me, they are about the same size as the 1000's, rounded on one end and wedge shaped also. I'm thinking they'll work for the 1000 also. Since my 1000 has 18, and my 1100 already has a very nice set, I just think I'll mothball these as you have done to yours Ed.

Those pieces have arrows on them. What is the significance?
Which way are they supposed to point in each application?
Back on top and down on the sides?
