What glues would be good candidates to reattatch this diaphram back to the slide?? I was thinking regular hardware store contact cement..yes, no, maybe????

I would guess somewhere between NO and MAYBE.
Is that normally a press-fit? I have never had a GS diaphragm come apart, but saw that with my son's Yamaha.
The assembly was a bit different on that one, so it required a different fix.

Cant say for sure if its a pressed fit or the ends of the plastic posts were melted to peen them over like rivet at one point.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

What you don't want is something that will eat or deteriorate the coating on the diaphragm. I really cant say what as I've never attempted said fix. What size is it for? I may have one in the many spares I have laying about.Comment

No glue. The diaphragm is held by the plastic piece. How did you take it apart?Ed

I don't think he did. I think it was like that when he opened up the carb. I've seen it one time. And have no idea A) how it came to be that way or B) how one or what one would go about using to fix it....Originally posted by Nessism View PostComment

Josh is correct..like that when I opened them. They are BS34 flatsides from a GSXR1100. The PO tried to reapply it with what looked like black RTV but it didnt hold. I was lucky enough to take a rag and some carb spray and remove all the RTV from both pieces. Now the thing is to discover how to reattatch. I have thought about this all night at work.
Those two posts that pass thru the holes in the slide are what I think is ABS plastic..so i was thinking maybe a dab of ABS glue on the ends once thay are reinserted into the slide. leave it kinda beaded at the ends of the posts... What do you guys think of that idea?MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Took another slide out and looked at it under a magnifying glass. It appears that the original posts stuck thru the holes a bit and some kind of hot press riveting was made by mushrooming the excess that sticks thru. So the bead made by the heat pressing must get brittle after time and start chipping away and eventually releases from the slides. So basically I need to duplicate this. Heres as good a picture i could get of the heat pressed fitment.

Should work actually.
Another thing you'll want to check is the slide itself, as well as the plastic guides in the throat. A lot of guys say those carbs were "cheaped out" on by Mikuni and the plastic bit wear horribly... I think posplayr did a write up on rebuilding the tracks with aluminum sheet instead or something to that end.Comment

Use a flat soldering iron tip to mushroom out the pins. Should take about 1 minute and no cure time. Just make sure the plastic has cooled totally before you "test" it.Current:
Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)
Past:
VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
And a bunch of other crap Yamahas....Comment

Hillsy...thats the problem..the pins no longer extend past the face of the slideand theres nothing left to mushroom again.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Hers my decided on fix..First I drilled a small hole down the centers of each post. Then mixed up some epoxy and squished it into one end of the hole until it came out the other. Then i reset the slide to the diaphram and added a dab of epoxy on each side of the holes I had drilled thru. Now what I have created in effect is an "epoxy rivet" that runs down the center of the post..Just hope its strong enough to not release again...

Edit: Chucks post above came in while I was typing.
What about drilling into those two pins with a small bit, then using sheet metal screws slightly larger than the hole to flare out the pin and lock the slide together?
BTW Chuck, your photo links SUCK!!! Pop-up box city when trying to view your photos.Last edited by Nessism; 01-29-2012, 10:57 AM.Ed
