Repairing Torn Diaphragms
« on: November 23, 2009, 10:27:02 AM »
Has anyone had luck using Hondabond or Elmers Probond to repair torn diaphragms?  Are there any other methods I am unaware of?  At $100 a pop, anything is worth a try.  Do Mikuni carburetors have slide diaphragms as well as it may be cost effective for me to switch these carbs out at this time?  Thanks for any information.

I  had this happen with my FZR. I just bought a used set of carbs from ebay and used the diaphams from it.

Yeah, mine are probably too bad to even mess with but I'm CHEAP.  So I am going to try and rehab them with a bonding agent.  I will post my results but don't hold your breath on this working out due to the terrible condition they are in.

I used contact cement on my GPZ carbs. Still runs perfect 10 years later.

What he said.  ;D

I used some silicone gasket goop to fix some on an old Kawi, worked fine.

Mine was too bad to salvage, it more less fell apart all the way around. I shelled out the bucks and ordered a new one but have some Hondabond if my other diaphragm ever gets pinholes.
