@Murdo @maelstrom Hey guys I've managed to pinch some diaphragms and now have a tiny pinhole in one. Has anyone repaired one before? The internet has led me to thinking it can be done. Polyurethane glue and nitrile rubber from disposable gloves seems a possible way. Thanks Tyson
Kiehin cvk D38s only bike that uses them is the zx7r. All my searching I couldn't find replacements as they are all one piece with the slide. The price was from millway spares and was the cheapest
Yea still fairly expensive at about $50 but at least they are around if all else fails Take a few pics of your repair job Some of my FZR ones were patched up .... pretty dodgy though and they were on their last legs anyway
Ok guys i finally got around to giving this a shot. First up was diaphragm removal. you can see where this was pinched, (stupid hasty me) Both of these items are from bunnings, the gloves are nitrile so are fuel and heat resistant and thin and very stretchy and flexible. Polyurethane glue is solvent resistant and dries flexible. So i cut a small square and rubbed a fine even layer of glue onto it. the placed it on the pinhole, then repeated as 2 were pinched. above is my engineering to ensure they dry flat. in 3 hours i will hopefully have airtight diaphragms again.
I'd be hitting up wreckers to find another. The last thing you want is fuel to eat away the adhesive and that to end up somewhere in your carby. Good effort though...
Probably OK "vastly resistant" heh. http://www.engineeringtoolbox.com/polyurethane-chemical-resistance-d_1878.html
I've been using nitrile gloves for painting & the rubber looks a bit thicker, get them from the auto paint shops. Bloody nice work, if it hangs in there, you've saved good money. I've got an XS1100, next project, & the carb diaphrams are bad, $150 ea, so i'll be following your lead with them.
