image from ebay, not the bike, but same shape. monster 1000ds with multistrada reservoir the diaphragm wont stay retracted. as a result, very little space for fluid. i dont see the diaphragm listed as a part. is it available to buy on its own, please? has anyone sorted similar issue please ... i may remove it at the weekend, immerse in solvent, dry for a while and see whether it will then stay retracted. also need to find where the fluid has leaked.

You can substitute the diaphragm with fuel tank foam. Fill the whole reservoir. Takes up 3% volume and stops the fluid from sloshing around. Here is an example https://ebay.us/m/sUmkW6
