This tip isn't for all of you , some of you have plenty of cash and like to spend it, if that's you then feel free to hit the x in the top right corner of your screen , it isn't for you.
If you own a Yamaha and have ever pulled apart a carb you have seen old crusty main diaphragms that felt like cardboard , I have thrown hundreds of them away just like that.
If the diaphragm has pinholes , you can see daylight through it , it's obviously worn out , damaged , stuck to the metal or hard as a brick bat then replace it and move along to the next thread.
But lets say you pulled it apart and the diaphragm isn't quite as rubbery as you would like , maybe even a little stiff and more like paper instead of rubber , and hey you want to go ride this weekend and not wait around on parts, you can fix that and you can fix it very cheaply .
You need two things brake fluid ( it doesn't matter what kind cheapo brake fluid works just fine) and a container to put it in that will hold the diaphragm, drop the diaphragm in the container , pour brake fluid till it covers the diaphragm and let it sit overnight. You will be amazed at the results , I tested some that I was for sure were too dried out to ever work again properly and it brought most of them back to life.
To be clear , this isn't something that I saw somewhere on the internet or something I read about , it is something I have thought about for a while , I tried it and it works , but please don't take my word for it though try it for yourself .
