PO2797-1, KLR 650 DIAPHRAGM & SEAL KIT, PETCOCK, 96-UP Order Here
Leaking Petcock? The TPI Petcock Diaphragm and Seal is Original Japan, NOT Taiwan. Many diaphragms found on the internet are not Japanese and fail quickly when Ethanol comes in contact with them. That’s not to say Ethanol doesn’t destroy the Japanese product because it does but the compound in the Japanese rubber is much more resistant to Ethanol. Ethanol is bad stuff folks, it can destroy rubber and a carb in just a few weeks. Running Ethanol almost daily does little damage, but let it sit a few weeks and you’ll be pulling your carb to clean it and eventually replacing the diaphragm and seal.
Note: Ever wonder where the name Petcock came from? Well read further if you do and if you don’t, go buy some parts. Petcock is an English term and it has nothing to do with your pet Rovers red rocket. It is short for Petroleum Cock, (gas valve to us USA guys). Petroleum for Gas and Cock for Valve. So, the next time you have a few too many in an English pub, you can say “I need to drain my beercock”. They’ll know what you mean and point you in the right direction.
