Where can I buy a cheap oil leak ?

I appreciate not all of you are familiar with chains, especially non sealed ones with a split link.
You might think this a bit strange. All my old Triumphs vented oil from the engine breather onto the rear chain, so kept them oiled and in good condition. In response to all those that called these breathers, oil leaks, my new Enfield does not leak. It is completely dry. So was the chain, and it has worn out in 8k miles. I fitted a new one today of hopefully better quality but I also need to buy an oil leak to help increase chain life. I beleive they are sold under the name of 'scottoiler' and other names. Just seems wrong to have to spend money to create a leak. I guess fashions go in circles. I have no doubt that in 40 years time they will have great advances in motor technology and invent engine breathers that lubricate chains. Probably be a thriving after market for 'small bore kits' to make engines run smoother and more economically. Who knows they may even invent rear wheel stands so you can remove/replace the rear wheel without lying a bike on its side.
To get that function back ie an oil leak, will cost more than the price of a new nicasil alloy barrel and piston or a crankshaft and conrod assembly. It just does not seem right that it should cost that much to buy an oil leak.
I would rather they reverted to a timed breather onto the chain. Because one model ( computer controlled with more computing power that existed in WW2) according to its users is very dificult to get set up right. It either runs dry or puts too much oil on which gets splattered all over the rear wheel. Seems like 60 years of technology still cant produce an oil leak functionally better than was available then.
anyone know where I can get linklife or its equivalent?
