Scot didn’t recommend the idea but the oilers can be fitted to the front sprocket on the underside. That gives more time for the oil to seep into the chain before it gets thrown off by the back sprocket.
I did this on an MZ 250 which ate ordinary chains in about 10,000 miles. They were not expensive to replace but the job is a pain in the arse and very messy.
A half worn chain, with the front mounted oiler, never needed another adjustment and was still going fine 17,000 miles later when I sold the bike.
Doing it that way gives a shorter vertical feed tube that feeds very consistently and lets you put the oiler unit by the headstock where you can see if it’s feeding correctly. They are prone to dump the lot in 100 miles.
If you change your mind just fit additional tubes to feed oil at the back end.
