Over the years, I have known a number of people who have used Scot oilers.... they always seem to be happy with them. The biggest issues seem to come from getting the application rate correct.
Me, I'm too cheap for that. A nitrile glove, a clean rag, and a bottle of gear oil have been the only way I have maintained motorcycle chains for the past 10 years or so. Gloves are very inexpensive, a quart of gear oil will last multiple riding seasons, shop rags can be bought in bulk for almost nothing. Even without a center stand I can service a chain in maybe 15 minutes.:rockon:
If you keep the all of the outer surfaces of the chain covered in a light film of gear oil, water cannot penetrate, and dirt will not migrate into the rollers and damage the pins.
The film strength of the gear oil is far higher than the amount of force between the links of the chain, and the teeth of the sprockets.
If you doubt how well gear oil will stay on the chain, try getting some on your hands without the nitrile gloves, and see how much of a PITA it is to wash off.
I always wonder too, since it rain often here in Florida in summer time. Do you know what grade of Gbox oil they're using? I was thinking making my own with a little pump and giving it a squirt every now and then when it rain.
hmmmmmm....assembly lube?!
