Automatic Chain Oilers

Chain Oiler is an on-board, on-demand chain oiling system.
You lube your chain only when it's needed, which means you control the process.
With this Chain Oiler, there's no need to run a vacuum tube from the carb or fuel injectors to the reservoir, and there's no complicated electrical connections.
Your chain and sprockets will last very long when they're properly lubed.
Extention bracket included for moving the unit up by 15mm, providing more clearance from the mounting. 
Multiple colors available.
Comes with instructions.
