Curious to see how messy it will be...I guess when you get the flow dialed in it shouldn't be and issue....don't what to think about these automatic Oilers, ran chain driven bikes for many years and really didn't spend much time lubricating a good quality chain...a shot of chain lube every 300km or so and the odd cleaning when it got to much gunk on it...and always had 30 ish thousand km before having to replace it with a fresh set....if you personally has me ...Im sold on a belt drive system...anything under 100hp and is riden on tar mac.. (.street bikes )..
