depends on ur flow..... u can adjust the flow of the scottoiler...they recommend 2 drops per minute iirc... but thats too much imho to a point where the flinged off oil  thats collected at my chain guard will drip to the floor when i park my bike. i set mine to about 1 drop every 1.5-2 minutes.

chain remains oiled, cleaned and no drips... still some oil stains on the chain guard on wheels.. but thats normal.

U can check with hodaka motoworld in pjcc. N theres a couple of sellers on shopee.

Theres another bike shop in kl... sells scottoiler n its parts..quite famous but damn i forgot the name.

If u have biker friends who go singapore alot...can ask them to get for u..i get mine there. Much cheaper but dunno if price increased or not coz last time i bought was before covid.
