1980 TS 185

I converted both our PW50s to premix. I just disconected the oil pump inlet and outlet lines and then hooked them up together so that there is a constant cycle of oil running around the pump.

As for fuel mixture 32:1 should do. 125ml to 4 litres of fuel.

No, There is a small amount of oil in the pump that will go round and round if you join up the hoses. Just drain the oil tank or block off the outlet. On the PW’s I took the tank off completely.

The reason I joined up the hoses in the first place, was that I might want to run the oil tank again in the future and it just stops the pump from running dry.

A very knowledgeable 2t tech bloke recently told me that it is the oil that determines the mix ratio not the bike.

So whatever the oil manufacturer recommends is the go.

Little word of warning SOME self oilers have a bearing recess that will get no to very little oil from premix as the gallery is a bit funky in design, just check this out first, personally I’d use the self oil function once set up they’re pretty damn reliable on the old ER185.

I am with Mr Blue why remove the oiler if its working? They are reliable as the day is long. The bike was designed with it, they work great, our pee wee had one and it worked great. I couldnt understand why anyone would remove it unless they were racing them hard core. If I was to remove it Jak I would remove the pump and fit a plate like Badbowie said. The KTM 50 we owned here had the auto system removed and it was plated, seemed like the best way nothing to leak, go wrong, have the pump run dry, etc

Only my opinion
