DT125R FORUM

Autolube is being run by engine and more rpm, more oil you get. Ofc, throttle adds more oil because autolube piston travels more.

Did you guys experiment how much oil autolube should push to the engine? Watched this video and not sure if it is correct amount for my motorcycle.

Oh it helps a lot. Thank you!

Hi guys,

Previous owner of my DT125R 1989, decided to use premix instead of autolube pump so he just disconnected oil warning light, emptied 2T oil tank and filled petrol tank with premix
I have no clue how many miles he had with this setup and since this is my first 2T bike (had many 4T in the past) I have some concerns and maybe you can help:

1. Is 2T oil is also lubricating autolube pump? If so, what parts should I inspect to see if there was some damage done because 2T oil tank was empty for xxx miles?
2. If I continue to use premix, do I need to put bigger jets in the carb because premix thickness is not the same as just petrol.
3. With 30:1 premix, does engine get enough oil on closed throttle?
