I have a 1978 Garelli oil inj. but that is in name only. If your bike has a bottle on the side for oil with a pump on top it does not automaticly add oil. two pumps when empty fill with gas and go. I mix my gas in a can at the rate of 40:1. You must still mix one way or the other but a can is simpler. If you thought it was mixing oil automaticialy and it wasn't your lucky it's not froze up. e-mail me ifyou think I can help further
