Thanks john, i was looking on the Honda web page and found 4 stroke oil and it said buy 20-50 for my climate, so i thought that was for the final shaft. But at pep boys i asked and they said no, no that´s for the motor! So i changed that and asked the oil for the shaft and they told me for PR the 85-140 is the best. Now i filled it to the top of the nipple is that correct or is that over filling it? It only took about 3/4 of the bottle.
