yeah i just got back from an afternoon ride and noticed more mechanical noise then normal.. So i got home hopped off and was low past the add 150 ml mark. I had a 1000 mile sevice apointment set up for tomorrow but had to cancel dew to work. Then closest day that i should beable to make is the 28th of this month. I got 1130 miles on it now... and wondered if i could just top it off until the 28th or should i just hold off riding it until i get it serviced. And if i go very far over does it affect factory warranty? Oh and what oil can i top it off with since it has factory oil, if thats what you recommend?
