Hi, I'm new to trials bikes as I race quads, me and a few friends have purchased trials bike for over the winter to play around the farm on, I just purchased a 2003 beta rev 3 270 and need to no how much oil to mix with 5 litres of fuel? Also if there is a certain oil I should stick to as it's going to be my first outing this weekend, so all tips or advice is much appreciated!
Thanks
