How much oil per 5 litres of petrol should I use? I'm all new to trials bikes but a friend recommend 3% oil to petrol.
The bike was empty of fuel from being out on it yesterday so I filled it up with the 3% mix this morning but I soon found the bike very stuttery - e.g. in 1st gear on level ground with the clutch fully out the bike almost wanted to stall. The tip of the exhaust was also very oily.
Is this a sign of too much oil? Would 2% be a better mix?
