Hi I’m still a few weeks from starting my bike .. but after draining all oil out bike I’m wondering the type to refill in Uk ? And how too? Far as I can see there’s the top tank under petrol , gearbox oil with a dipstick, primary side with a nut you extract to see level , and the other side with the oil return pipes to. So where do I fill them all too and levels ? Can’t find any literature re this ..
