    Drained the coolant from the bike and I have only managed to get around 1.5 litres into the bike. I have just taken out the bleed screw from the water pump and nothing is draining out. What am I doing wrong?

    I cannot upload the manual, only the coolant section is already 16,3Mb.

    You can reach the lowest coolant hose on the left side of your bike near the footpeg, sqeeze the hose hard a few times with the coolant cap off.
    Start the engine and wait until coolant bubbles out. Close cap.
    All air will be pressed out, and problem will be fixed.

    I'm not sure you are doing anything wrong. I drained, flushed and replaced my coolant recently, following the procedure in the workshop manual and I got about 2 litres out via the drain plug. I flushed with a flushing agent, then a few rinse outs with tap water and then drained completely, squeezing hoses to get every last drop out. I got just over 2 litres out on the last drain. When I filled up, I got 2.2 litres of coolant in it after a few run/cool/top-up cycles and that included topping up the expansion tank. My only conclusion is that there's a misprint in the manual, looking at the schematic, there's no way there's almost 2 litres of water in there that can't be removed by draining. When I completed the procedure I ran the bike through two fan on/off cycles and it needed no further top-ups. My TDM900 takes 1.75 litres of coolant for comparison, almost 4 litres seems an awful lot for a motorcycle.
