1) Pull the tank offhow to drain coolant from radiator on m109?
Very easy to do. Some advice...while you do it, check all hose clamps. Behind the resevoir, on the clutch lever side of the bike you will see 3 hoses come together in a "T". That is the culprit for most of the antifreeze leaks. The bottom one tends to come loose. I just did my antifreeze about a month ago as I had a leak and it was time. I pulled most hoses, cleaned the inside and the fittings and put back on and tightened down. No issues now.thanks will try and do it myself.
