I purchased the bike not long ago and changed the coolant this week as I past my test , I pulled the pipe off the waterpump and cleaned the coolant filter out , refitted filled up and ran it to warm got all pipes warm and put the cap back on .
Went out for my first ride today did about 10miles and noticed my l9 was running at one line over running temp and no fan , stopped and noticed coolant dripping on the floor , removed rad cap and loads of air came out , topped up and got air out and went off again for about 15miles on the open road and it was fine. I got to my destination and it had another wee on the floor but the fan was going this time.
Third journey and was fine all the way home say 20miles at 70ish but in traffic temp creeped up and it wee'ed again
But its never hit the red marker
Anyone got any advise it never did this before I changed the coolant

I can't see where its coming from as panels are still on but it looks very high up possible rad cap I think
Expansion bottle is still on max mark and only minimal is being lost from rad when its getting hot
It ran fine before I changed the coolant as I had it running all the time and a friend was running it around for me
