Coolant on the left side of my engine case last night...

[Rocket Scientist]

+1, usually on a cold morning.

Mine will loose several drops somewhere near the thermostat housing when it sits for the winter. I just stuff a sock in that area to keep it off the paint. My ex had a CX650 Honda that did the same thing. I don't sweat the small stuff

Mine doesn't like to have the overflow "full" as Triumph says to. When I have tried to fill it to their level, she pukes a little until she finds her own happy level in the overflow box.

Exactly this, when it comes back from the mechanic it's always "full", which in reality, is a touch over filled and spits a little dribble or two.

The overflow bottle should not be filled above the minimum mark when cold, or it will expand and overflow from the spill tube. Check the hose connections also.

Hey Hobo I had a small crack on the neck of the radiator funnel where the cap goes. Noticed coolant on the block 2 days after purchasing an 08 rocket, every time I turned the bike off after a ride there was coolant all over the front of the block on the left side of the motor, replaced the radiator cap but still found coolant, found the crack and used a putty called Needit and haven't had a leak since . Hope this might help .
