Thanks Lyoko. Can I open the radiator cap. I know the manual says not to do that. Sorry I'm new to all this. How can I see if the bike needs coolant in the radiator? Should I put it directly in the radiator or in the reserve tank through the cap on the left side bottom?
EDIT: Also, do you see blue coolant in your reserve tank?
Yes, there is no problem opening it. Just make sure the bike is cold, so that there isn't any pressure inside the radiator due to heat.
There is a little safety screw on the radiator cap thou, have to screw it a little out to twist the cap.
Basically, if you fluids inside the radiator when removing the cap, it's fine. If you however don't see any fluids inside it, then that's bad.
Always fill fluids into/through the reserve tank, never diretly into the radiator itself. Fill it until you reach the maximum line.
Guess it's a "long time coming" since I've checked over things on the bike. I'm heading out soon, so I'll take a look, refreshen my memorie in regards of this, and get back to you with more sertant answers here.
