Last season I bought a 1996 polaris Indy xlt 600 triple with no modifications. I had a bad water pump right off the bat and then when I replaced it I went for a ride and the temp light came on after 5 minutes. I opened the hood to no coolant so then I replaced all the lines, it held a little bit and didn't overheat but was obviously leaking somewhere. I replaced all the top end gaskets and it seems to still leak a little bit but it is much less. The radiators are good, no holes, dents or anything they seem to be perfect. I also pulled the motor to see if the head was cracked and it was fine. Does anyone have an idea of what could be going on?
