Radiator over flow.

Hello Ya'll,

I am having a problem. My bike runs normally temperature wise but the radiator keeps on venting fluid. I have the Trailtech vapor so I can monitor the temp. When I get home after a ride the coolant is low in the radiators. When I crack the cap to check the fluids I here a vacuum break. The Evans NPG+ seems to expand out of the radiator but it does not return like it should. I am running the SRC thermostat and the stock radiator cap. Do you think it is the cap? Thanks for the help. Tony

Hello Ya'll,

I found the problem. I recently replaced the water pump. I looked at the pump and the area where it seals to the case is leaking. I am going to get another o-ring for it. Hopefully that will help the problem. Thanks for the help, Tony
