I have bought a WR 450f 2008 model, great conditions been running great since i have it.. but i have a few questions that i need help with. this might sound like a really dumb question but here goes..... Under the seat i have a 'coolant' pot, which has decided to start emptying it-self on my last ride out, is this normal or i might of not noticed this before. Whats the main purpose of this pot as i keep checking my Radiator and its full all the time and i believe theres a pipe going from the rad at the top into this pot under the seat... so I'm just wondering is it an overflow pot that doesn't need to be topped up or do i have a slight problem i need to fix. But... The main reason i ask is, i also have a slight leak from a little hole on the water pump that i believe (i might of researched wrong) a weep hole? (ill also attach a picture) So i dont know if I'm loosing water, burning it off somewhere, have a seal gone in the pump etc... Just after some advice please as I'm new to the WR scene and i dont want to cause any problems in the engine Thanks everyone!!
