I have a zr 400 xanthus here, i filled my coolant reserve up to 1/2 of its tank. Cant really see the lines marked as to where it is on the maximum. While Im using the bike the temp goes up half of the gauge together with the fan running. I dont consider the bike as overheating already but how come collant comes out of the reservoir? It sorts of flowing out and when the flow stops I think that collant is on the very low side already short of dried up. Not experiencing overheating but am a little bit concenred on the amount of collant and water. Should I change my radiator caps? Are automotive caps be used on my radiator? What exactly is the number of pressure of the cap would i get? Will I go for the higher or lower pressure caps? TIA guys.
