Not at the moment i needed it...after the break in...they are not used to it beacuse it's new. Everyone thought it was the same of the old one that is the same from my06
The bypass valve is spring loaded inside the filter. Depending on what the pressure is, it could very well activate with the higher pressure under normal conditions. And it's more about the filter element getting blown out from the increased pressure and causing debris or clogging the filter itself.Bypass valve works when the filter is dirty and the oil can't pass through the filter properly. So I guess that could be the problem. But with fresh oil it should be ok
yes, this is what I think tooSo basically, change your oil regularly (which we all do anyway) and we'll never have to worry about a bypass valve needing to open in the event oil cannot pass through the filter any longer. I suppose in the event if some other, unknown issue where the filter gets clogged, then that would suck!
That would totally defeat the purpose of the new filter. Kawi increased the oil pressure to help support the crank and rod bearings and prevent them from spinning. Among other changes to the crank for this, increasing the oil pressure was one way to do that.The valve opens when the pressure gains (for many reasons, for explame the filter is full) otherwise it stays closed. When it opens the filter doesn't work anymore and the oil is no more filtered. I think the new filter has a different spring that opens at a lower pressure
are you sure they increased ?That would totally defeat the purpose of the new filter. Kawi increased the oil pressure to help support the crank and rod bearings and prevent them from spinning. Among other changes to the crank for this, increasing the oil pressure was one way to do that.
So having the bypass valve open at lower pressure would make it activate sooner, bypassing the filter element. No, the new filter element material, or pleating, or support material was most likely changed to prevent the element from coming apart or failing under the higher pressure and to keep the bypass valve closed until it's actually needed. Obviously, the oil pressure is highest at high RPMs under racing conditions, but there's probably a bit of concern if running the motor with high oil pressure on the older filter.
Clearly, the engineers at Kawasaki felt it necessary to change the oil filter design to handle the differences or they would've reused the G4 filter design.
are you sure they increased ?
From what I read on the manual they decrease oil pressure
that is 0.92 kgf/cm², @4 000 on the 2016
and 1.5-2,4 on the G4
almost the half
Ahhh, but the readings are not taken at the same temperatures. The Gen 4 is recorded at 50 deg C and the Gen 5 is taken at 90 deg C. That's a significant difference in temps that will change the readings based on the viscosity of the oil. So it's not really a straight comparison. It doesn't account for the large drop in readings, but still.Here it is
