I received the results back from the second oil sample I have sent out on my motorcycle. The bike is a (Chinese) 2020 CSC RX4. Engine break in was conventional oil. I swapped to full synthetic after collecting the first sample. The second sample was in engine for 3,500 miles not 35000 (lab typo). Both samples show lower viscosity ratings than expected. 10w40 should be 14.5 cST new (according to the Valvoline SDS). The second sample shows elevated aluminum wear particles in suspension. Both oil screens were clean as well as the filter when I collected the sample. Sample was collected warm and mid stream as the last one. I'm unsure what baseline aluminum levels should be for a liquid cooled high reving thumper. I believe the cylinder walls are plated/coated. Maybe the aluminum is from clutch basket wear? Valves have been checked recently and were fine. Any thoughts?
