I have a 2019 Grom with a Takegawa 143 BBK and cam, SUP oil pump, Kitaco clutch cover, Yosh complete exhaust, Dingerbuilt short intake, and a PCV with WBC2 installed. Whilst driving down the road at WFO throttle and redline, the motor start making a knocking noise then quit moments later. The piston is roasted and the cylinder walls are torched. I have installed a new 181BBK with oil cooler. While the engine was apart, I inspected all the accessible oil ports, oil pump, filter and found a bit of what appears to be grey gasket material in the filter and screen. I was wondering if there is a blocked oil line. Is there an oil jet that sprays the bottom of the piston or is the piston oiled solely by the splashing action of the rotating crank? Does anyone have any ideas? See attached pics.
