Mine was similar but, I could attribute the low pressure to oil temperature from the riding I had just been doing (lots of throttle and heavy loads).. I don't have an oil temp gauge but, I just know that the oil was hot LoL!! I'd go with the cooler and if you got problems still.. I'd say it might be in the oil bypass for you.. If so, it's in the oil pump assembly on a chery engine! But, lets hope not!! LMAO
