    450F Is my oil pump bad? Yz450F

    Its a short video, not spam or anything weird. Someone please check out and let me know. As I stated in video, with oil pump in my hand, it turns smoothly, no issues. Once I tighten to 2 bolts down, it begins to show some resistances, even without/before I put that other gear on that interlocks...
