well i had a incident once, while riding on 5th gear doing 75mph and I somehow downshifted to 1st gear. check engine light came on, oil light started blinking. and even after that. it showed now signs of damage. few weeks later drove it from ATL to WIsconsin. and it just seemed like it wanted to give up like it got weak. So i replaced it with my spare motor. And found out my OIL pump gave up! 8D
