i did the same thing on my 84 cr125... didnt know the water pump was rotted out on the inside, leaked all the coolant into the motor and i was flyin threw a field wide open top of 5th and the motor locked tight and locked the rear wheel, thank god for quick thinkin and i pulled the clutch in and stopped
haha it feels like it rips. i get flung all over the seat haha lets just say forearms burn after i ride and its pretty much stock but hopefully not for long
