Once rode my fj1100 up a 2 by 12 wooden ramp into the back of my 4 wheel drive super duty ramp was so long that I had blocks supporting the middle so it didn't sag. Slowed down at the top so I would not crash into truck and tried to put my foot down. One problem I was still on the ramp. Foot just found air goosed the throttle spun the tire and made it. I'll never try that again. Scared the crap out of me.
