Allright ladies and gents. Help a girl out. Questions below. I have answers, not sure they are correct, except I'm 99% sure about the first one since I read it on superbikeplanet.com.

1. What bike did Dave Sadowski ride when he won the 200? Who sponsored said bike? {Answer: Vance and Hines sponsored his Yammi FZR750RR}

2. Who was the first American to win a GP?

3. Who was the first American to win a World Championship title?

I've got answers for 2 and 3, but I'm not at all confident they are right....
