Hey Hargray2 - Go Yamaha!
Dual overhead cams, and revs to 12,000rpm
I landed on top of someone in practice when I first started racing. It was the biggest double on the track, and he slowed down after he landed instead of pinning it. I yelled "HOLY S**T" - he looked up/back at me and his eyes almost bulged out of his goggles. Someone else piled on too - it was a goon yard sale! We were all OK, but I had a killer charlie horse that changed colors for a week.
