@locusthillclassics: 1977 Yamaha TT500 with megacycle cam and springs, Wiseco piston and Mikuni carb. I use this bike for vintage motocross and flat track. I have suspension and wheels for both. #yamaha #dyno #motorcycle #motocross #vmx
Love these dynojet videos putting people in check on their crazy claimed hp numbers

I love these I like to guess how much horsepower it’s making by the sound of the motor. I’ve been pretty damn close each time.
