Pes,
My best friend Phil, a gearhead M.D.(that's how he can afford to have a garage full of classic bikes), has a pristine example of the old Yamaha H2 750 Triple(I think his is a '74).
I took it for a ride a few months back, and I had forgotten that that sucker's powerband(typical of 2-strokes), as you roll on the throtle is...well...nothing....nothing....HOLY CRAP! HOLD ON!
