Cheers Matt. Great link!!

PS MAtt I don't suppose you can shed some light to the fact that my Yamaha engineer and many others insist that the 2-strokes VMaxes the 200 and the 150TRP (not HPDI) produce the 200VMax, 230bhp and the 150VMax, 170bhp. Something to do with this VMax technology which kicks in after 4000rpm.

Is this correct?
