Did you know ST4 systems give a big performance increase.

Can't quite see where you get that from Paul The page seems to say that a std ST4 header gets you there. There is alot of info there, and a header is a fairly complicated thing. They use pulse wave reasonace to create back pressure, to effectivly supercharge the next fuel charge in the cycle. (Cam duration becomes critical to this effect.) And so on it goes. blah blah blah. The up shot of it all is that there is a point where you have to decide how much life you want your crank cases to have. More HP and torque, less engine life. At the top end a race engine is good for max 1200hrs, and I believe ducati bin each set of cases at 600hrs. So all the big valves, port and polishes cam timeing and compression increases add up to more engine rebuilds. A happy medium has to be reached.

Both Bevan and Mr personality know this and both have other engines at there disposal, so they can afford to **** about.

Sorry Rob I was only interested in the price.
