It´s only tornado left now i think....and kentcams but they ain´t top end power...
I got a set of kentcams wich has 248 degrees duration and 0.2 mm more lift than their YAM9 spec. so i guess they can do what you want them to...

They are out...but perhaps if one pay enough....
But then you should go for turbo or compressor and get a lot of more ponies...
Hope the Swedish TRX turbo is finished soon so we can get some numbers!!

Turbos on bikes are a crap idea - now supercharges are a completely different proposition

We´ll just have to see. (guess you mean turbos a bad idea on TRX.....)
A dude on swedish forum just made 445hp on his gixxer/busa hybrid, works a charm with turbo.
Ghostrider made almost 500 on his busa and that runs a charm.
Also, those who choose big lagging turbos (with lots and lots of power) ofter uses a nitro squirter to get the bike going from low revs. OR a valve in the plenum wich lets the bike act as a sucking engine on low revs.

I´ll probably do turbo but that´s because a rotrex is 2000€!!

Nope - I stand by the turbos on bikes are crap

what you have referred to are straight line rockets - As wise man once said "power is nothing without control!"

wot he said ^^^ its how the turbo kicks in which makes it a bad job
