jh yes your wright its well covered by patent but you would reckoned that some wiz kid lawyer could get around this promlem ,or maybe Honda/Yamaha have got a pride issue

Yamaha don't have any pride, they finally dropped their 5 valves per cylinder ie, 20 valve head the other year, but not before they'd sold the technology on to a few other manufacturers. Although no one else has been using anything other than 4 valves per cylinder for years now in racing!
Aren't the HRC Repsol bikes running pneumatic valves for this season? but not the customer bikes!
Yamaha tried pneumatic valves last year, but it exposed vulnerabilities in the bottom end of their engine, they better get that sorted first!
I suspect we'll be seeing all pneumatic valve engines by 2009, except the Desmo's!

Zydon, I see your point too. Most of those circuit has fast dropping level and stop-n-go types. I noticed that this kind of circuit were not favor to Rossi.

Maybe Vale struggles with the front end????
