Here's an interesting development I picked up out of Superbike Planet.

The AMA rulebook states:

"Variable-length fuel injection intake tract devices that function while the engine is operating are prohibited."

But an AMA official has been quoted as saying they are changing the rule to something like:

" In layman's terms the new rule states that if the variable intake equipment does come on the streetbike, it is legal for the class."

So Yamaha will be allowed to use the variable length intakes in Superbike.

The way they are changing the rule, Yamaha will be the only manufacturer using variable length intakes. Why don't they just eliminate the rule which banned the variable length intakes. That way Suzuki, Kawasaki and Honda could at least try to cobble something up for their superbikes while the factories work on a system for next years streetbikes, if they so choose.
