Double stack- hold the cheese

I am very excited for these.

They will derestrict our TB from the 26mm they are choked at- to allow the full 32mm - and then the new double stack improves airflow beyond the factory single design.

Even on Honda bikes that use the same 32mm TB as our bike- with 32mm stacks from the factory.

The CBR 650 uses the same 32mm TB as our bike- with full 32mm stacks from the factory- on an engine almost half the size.

Going to a double stack design on a stock CBR 650, just swapped in without touching fueling- gained 3whp and no losses.

I’m thinking we may approach closer to 110whp once I get these in.
