My Ninja H2 has ‘miss’ at high RPM’s

Original Question: My Ninja H2 has ‘miss’ at high RPM’s. It’s running great, but then just falls on it’s face. My mechanic can’t find anything wrong. It’s driving me crazy… what could it be?

Sounds like a boost leak as pressure increases with RPM. The most common spot on the H2’s seems to be at the clamps which secures the orange hose between the plenum and supercharger. Many times, simply tightening the hose clamps cures the problem. Otherwise, check all clamps and connections relevant to pressure/boost.
