Basically if you modify the bike - example - performance headers, performance end can, performance air filter etc your fuelling will be out. As such your bike is not making as much power as it could (+ likely to be running very lean).

Dyno runs can show you the power, torque and fuel curves. From this data the operator can tweek your carbs.

I think I paid £45 for a dyno run at RJS Superbikes. That's without them messing about with the carbs which could have run up to a few hundred quid.

It can also be used to show you the overall power but remember one dyno will measure different to another!
