How to set up exhaust system

​

If you change exhaust system or air clear, you will get lean mixture. So carburetor or ECU (full-computer or Sub-computer) set up are mandatory to bring out the potential spec. Without set up, you can start engine and ride motorcycle, but you feel less power in low-middle range rpm. Worst case, you can damage your engine with lean mixture.

My recommendation for comfortable, cool, easy maintenance ride:

For Air cleaner, keep stock Air cleaner box with a minimum filter and extract any obstruct in air route

For Carburetors, Install CR/FCR/TMR with Multiple Jet Nozzle tuned by YOSHIMURA.

For Fuel Injection, Install Power Commander and AUTOTUNE  (re-write ECU for de-tuned super sports).
