October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Anti-Afterburning Valve (AAV)

Hold a piece of paper under the AAV, run engine to 3000 RPM and close the throttle quickly. If paper is sucked to the AAV at this moment, the AAV is operating normally. If not, the AAV is defective. Replacement is necessary.
