I absolutely love the exhaust note, & will probably "borrow" the fuel shut off idea as well...Nicely done that 👍

Hello
Thank you for your good comments
Just a piece of information.
With the fuel valve, there is a fear of an air bubble remaining in the pipe, if there is an air bubble, the engine does not work well.
