I noticed this morning that it came on after I had put it in gear and moved forward. Right after I moved forward.

Any pictures of these pink valves?

I'll try the soapy water thing maybe this Sunday and check for leaks. I also noticed that as soon as the whistle stops it seems like the boost kicks on. Its already there, but feels more "solid" ---if you will---. Almost like a release valve closes.
