I ride at high altitude and have seen on other threads that it is best to have the red RAVE screw cap adjusted out so that it is flush with the black housing. I did this today and it looks like there is an o-ring just hanging out in there. Also it seemedlike it would now turn easy enough to just vibrate loose when the engine is running. Has anyone else experienced this??? Any problems, resolutions, or just let her go and see how it does?? Any input is appreciated. Thanks guys.
