I did this last summer on a 904 that are built and tied it all the way back just like TrailBeast told me to and it worked perfect. You can always give it less pressure but you can't give it more. Not enough will definitely do more damage than too much. I actually hooked a choke cable up to it so I can bury it in the cockpit but ended up just keeping it all the way out in that was perfect and ended up just tie it back and getting rid of that.
