| First of all, I was told that modding the valve doesn't get rid of the 'honk', instead they told me it needed to be lubricated. So, today I bought some valvoline grease with white lithium based stuff in it. I applied to to the whole underside of the diaphram, and my valve still honks. Any suggestions? |

| Are you getting good shots or wimpy shots? |

It's hard to say, this is my first pneumatic, so I don't really know what a 'good' shot is. But in my opinion I think its a little wimpy.
Edit: I was trying the lubricant because I would be happy if the cannon didn't make such a loud noise, and so that I wouldn't need to make the pilot valve larger ($$). |

Bump...
Has anyone here stopped the honk on a rainbird? If so, please inform me how you did it.... |

I've read a few different reasons in hear for why valve's honk. I think the most logical is that after the projectile leaves the barrel, there is still low amounts of pressure leeving the chambers through through the valve, vibrating the diaphram makeing the honk noise, (in my own words).
Difference whimpy shots, and strong shots -- a strong shot will have some recoil and make a fairly loud pop sound, (probly 30psi and over). A whimpy shot will sound like a fart leeving the barrel, (with no cheek flap).
Maby some valves will just honk no matter what! One more thought, is there a bleeder flip swith, if so make sure it's off. Hope this helps. |

| I thought the honk came because air is still in the pilot and chambers and the diaphrahm vibrates between them. You could fix this problem by modding the valve, or if it is already modded, use a shorter section of hose or use a better valve then a blowgun. |

Squeaks is echoing the post just above his, (mine), except the hose part, good add on.
The spring probly helps hold it still, if there is one in there. |

| Well, I was saying, or rather attempting to say, that the honk actually means the valve isn't opening completely because there is still air behind. Therefor, remove the honk, valve works better(for those of us that didn't know that already). |

| Hmmm, I think I may have to modify it after all then. The valve has a plastic bleed screw, so I should make sure that it is as tight as I can make it? |

| The valve isn't honking because it isn't lubercated! You need a bigger pilot valve. Try modding the valve that solves the problem. |

| It was just I read somewhere else that the diaphram was meant to be lubricated by the water which helps it sit back in place... |

| The lubricating doesn't really matter with a diaphrahm. It's when you have o-rings on a piston that you have to lubricate things. |

| the flow control valve should be opened as much as possible, that limits diaphragm travel which could help with the honking. Modifying this valve is easy through the flow control screw hole, there is a No Drill mod tutorial on this site for that model. |
