Re: PAIR Valve mod/remove

nice thread. I have a question tho? I hit 3 deer on my k4 750 and long story short im missing the pair valve(among other things ) and wasnt planning on buying another valve if its worthless lol. So do i need to get the block of plates? or the other option would be getting the caps and just blocking it off that way right? is there any downside to removing them? I couldnt tell by the pic, but do you just put the resistor in the connector and leave it there? thanks in advance -Dave

Re: PAIR Valve mod/remove

Will a 27 ohm 5 watt resistor work??

I used a 1k ohm -1 watt resistor no problem.

Re: PAIR Valve mod/remove

Sorry to bring up an old thread, but Id like to do this to my 08 600. So I wondered if its possible to do the mod like this to it? And if it would be ok to use a 22ohm 10w resistor?

Re: PAIR Valve mod/remove

Hi guys,
I don't care much about the popping. I don't get much of it, with the m4 gp slip on and they are not too loud. But I am just curious if by capping off the "PAIR" on the engine and air box does it help in reducing the engine vibrations as well? I have a thread about my K8 600 having high freq vibrations at the clip ons and mirrors, that numbs my hands.

I have masked it by adding heavier bar end weights and I think reduced it to a minimum from 7K with the fuel mapping on the Bazzaz Zfi. Perhaps after disabling the SET valve also helped a little..(?)

Now, I primarily get the vibrations on the mirror at about 5,5K rpm which is acceptable for me, other than I couldn't differentiate if it is a cop or a taxi I see on my mirrors. The other vibration which is on my clip ons is at around 6,8K rpm. This seems to be my bike's "flat spot."

Anyway, I just wanted to give a little history of the why I am curious if this mod would reduce or eliminate the vibrations. Thanks appreciate your help.

you can just disconnect the pair vavle pipes, so no need on the resistor
Okay, just to clarify I understood this correctly. No need for a resistor if I will only cap off the 2 inlet ports on top of the engine and cap off the outlet from the airbox? Or, as I would do just put one of those small round filters at each of the 2 hoses disconnected from the engine and let the filtered air bleed into the atmosphere or cap them too.
thanks!

Re: PAIR Valve mod/remove

Cap all three ports. Two on the valve cover, one on the airbox.

Resistor is to trick the ECU into thinking the PAIR valve is still attached so it doesn't throw a fault code.

Re: PAIR Valve mod/remove

1. No, no damage to engine. The valves and ports will look like the rest covered with carbon. Make sense?
2. Reed valves can be salvaged using cover plates if you care to go thru all that work and expense.
3. If you don't care about the reeds being carbon covered or whatever, plug off the fresh air intake hose on the clean side of the air cleaner. Make sure if you stick something in that air box side, it won't be sucked into the engine or lock the throttle plate open. That, or cork both hose and the hole in the air box.
4. All parts are still connected, you just corked off the air intake and let the unit suck blanks who cares.
5. Pop is gone either way. This is the faster, cleaner way and then back to stock is remove one or two shaved cork(s).
6. Or, where are all those parts and the one that had legs and left the building and how does it go back together plan? Pass thanks.
