I'm going to be taking the PAIR valve off soonish & wondered if anyone had any recommendations on Blanking Kits.  Moccs seems to be the favoured choice - anyone had any first-hand experience of that one or any others?

Cheers

Hi Dave,

I scrapped the pair valve and all the other bits 6 months ago due to a weird throaty flappity farting noise on deceleration and suspected a faulty valve. I made my blanking plates out of 4mm stainless using the originals as a template and used a thin lick of high temp red silicone to assist in the seal, I then reused the original bolts. I brought a 4.7k ohm resistor and made a connector out of single pin connectors soldered onto either end of the resistor and with some heatshrink, bending and fine judgement, that plugs into the location where the valve used to. This fools the processor to think the valve is still in place. Many 800 owners cut the original connector off the pair valve setup and simply use that to solder the resistor to.

The front bolts are a right pain in the backside to remove and put back, but apart from that it works a treat. If your a handyman, they can be manufactured easily. Total cost $5NZ dollars and an afternoon in the garage listening to the radio and drinking beer.

Thanks - reckon I can probably do that, or know someone that can knock up some plates for me.  I must admit that in my naivety, I assumed that I wouldn't need to do the resistor bit - I thought that would only be the case on bikes fitted with injection, not carbs.  Is it obvious where the resistor needs to go?

Oops... sorry dave, you got carbs... should have taken more notice. Google it for your model. Mines a 2009 with fuel injection. If i dont have the resistor the FI light will remain on as a warning.

Just had a look on Google. Go to this http://www.moccsplace.com/images/pair/pairvol.htm web page and have a read. It does not mention anything about the resistor I had to place on mine. It must be vacuume operated.

Yep - that's the same page I'd read.  Thanks for settling my mind at rest .  For what the kit costs, it'd be far less time consuming to just order one straight off him.  

Thanks for your help

Thanks Captain Crash - I'm going to disable the valve first, to see if it has any detrimental affect.  As long as there's no negative reaction, the whole thing comes off.  Apart from removing an ugly looking piece of metal from the jugs, I'm hoping it reduces the vicious backfire.  I have straight-thru pipes & I'm guessing the valve intensifies the backfire 

Thanks for your input

Hi guys.
Simple question ok? What benefits are there to removing the Pair system as I'm new to the VL800(C800) engine.

Simply put it takes away the popping and gurgle on desecration. Some hate it, I love it, each to their own.

No worries Peter & thanks, It becomes more noticeable with some aftermarket exhausts.

Yeh I'm leaving mine alone till I really need to change them Dave as I quite like the 'silent approach' that mine has at the moment. When I finish re-building my Velocette then I'll be hearing a real exhaust note again!

Decided to disable the PAIR valve after work today - took about fifteen minutes, ten of which was finding something to plug the air lines.  Result - end of backfire completely.  Now, I have no problem at all with a bit of tasty backfire on over-run, the Katana sounded the dogs, hand built 4-2 with Laser sports cans - I loved it.  However, with straight-thru pipes, the VL sounded like it was going to self destruct.  Seriously, it sounded like a shotgun going off & as I sometimes go to work at 05.15 & sometimes arrive home after midnight, weekends included, I wasn't making neighbourhood friends.  It was also bound to attract unwanted plod attention, which frankly, I don't need.  So disabling it was ultimately the cheapest option.  

I have to say, it was the cheapest, most immediate gratification I've had in a long time !!!


It now sounds meaty without being over the top.  Next task is to remove the valve completely & display the jugs in their naked glory.  Now that a bit trickier, so if anyone in the Notts, Derby area has already done it, I'll gladly feed you coffee & biscuits if you come & give me a bit of moral support on the spanners.

Have a long reach 8mm open ended ring spanner handy. Find someone mechanically minded with long skinny fingers to assist with the front blanking plate (That ones a b'strd to do so read about some of those other bits that can be moved on that web page to assist access. At the end of the day it's really worth it. I'd gladly assist but I really hate long haul flights.
