Misfire

[grog]

Andre, i now agree, block vac hose takes load off valve, will do that. Quiets throttle body? Not sure what you mean.

[Andre]

Was a little lazy there Grog and put parenthesis around "quiet" to avoid explaining
Change in the negative pressure in the TB is slightly reduced/delayed by the available volume of the hose and the air cut valve up to the diaphragm.  I am all for minutiae when it comes to setting up my bike.

I might need that air cut valve functioning in the future (Mot emission testing), so I want it to function again when time comes.

If it weren't for MOT and prying eyes during controls (they started to do big controls with cops, MOT-techs, and registration officials) I would just throw all the PAIR stuff out - BEST solution.

[grog]

i probably should take it all out but no reason, bike running just perfect, dont like fixing what is not broken. yeah, being a virgo im very fussy also. just how it is. slightest noise/vibration etc just wrecks my head. i always have a head full of bike/car/golf/work/house things to improve. golf is the hardest.

Andre... I completely removed the pairs system some years ago and not had any issue with emissions tests so far.. including roadside tests by the powers that be here in Austria.   Not sure if German testers are any stricter....

[Andre]

ARH, the emission test for bikes here is a joke. All they test for is CO. You fail if above 4.5 (for 14 without cat, the others I don't know). You got to have a serious issue to fail this test. A defunct PAIR shouldn't cause a failed emission test. I'll find out next MOT for sure

However, there is a small chance that you meet someone that is knowledgeable and takes a look. At MOT no big deal. Get the PAIR back in and they check it off at second visit. Still, I don't want to go in for a 2nd visit.

If cops are involved it looks different. I am not keen to find out regardless of how small the possibility that someone will actually look. Plenty of people here who ride with PAIR uninstalled. Haven't heard of one getting caught. This paranoid forum member will not be the 1st.

Luckily in the uk emissions are not tested for our m.o.t's here.

I understand what you mean Andre... but I reckon the cops would really need to know what they were looking for to spot that a pairs system had been removed.... even more so info the components were still in place but 'blanked' off as some have done here. 
I previously asked the guy who does my mot (top bloke who was rated top mechanic in EU by Suzuki a few years ago!) who is pretty stringent with the test but said that the pairs setup was a bit of a joke.... he was happy I'd removed it 

[Andre]

I do know some cops who know. I doubt they care to take an "official look" unless you behave like an ass. With all the components in place there is no worry at all.

And yes, the system is a bit of a joke.

@seth... we even have noise levels checked with a dB meter... 

[seth]

God no not here it's down to the tester if they think it's to loud .
My akraprovic is ok my cut down Stubby is a no no .

[Hooli]

My tester runs ducatis with open cans, nothing is too loud

Austrian registered bikes must conform to the vin plate... from memory that's 84db at 3200 rpm for the 14... so no chance of using loud cans....

[Cykik]

M2 Buell with "open" V&H can used to pass  mot every year!!

I recall someone on the old Org remaking their VIN plate to match their new exhaust....
