When I bought my FZ1N it had a Scorpion can on and the previous owner had disconnected the ex/up valve leaving the cables taped up under the seat.I don't know if he did any mods to the bike but it runs great,perhaps the only thing I could say is that it pops on the overrun which is ok with me anyway. :lol
The fzs1000 gen1 needs the exup in place to run correctly, the FZ1 gen2 does not.
On the FZ1 it is just for emissions and does not seem to affect the running at all, just about every FZ1 with an aftermarket can has no exup fitted.
If the popping on the overrun does start to bother you just disconnect the ais and block it off

:o Just read this,sorry but at least now I know,thanks, :thumbup
never look down on anyone unless you're helping them up.
I apparently had no EXUP valve in my last one. It was a pain at low revs, traffic speeds. I tried going back to a standard can, tried another 'performance' can. Made little difference. I didn't even know it didn't have the valve, so I thought it might be a carb problem. Had the carbs removed and cleaned, checked over. Nope. Then got it full monty Ivanised. This made a considerable improvement, and I was happy enough.
When that bike got replaced with my current one, it was only then I realised what had been missing with the low down grunt and smooth pull at low revs, although this one has had the Ivan's from the start. And this despite having owned 3 others before that. I can be such a numpty at times :rolleyes

Trust me, we all make daft mistakes nick. Its the ones you make when you damage summat (often irreparably) that hurt the most lol. Last time I changed my van (traded my 214k sprinter in for a 09 transit with 88k back in 2014) I was so enamoured of having a "new" (to me) van, I didn't feel I needed to check the oil for the first few months When I finally did it was off the dipstick. I wanted to cry, paid eight grand I could ill affored for that van and didn't check the frigging oil...Still got it and it has 170k up now so I didn't kill it, but i'll never know how much damage my negligence actually did.
I used to do a lot more work on my own bikes Paul, but now I give myself less opportunity to foc up :lol
My brother once did a corker - replaced the sump pan on his Z650 for 'reasons', but forgot, or probably didn't know that he needed to take the oil pressure relief valve out of the old one and put it in the new one. Then ran the bike, despite the oil pressure warning light glaring at him accusingly. Much damage done! :eek
EXUP valves, fortunately, are not on that scale of risk :lol
I am now racing a 2004 R1 which appears to have an intact thingy, ummm, exup valve, so some learning for me,, a winter job will be to check it's free movement

Had major problems with the bike, was fully ivanised over 10 years ago and was getting around 95 miles before light came on and other gear changing problems so decided to take the whole thing back to stock,
New carbs, oem air filter etc, Someone decided to play around with the carbs and air fuel settings were between 6 half turns to 7 three quarters!
Next job was to sort my exup out, all the bolts on the valve were seized and rounded, i managed to take whole exhaust off including Radiator, the exup pulley at valve disintegrated also the cables were frayed to 50%,
Headers were horrendously corroded at the manifold so costed it all up to replace and went with Black widow headers and delkevic link pipe and can,
Took all the cables up to the servo out and cleaned servo leaving it attached,
Result????
Well happy with the result, been out twice and a hardly noticeable change between 3k to 4k at all and sounds a lot better too, Looks good also and with my new Fazer Rad cover lol...
No more Exup woes for me or paranoia any more, a mate of mine with a same year fazer has ridden it today and really liked the different character the bike now has, Power too!
I believe after tonnes of research that if you have a modified bike then this wont work for you, these Black widow headers are only designed for stock bikes only,
I do hope that this helps anyone :rollin

This is interesting, before I decided to sell my Fazer (after buying a new bike) I was considering this option but I couldn't find any legit reviews on the headers. My bike hasn't been ivanised and the exup valve has been pinned open since well before I owned it (nobody told me). The only thing I notice is slight 'hunting' around 3k but otherwise the bike is very smooth with a good power delivery. If I keep the bike then this is an option I might visit.
When I bought my bike the valve was stuck, I was going to the south of france when the 7k error code showed up. No time to sort it. I didn't notice any problems. Must have been stuck in the closed position I spos, fixed now . I got a new / second hand valve and cover. I think in normal use you can get away with it, nice to have stuff working right though.
