I love my fazer to bits, and think it's possibly, no, definitely, the best all rounder ever built. But that bloody exup.......anyhoo, today the missus has an eye test in the heart of Bristol. Living in the Forest of Dean and Knowing the traffic will be horrendous from the Severn bridge onwards I take her in on the thou, with its freshly greased exup valve. In Chepstow I get the bloody 7k fault! Anyhoo, it was intermittent so onwards to Bristol, and I park on the pavement and get the toolkit out right outside the opticians. At least I can play the breakdown card if a traffic warden shows up. By now the fault is happening constantly, and it's ok in the city so I know the valve is stuck in the closed position. I whip the pulley of the valve and try it, valve turns easily and smoothly, so put it back on and slacken the cables a bit, reasoning that I've over tightened them perhaps, even though it's done probably 200 miles since I last adjusted them. No difference, so I take the pulley off again and check to see if it moves around hanging loose. It doesn't, both when I'm revving the bike and when I kill it with the kill switch. So all back together, and head home with 7k fault going all the way, and get there wit h about an hours daylight left to check it out. Again pulley off and check, no movement. So tank up, left hand infill and fitting bracket ( the one with the reg/rec fitted to it) removed to give me a bit of access. I'm thinking the cables are frayed internally and locking up, but pulling on them near the servo pulley with needle nosed pliers they seem ok. I pull them back up through the outer sleeve to give them both an inch of play near the servo and try it again. Servo not working! Wasn't expecting that :-( anyhoo, there's a slot in the left hand side of the servo pulley, I can just about reach thru with a slotted screwdriver and put it in the slot and see if there's any movement in the pulley. It's stuck but suddenly gives a little bit. I start the bike and bingo, it's turning ok, and no 7k fault. I spray loads of wd40 into the servo pulley shaft as best I can, reconnect the pulley on the valve, and take up the slack in the cables, and try it again. It's all working ok. Buggered if I know...I've not used the bike for a couple weeks while I've been away working, is it conceivable it seized up in that time. Have sprayed loads more wd40 around the servo pulley and will give it 20 or 30 miles in the morning to see if it's behaving... :rolleyes
-
Despite the problem, it does remind me of another reason I love this bike. It's dead easy to work on generally, and having replaced a lot of bolts for stainless cap heads the standard tool kit and a decent set of Allen keys under the seat means you can tackle a lot of the jobs at the side of the road. I think the only real fault gen ones have is age catching up with them. Annoyingly I never owned one from new; I did test ride one when they first came out but they were such ridiculous money new I stuck with the hayabusa I had at the time :-(
-
Think I'll start shopping around breakers for a spare servo motor, Is it a bugger to change? Looks fairly tight in there... :'(
-
ive got a spare mate, cheaper than evilbay too!!! PM me
-
That's awesome mate! I'll pm you now :-)
-
Went down to Chepstow and back this morning (25 miles) and it behaved, but I think I'll change it anyhoo and get the old one checked out see if I can keep it as a spare
-
After lots of similar problems to you I finally bit the bullet a week ago and disconnected the exup cables and replaced the exup valve locked in the open position. Was expecting a big drop in low down responsiveness after reading up on it but it's barely noticeable - think there's a slight delay when suddenly opening the throttle below 3k but that's it. Wish I'd done it ages ago!
-
Btw perhaps the trade off is less noticeable for me as I put the exup back in rather than removing it completely as others appear to have done. And the valve probably wasn't working to it's optimum before even when I wasn't getting the 7000rpm fault code as it had stiffness in the movement.
-
Exup ??/ you can take them off on gen 1s and never know the difference,,,don't knock it if you have not tried it. :D
-
"Don't knock it if you have not tried it. :D "
Next thing you'll know will be something about sheep herding............. Nothing whatsoever to do with your EXUP :lol :lol :lol
-
I know and rode many times with a member on here who has a Gen 1, he loved that bike , thought it was brill,bike went real well,never gave any problems,,one day upon inspecting the Exup he found that there was no valve in there and had never been since he owned the bike,,,,makes you wonder doesn't it :rolleyes

Earlier this year I was hit from behind by a car when the drivers foot slipped off the clutch at a junction... The impact bent my exhaust forward, I didn't realize at the time but after straightening/welding it back up it had broken the low mount and snapped both exup cables. As it is my daily hack/commuter I rode it unwittingly with the exup loose and the bike was not the same, it would struggle to go over 80 and slow to get there. After seeing the cables snapped I ordered new inners from venhil and wired it open in the meantime. The top speed was back to normal and if riding it with any vigor (ie keeping it above 5k or so) you wouldn't really notice a difference. I did notice it when commuting however, less low power, not as quick when filtering/nipping around etc. Fitting the new inners the bike does feel a lot better, the exup definitely makes a marked difference to the performance when everyday riding.

Still useing the old servo motor as it's been ok but this morning valve was Clanky as buggery and exup fault came up then it suddenly went quiet after three minutes running and fault stopped showing on tachometer, been ok since. I'm guessing cables need adjusting?
-
easy check just take cover off ??? :'(
-
The valve itself is fine mate guess I gotta bite the bullet and change the servo motor, was hoping to get away with keeping it as a spare :-)
-
Gonna change the servo motor this weekend, looks like it's gonna be a fiddly bugger. Gonna check me carb needles while I'm at it see if it's been ivanised..
-
Hope you've got a nice warm garage, :) I gave up working out in mine today.

Had a similar issue a few years ago. Exup valve free as a bird, cables looked fine but changed them for slinky glide ones. Intermittent 7K on the tacho. In the end I bought a second hand servo and fitted it, no more 7K on the Tacho. :woot
I noticed the pulley on the old servo was much harder to turn than it was in the replacement.
Dismantled it and cleaned it up, everything moving freely. Reassembled it still the same.
Pulley would move freely when disassembled, but not when assembled.
Took it apart a few times, but could find absolutely nothing wrong anywhere on the gear system. :rolleyes
I even tested the motor and it was spinning freely. Totally baffled, I put it in a box in the garage and it is still there :lol
I have the AIS removed which made replacing the EXUP Servo easier.
Take pictures of the way things are routed and how they are located before you dismantle anything.
-
I have removed the AIS, and going to change the cables in my exup, do you think i would be better to remove the servo to fit cables or try and fit in place?
-
It is easier with the servo off, but do not remove it from its location, rotate the unit to make fitting the cables easier and then put it back on. It
Take note of which cable is which and how they are routed to make replacement easier. Servo is easy to take off by slipping the rubber off the mount instead of undoing the mounting bolts.

Cheers mate pics are a good idea. Been laying stone today will give it a go tomorrow, be interesting to see if my problems is the same as what happened to you. It seems to work intermittently, though mike did tell me it doesn't take a lot of resistance anywhere in the system for it to register the fault and essentially put the servo in safe mode. I havnt got a warm garage I've got a cold container....:-(

Oh wow, that must be cold in there. The very best of luck :) .

Cold in there FFS it's a monster walk in freezer in this this weather, and non fan assisted oven in the summer with the sun on it.
My mate Dazzer (Darron) has one and its so cold in there, we left a bottle of coke in there the other day/night and by morning it was mahoosive coke lolly.
Much to cold to work in there, Duck Fat :lol

Huge thanks again to RMT1984, the servo works perfectly.
It wasn't too cold today, fortunately ,but I had a big stone pier to build for my brother in law and didn't get done till two this afternoon, so with no leccy I had to get a wriggle on...
It was fiddly. Bloody fiddly. Spent more time scratching my head and looking at it than I did spannering. Does it come out this side, that side, from the top, have I gotta take the radiator off etc..that sorta thing. It came out the top, having cut several cable ties and moved wires an that about, but it was tight, I'm talking another coat of paint on the frame and it wouldn't have come out tight lol.
Took me two hours, but it's one of them jobs that if I did it again it would take 30-45 minutes because I'd know what I was doing next time around. As long as the bike, like mine, didn't still have the AIS fitted.....
I knew I was onto a winner when I got the old one out, I couldn't turn it by hand at all had to get pliers on it to make it move, whereas the second hand spare I can turn fairly easy by hand.
Took it out for a short run to check it was ok and ended up doing the Wye valley in the dark and cold, it was brilliant. I'd forgotten how good a thou with everything working properly is. I know the exup v exup removed argument will go on forever, but perhaps it's bike specific, I certainly wouldn't be without mine, Low down flexibility counts for a helluva lot this time of year :-)

And I'm selling me zzr1100 come spring, it's a lovely low miles minter, but I can't think of any occasion I'd use it over the fazer.

Another happy Fazer owner

Do i can slip this round without undoing any bolts? I have seen a few things about the valve but little about the servo motor and how its mounted to the bike?
-
You can. I unbolted the clamp because it made it far easier to get out, it's pretty tight in there. Just take it slow mate, note where cables etc run, take pics, it's not that bad a job in truth
-
If AIS is removed no, just slip it off the mount, but if AIS is still in place probably easier to remove the bolts
-
hello could I ask when you turn on the ignition is the servo motor supposed to cycle[ mine does not]. The valve is all greased and very free the cables are not frayed or binding. If I turn the pulley on the exhaust to its stop ie opposite to the hole where the slot lines up and then turn on the ignition the servo turns it back to the start position and that's it oh and I get the 7000 code. hopefully someone can offer a solution. thankyou for any help. hambone
-
Hi Hambone,
The fact you've got a 7000 code means you've got some exup related grief.Regarding the servo cycling.If the engine has run and you've turned it off with key it should cycle the next time the ignition is switched on.However if you don't start the engine it won't cycle anymore until the engines been run.If you stopped the engine using the kill switch you'd hear it cycle then and not when you next operated the key.
-
thanks for that robbo. No cycling at all seems like motor buggered .
-
The fact that the valve is moving back to what you describe as the start position says the servo is probably fine. I suspect the cables are too tight or not correctly adjusted.
Start by removing the chrome valve cover. Then, with the ignition OFF, use an 8mm socket on the pulley bolt to turn the valve fully clockwise. Turn the ignition ON now and the valve should cycle back so that the fork is lined up with the alignment hole. Ignition OFF now.
If the fork is not precisely aligned, turn the pulley to the desired position over the hole and then pin the pulley in place with a drill bit or whatever. Now adjust the cables using the adjusters mid-way along them. You'll find these behind the top right frame rail.
With the valve pinned in place, you should have 1.5 - 2.0mm freeplay in each cable.
Unpin the valve, rotate it back to fully clockwise again and turn on the ignition. If correctly adjusted, it should now rotate back to put the fork over the hole. If it doesn't, repeat the process. It may take a few goes to get the idea of how to alter the valve position with the cable adjusters.
If you still get the 7k error code, either the cables are too tight (slacken a little more) or the valve isn't moving as freely as it should.
-
ok will do what you suggest thanks for info falcon. hambone.
-
hi exup valve is now sorted turns out it was my mistake. I stripped the valve to grease and free it a bit when I assembled it I put the pulley on 180 deg out so could not line up cables. thanks for help. hambone
