it would do 141mpg.
Fek me, I'll need to find out how you get that! :pokefun

Does it accelerate rapidly to that speed then stop accelerating or does it just run out of puff at that speed? If the latter, then I would definitely think it is restricted. If the former, it could be clocks related. I have heard something about the rev counter link to the ECU. Others will know more about that.
If it is a black one, indicated 145 is possible though in reality it is more like 130. Obviously this test was carried out on a private motorway in deepest darkest Kent on a quite summers evening with another black FZS600 keeping pace. The blue, red, gold and silver ones couldn't keep up.
A mistake that's often made...The Blue one had already arrived at destination

A bit of a back story coming up, but I (think) I have a problem with the top speed of my bike.
About a year ago I bought myself a Cat-D write-off 2001 FZS600. All it needed was new forks, and front fairing.
So me being me, I decided to do a twin Xenon headlight conversion instead of replacing \ repairing the front fairing.
A knock-on effect of this was that I needed to replace the clocks as they got in the way of the headlights, so I fitted a KOSO DB-01R Digital Clock.
(Ok, I probably needed need to, but I wanted too!!)
Anyway, after much fun trying to get the digital clocks setup, I finally got it booked in for an MOT, and it PASSED :eek
Since riding it I noticed there was a constant "scraping noise" coming from the front wheel, so I stripped down and rebuilt the front calipers. This didn't help and the scriping noise remains, so I've just ordered a set of bearings, but have yet to fit them. It could do with a service too no doubt.
Before I had kids I was always a Suzuki Bandit man (will I get shot for saying that on here?), Now that my kids aren't babies anymore, I'm back to biking, hence me buying the Fazer.
So, back-story done, we come on to my current issue. The top speed of my bike appears to be 86Mph. My Bandit 600 was always good for 115-120mph. I've verified the Fazer speed with a GPS Speedo on my phone, and the new Koso Speedo, and the GPS Speedo are remarkably close together, with only 1 or 2 mph variance.
So my questions would be:
Is this poor top speed normal?
Would knackered front wheel bearings prevent a FZS 600 form going over 86mph?
Any other ideas what my issue would be?
Thanks all
Dalton
So what happens at 86mph Dalton - are you at full throttle ? At what speed does winding on more throttle stop making any difference, does it misfire at that speed, what RPM's is it running at, does it stop at 86mph in 4th, 5th, 6th gear or in all of them? - it's difficult to give any real feedback without a better description of the problem.
I put a restrictor kit on our sons 600 Fazer when I bought it, as he was only 3 weeks past his 17th birthday when he passed his test - but even so, it would eventually get up to just shy of 110 mph in the right conditions if the throttle was teased on gently after the restrictors effect kicked in, in top gear. The thing was though, because it was a carb restrictor kit, it would run out of steam in all gears at around 7,000 rpm (the sign of a restricted one) and once you reached 2/3 throttle, opening it further had no effect whatsoever.
With the restrictors removed it flies - it's indicated +140 mph at the Nurbutgring after the gantry on the final straight and it got there with ease. Oh, and it's a Silver '03 model (no top box on at the 'Ring though).

135mph, with a passenger, been there done that, and only shut off 'cos a car moved into my lane about a quarter of a mile ahead of me, but it was still going strong otherwise.
As for yer mans bike, i would say it HAS to be restricted, otherwise for this particular bike to have such a poor top speed through a fault i'd imagine it would run and sound like a biscuit tin full of nails, or if it was an air leak for instance it would be bogging down like mad.
Even when restricted though i'm sure they're meant to go faster than that, so something is certainly very wrong either way.

Depends on the type of restrictor fitted and where it's fitted (according to my engineer friends and co workers), as the one that was fitted to my FZR just killed the top end speed.
Re: Top Speed 2001 FZS600?? - darrsi - 17-06-16
Okay, so according to this fella, they do around 90mph when restricted to 33bhp, which would point even more to the OP's bike being restricted as well.

Re: Top Speed 2001 FZS600?? - Dalton Godwin - 22-06-16
Hi all,
Firstly, Thanks very much to everyone that responded. I thought I'd set up an email alert to tell me when people were replying to my thread, but clearly I hadn't, so apologies for not replying sooner, as I thought I'd had not responses!!
The bike is a red one
I'll double check the gears in a bit, but I'm reasonably sure I'm in 6th gear when it maxes out. I wouldn't say the bike accelerates particularly hard in any gear (compared to other bikes I've had). Ok, so it accelerates harder than the shitty Vauxhall Nova (that thinks he's quicker than me), but so does my 1.4 Scirocco. So to answer this I would say it saunters up to 86mph, and then stops accelerating.
I've changed the wheel bearing today, and I'm just in the middle of an oil & filter change.
It's an interesting point about the restrictor kits. I've never heard of them before, so I wouldn't really know what to look for.
Are there different types, and how did I identify them?
Regards
Dalton

Blue ones can achieve light speed.
Re: Top Speed 2001 FZS600?? - Aky208 - 23-06-16
Mine has a restrictor in the carbs that I'm yet to take out. Still manages 110 though!

Re: Top Speed 2001 FZS600?? - unfazed - 23-06-16
And a red one needs to be restricted to allow the black and blue ones to keep up :lol

Mine looks fast, unfortunately it only goes as fast as I can push it atm...............
Re: Top Speed 2001 FZS600?? - Dalton Godwin - 23-06-16
Hi All,
A bit of an update:
Scraping Noise:
I've replaced the front wheel bearings, but the horrible noise (continuous scraping) is still there, even at 5mph.
The calipers have already been cleaned up, so I don't think it's sticking calipers. It's doing me head in
Top Speed
The bike thanked me for the oil & filter changed this morning, saying it felt like it's had a good clear-out. We all know how that feels :rollin
Unfortunately, it wasn't grateful enough to go over 84mph!!
I've heard rumours that Fazers don't like after-market Speedo's (speedometer, not the swimming trunks, although I understand they don't like those either).
I've therefore put the original clocks back on, but still no joy get past 84mph this morning :'(
If a previous owner has put a speed restrictor on, where might they have put it?
Also, an issue I've not posted about before, but I understand it's quite common, Going from 2nd to 3rd gear, whilst the gear selector moves up, it doesn't seem to engage 3rd. This means the process is... 1st to 2nd....2nd, clutch in, left foot up, left foot up again, and I'm in 3rd (definately 3rd).
Aparently Fazers have something inside the wears and can be replaced?
I think I've bought a bit of a lemon here. Yes I know it was a Cat-D, but these problems seem endless :'(
Any advice much appreciated.
Dalton

Get the front wheel off the ground and slowly rotate the wheel, may be easier to hear where the sound is coming from.
Re: Top Speed 2001 FZS600?? - Dalton Godwin - 23-06-16
Hi mate, thanks for the reply. I've tried that one, but can't hear anything other than the calipers passing through the pads.
I'm wondering whether the forks are mis-aligned as I've replaced the forks as part of getting it back on the road after the Cat-D write-off?
As with the other stuff, who knows what the previous owner did to it!!
Re: Top Speed 2001 FZS600?? - BBROWN1664 - 23-06-16
restrictor kits, if fitted, go in the carb to stop the needles opening too far or in the airway between the airbox and the engine (could be either side of the carb) to prevent too much air and therefore fuel reaching the engine.

If the forks were misaligned you'd have trouble putting the spindle on, so i doubt it's that.
