Hi All,
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

Top speed is definitely not normal, but why the fuck are you trying top speed runs with a possible knackered wheel bearing??? :eek :eek :eek :eek :eek
-
:agree
Is it a blue bike per chance? :lol
A possible reason for the rubbing sound could be the front discs are slightly out, have you checked them? This would cause rubbing onto the pads which in turn would heat them up, so check there too.
What revs have you got at this speed? Reason for asking is are you sure your using all the gears? Might sound daft but a mate bought a bike years ago and found out it had the top gear missing so as much as he thought he was in top it actually was only in 5th so therefor couldn't get maximum speed out of it, just a thought.
If you are replacing bearings etc make sure you grease all the moving parts.
-
Just to reassure you they do around 135, maybe a little more or less depending on the bike, but certainly should go right up to 100+ without thinking about it.
I guess in principle failed wheel bearings could affect your top speed, but they would have to be causing a LOT of friction to hold the bike back that much, and that amount of energy is going to show itself as heat.
I think if you're unsure of your bearings then it's a no brainier to change or at the very least inspect them irrespective.
But I'd also be looking closely and both brakes to see if there is any binding.
Perhaps is restricted in the carbs?

Has a restriction kit been fitted?
-
Err a 51 plate in fast blue with micron exhaust absolutely will not ever do an indicated 142 mph...that would be madness. Equally a similar bike cannot do 130..two up
-
Sounds like you have a restrictor kit fitted Dalton.
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.
-
Mine does 175 in 2nd, has custom paint though, when sprayed Kenny Roberts colours I expect it will do at least 200, on the back wheel, up hill,head wind, with the brakes on.
Don't listen to all the other speed claims, they're all deluded................

Get the front wheel off the ground, on the centre stand with someone sat on the back or a block of wood/jack under the sump. the front wheel should spin freely, I'd say it won't be the brakes as you'd smell the pads burning and the discs and calipers would be red hot at 86mph!!!
Next test the wheel bearings, full lock one side and someone to hold the bars, hold wheel front and rear if it even has a hint of a wobble replace the bearings.
I think your looking at a fuel restriction or an exhaust problem, black smoke or excessive noise? Look for 4 rubber washers behind the carb rubbers, if there remove and refit.
-
These "am I restricted" questions do appear from time to time. IF it takes so much dismantling and detective work to see if a bike is restricted or not then what happens if you get pulled over by mr plod, how do they check if the power matches your licence.
-
Fazersharp - If they have any doubts, plod impound the bike and get it checked.

Lad at work was pulled for speeding on a supposedly restricted bike, the bike was going quicker than it should have been able to so they had it stripped and checked, not sure which caused him to be banned but lets just say he was in trouble either way

I see thanks both
I wonder if they also bill you for the effort taken.
You would think that there would be some sort of anti tamper tag attached that can just be quickly looked at
-
I would probably put money on that it has been restricted as I had a somilar problem with my FZR600, it would get to 80/90 really quickly and then just loose power, I never found the restrictors but the guy I sold it to stripped it down and found them under the carbs and shazzam the power was there.
-
Mines a 2000, silver one.
I went to Hamburg and gave it a good blast on the Autobahn. It ran out of puff at an indicated 138mph. It got u to that speed pretty quick. I removed the panniers and top box and gave it another go and it did the same thing.
I've since fitted a scorpion exhaust and been across Europe again and it still runs out of puff at about an indicated 140mph, I'm sure with my head down, down hill, with a prevailing wind and a bit of perseverance it would do 141mpg.
-
Mine is bog standard other than K&n air filter. Mine tops out at 138 indicated 129 on GPS.....
-
Mines a 1999 red one with a scorpion exhaust and I've had 140 out of it and a swear it was still gunning for more :eek
-
Sh1t myself once on the motorway at 125+ the steering was starting to get a bit wobbly so I chickened out but I don't think there was much left in the old girl to be honest, that's on a '99 silver, with a very loud art can. :)
-
it would do 141mpg.
Fek me, I'll need to find out how you get that! :pokefun

A mistake that's often made...The Blue one had already arrived at destination

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).

I wouldn't know! :rolleyes :lol

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.
-
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.

Think he needs to reply to this thread a bit more otherwise you lot will make into a ver long one!!! :lol

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

"...The bike is a red one..."
Solved! :rollin :rollin :rollin
-
Blue ones can achieve light speed.
-
Mine has a restrictor in the carbs that I'm yet to take out. Still manages 110 though!
-
Blue ones can achieve light speed.
Black
A black hole can bend time and light
-
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...............

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.

Get the front wheel off the ground and slowly rotate the wheel, may be easier to hear where the sound is coming from.
-
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!!
-
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.

Have you checked the air filter, always a good place to start when top speed is down, if it can't breathe it can't go fast.
If it is ok there are two variations of restrictor kit available see pics
I have had 140 on the clock a few years ago two up on the way home from a MotoGp race. :eek
Probably the real top speed of a Red One :lol
Are you sure the noise is from the front, if so check the mudguard is fitted correctly and the tyre is the correct size 110/70 X 17 not a 120/70 X 17 as it will rub the mudguard
Also spin the rear wheel while on the stand as it may be from the front sprocket area.
As for the gear change issue, while it could be a bent or worn selector it could also be a wrong fitted gear lever
Check the punch mark on the gear shaft aligns with the slot in the gear lever
See pic
-
Are you sure its a scraping noise?
I used to get a funny noise from the brake pads/tyres which could be heard coming up through the fairing. A change of tyre tread pattern changed the noise.
-
Hi All,
Firstly, many thanks once again to you all. The top speed issue is now resolved :D
I've scared myself silly in testing it, but it now accelerates MUCH harder, and top speed is through thre roof :eek
Obviously being a red one, I was able to out-accelerate time itself, and arrived back 3 minutes before I set off, which will make the commute a little easier.
It was indeed a restrictor kit fitted by the previous owner, so removing the carbs, removing the restrictor, and putting it all back together again solved my problem.
This just leaves the noise and the crappy gear change.
The noise is definately coming from the front, and whilst the tyre is a 120, it's definately not rubbing on the fender / mud guard.
When I was changing the front wheel bearings, I obviously had to remove the speed sensor (and broke one of the exposed wires in the mean time :o ). I've ordered the replacement part, but whilst Googling it (other search engines are available), I saw a picture of a speed sensor that appeared to have bearings in it? Mine doesn't (the one I just broke the wire on) should the sensor have bearings in it? I'm not talking about the rotor here.
As for the crappy gear change, I'll take a look at the suggestion around alignment. Of all the problems I've had with the bike, this is the least of my worries as I have a work-around :lol

as for speed if I remember rightly these fazer 600 were capable of 135 mph max.

If the bike's in good condition, as in everything functioning properly, then it'll definite go a tad quicker without a doubt.
-
I never did find out what top speed my fazer(03) did ,but I do know it would hit 120 mph very quick.

At 120mph you two more gears to go :lol

Roughly 232kph = 144mph
