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!!!

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!

Blue ones can achieve light speed.

Mine has a restrictor in the carbs that I'm yet to take out. Still manages 110 though!

A black hole can bend time and light

unfazed · « **Reply #33 on:** 23 June 2016, 09:03:43 am »

And a red one needs to be restricted to allow the black and blue ones to keep up

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

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.

Dalton Godwin · « **Reply #37 on:** 23 June 2016, 10:23:21 am »

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!!

BBROWN1664 · « **Reply #38 on:** 23 June 2016, 11:07:16 am »

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.

Probably the real top speed of a Red One

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.

Dalton Godwin · « **Reply #42 on:** 24 June 2016, 03:22:31 pm »

Hi All,

Firstly, many thanks once again to you all. The top speed issue is now resolved

I've scared myself silly in testing it, but it now accelerates MUCH harder, and top speed is through thre roof

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

). 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

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.

johnakay · « **Reply #45 on:** 24 June 2016, 09:39:02 pm »

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

darrsi · « **Reply #47 on:** 25 June 2016, 06:58:40 am »

Roughly 232kph = 144mph
