Hi.

I am looking to buy a ZZR 600 E model 2001 restriction kit.

I don't care if you have the certificate or not as this proves nothing, it is the washers I want.

What do you have and what is your price?

thanks.

If you hear of the washers for sale then please tell me. I'm posting this around a few bike forums including the ZZR specific ones.

I saw them on ebay a few weeks ago and they went for £1.

FYI, just in case you dont know the engine is unchanged from 1993 (eg the E model) onwards, only changes were largely cosmetic.

So any restrictor kit for an E model should work.

Someone from a bike forum said that he has the kit but won't sell it incase he needs to re-restrict his bike. I take it he's riding unrestricted on a restricted licence.

Anyway, he said he can measure them for me in a couple of weeks. Does anyone know what materials and tools would be needed to do this. It can't be too hard and I do have free access to a motorcycle workshop.

as far as the law or your insurance are concerned, then i think you might want to shift your stance on this one.

it might just be a simple case of fitting washers in the inlet manifold/exhaust, or restricting the throttle movement, but without a bona-fide cert from a reputable dealer, then you're skating on thin ice.
if you do get stopped & have a cert, then you're more likely to be sent on your way without any fuss, without any proof, then you could end up with the bike impounded & all the costs that involves.

Yup, you're probably right with that one.

You can buy the certificates from ebay for £30 so I may get one made up anyway.

Change of plan. Miz has offered to make me the washers.

For anyone that is interested, this is the measurements.

36mm outer diameter.
9.96mm diameter hole.
2mm thick stainless steel.

The holes are positioned off centre. This is what they should look like:



From the looks of things, holes will have to be made for the screws that hold on the rubber things (are they called inlet rubbers?).

If I can't get the measurements then I can always measure my own bike.

edit: Miz, you could always leave the space for the holes blank and I could drill my own holes. It could be best to give extra material than the 36mm just to make sure that they will fit.

Hi,

It looks to me as though the "washers" are actually the same shape as the flange on the inlet rubbers, so you will need to make sure you get a good seal when you fit them, if there is a gasket between the head and the inlet rubber at the moment, I would suggest fitting a gasket between the head and the washer, then another gasket between the washer and the inlet rubber.

If you can send me a drawing of the flange of the inlet rubber (or if you have one removed trace round it) I can then produce a cnc file to cut the washers (I'm certain that the position of the 9.98mm hole does not matter too much).


Miz.

Just a thought, you could get the bike onto the dyno once the washers have been fitted, the printout will have date, time and bike reg on it and prove the max bhp.



Miz.

I don't know why you just get it done properly

I'm curious as to what figure you would compare the dyno output to to prove it was legal since the 33bhp legislation is measured at the crank, not at the back wheel.

I have to say that this thread has clarified my feelings on the matter and I think the legislation should have just been done as 33bhp bikes as given rather than allowing bigger bikes to be restricted to match. The current system is just completely impossible to enforce consistently/reliably. (I dont even particularly blame you david for trying to play it, its the system itself thats flawed!)

The main reason why I want to do the restriction without just paying and getting it done is the money.

The washers are £170 and any place that would provide them would make you pay for them to fit so it's going to cost even more for labour.

I don't know. I'm tempted to just buy the certificate and get the washers made up. Then if the police have any issues just say the previous owner restricted it and just act dumb.

The bike will clearly be restricted if they dyno it anyway. Would I seriously lose my licences and get banned if it made 34bhp at the crank?

Also, how does anyone even know?

I think they should make DAS available to under 21s who have passed their restricted licence. If 17 year olds can be trusted with a big car in which they would more than likely do more damage to other people if they crashed, then why can't they be trusted on a bigger bike where the rider is the one that's most likely to come worst off and not some poor person who wasn't doing anything wrong?

Anyway, there's no point in looking for logic in this as nothing will change. The teens with no self control just ruin everything for everyone else. Lots of people my age are idiots. They all talk about racing and think that driving at 110mph on a straight road is skill. They drive while on drugs and do 70mph in a 30 zone while passing side roads. (have been in someones car while this was happening and wasn't too happy).

i am contradicting myself here as I certainly wouldn't give any of them a bike licence. I guess I am more sensible because most of the bikers I talk to and ride with are at least in their 30s. Regardless of what I think I can do though doesn't change what I am required to do by law. That is being restricted.

Now if it wasn't so damn expensive!

I do.
A proper restriction kit, purchased from a reliable source, fitted by registered 'professionals' and the documents to prove it's all legit cost's a packet.
My restriction kit for the GS (Two washers, one each in the inlet manfold) cost me about £200 IIRC.

I've not been asked by my insurance company to provide any proof of restriction... YET, I'm guessing I'll have to provide it if I'm unlucky enough to have an incident.


<EDIT> David beat me to it

Cheapest I paid for a FI International restriction kit & that elusive red piece of paper was £175 fitted. Friggin RIP OFF. The washer kits are made in Germany out of cheap dirt. Couldn't cost FI more than a fiver cost. Its just 1 big fat rip off.

Rant over.

David, I have an official FI kit for a Honda. I'll go out to the garage later and measure the washers up... you never know...

Johnny

Sorry David. Too big. 45mm outer diameter and a bigger inlet hole too.

Oh dear, So it's expensive.
Life's expensive.
Do things properly, be legal and then there's no worry about losing your licence is there?

Moan about spending money to be legal or sit on here moaning about how you lost your licence because you put some shonky washers on yer on yer bike and bought a dodgy certificate on ebay.
No contest really.

Other people do it - what makes you so different?
If you couldn't afford to have the bike restricted - why did you buy the bigger bike?

I'm getting really sick of this now. I have warned you where this conversation was going but still it keeps going.

To be fair i think its a fault with the system, and David is getting there, slowy but surley.

I have spoken to my mate for ages on the phone about restriction.

We spoke about the situations I may find myself in with insurance and the police. Being possibly unrestricted (what if I got the wrong measurements for the washers?) also those certificates you can buy probably won't be linked to a dealer nearby or even one that exists and might not check out.

I guess the £200 that I'll have to pay for those 4 washers is the worst value for money I've ever spent, but if I don't do it then I'll probably be looking over my shoulder for the next year.

I have only had bad experiences with the police, not giving a feck when someone hits me on purpose when I give them the licence plate and and the other time they gave me a fine (fair enough I should have had my tax disc on me, but £60 was abit much for a £15 tax disc that I had paid for a week before. At least there was no points given.

They will use any excuse to give me a fine or take another biker off the road. At least when I'm pulled I have that certificate and FI international washers fitted. I will not be constantly looking over my shoulder worried about what might happen.

Also, the price of doing the DAS would have been much more than the A2 so it kinda balances itself out. Especially as I could lose not only my bike licence but my car licence too.

Thanks to everyone that helped me out, but not to the ones that complained as I was just trying to be legal and save a bit of money at the same time.

Just kidding guys, I do know you're just looking out for me.

There has to be other companys who make restrictors as well as FI International, a company who i think are always vastly over priced for their stuff.
Im pretty much sure that they only sell restrictors to trade, which makes your chances of buying a bargain zilch as you are stuck paying Dealers price for supply, fitting and paper work.
Hopefully you will have your bike restricted soon and you will be able to enjoy many miles of trouble free biking.

The LAW only states that your vehicle must output no more than 33BHP, it doesn't say anything about having to be restricted by a certain method or that you are required to use a certain company. So the only hurdle is the insurance.

Ask your insurance company if your restriction MUST be supplied by Fi or if they accept a home-made restriction as long as it's backed up by a valid Dyno certificate.
If they say that it's OK to BluePeter it, then you might be able to get 2nd handers off Ebay and do it yourself.
