GS500E Restriction

[scarborough_lad]

Hi, I'm trading up for a 1998 GS500E in a few months after I pass my test. It'll need to be restricted and I've been looking at ways to do that. FI want £200 for some washers, and I'll have to get them fitted so that's £250 all in. I was wondering whether a kit like this would be more cost-effective.

https://www.ebay.co.uk/itm/Suzuki-GS-500-GS500-Restrictor-Kit-33-BHP-25kw-certificate-/320958417991?pt=UK_Motorcycle_Parts&hash=item4aba9ccc47#ht_1238wt_884

It's still £42 but it's the best I can fine, unless anyone has some second hand ones they can sell me? Just looking for opinions, cheers!

Just thinking if it's good idea buying these off eBay. How do I know if they're proper and won't drop me in the shit when it comes to insurance or the po-po?

they're great. Really easy to fit and restrict it well. Plus you get a certificate.

Get a frequency switch kit, connect the output relay to the sidestand switch and peg the rev's at about 6k (engine makes about 30 bhp there looking at a few dyno graphs.)

Will make lots of popping banging noises, costs £7, and has an on off switch so when you do get pulled up, click your switch to enable the limiter. Youtube Bee*R limiter. Basicly does that, without the pricetag. Flames and bangs depends on fuelling, revs and the gain setting on the PCB.

Havent got mine permenantly fitted as i'm making a few mods to the board and trying to find a suitable waterproof housing to put it in, but have had it on the bike and it does quite happily drop the rev limiter to wherever you want it set. Five wires. One to the yellow and black on the CDI, one to the + on the battery, one to the - on the battery and the other two to the sidestand switch (green and black i think, i'll write up a guide once i've got it setup 100%)

Cheap, quick and will fit any carbed 12v bike. Probbably the EFI ones aswell, but the install would be different i think if the ECU controlled the spark instead of a standalone CDI unit? Not sure.

Or be a good boy, and leave it 33bhp all the time. in which case run the washers off ebay at about £40 a go. Kickstart engineering i think?

Legality as i understand it;

Certificates legally dont count for fuck all. They're worthless paperwork.

If insurance ask for proof of restriction, take the bike to a dyno. Get a power run that shows it only made 33bhp or less. Have the operator sign this paper, and send them that. I've never been asked for any of this certificate nonsense.

Police wise, they dyno your bike, it simply wont rev high enough to make 33bhp, and unless they can PROVE that your limiter wasnt switched on then they cant do jackshit apart from be angry at it.

In the event of an accident, if the PCB is there, this is evidence of a restriction device, and thus proof enough that the bike probbably was restricted which gets you off the hook as you can claim that it was damaged in the crash.

From my experience;

I ride the bike everywhere. It looks like it's escaped from the scrapyard. It sounds like - and i quote "Spawn of satan". I've never been pulled, never had any greif with the old bill, never had an insurer ask about a restriction certificate. I did get stopped by the police once limping it to a petrol station with a flat tyre, and had nothing said. Previous experience of popo says that if you're alright with them, have a laugh and a joke and try and be as freindly as possible you'll be fine. If the car says traffic police on it, dont bother as they're jobsworth cunts who WILL fuck you for whatever they can.

You get a dyno chart for said bike, wherever that says 30bhp? 20bhp? Whatever you want it to make, you note the revs & set the board to do this.

The board monitors a pulse input, i.e from your ignition coil. This tells it what revs the engines at.

At a set rev the board trips a relay. You wire this relay to the sidestand switch, or ignition kill switch.

Revs rise to the point where the engine makes 30bhp, board detects this and switches the engine off.

...For the amout of time you tell it to by adjusting the VR3 pot (tiny one on the board) Then switches the ignition back on.

Long delays give this effect;

And a short delay gives this effect;

The engine then tries to spin up to x amount of revs again, and the board turns it off. then back on again. then you get the bababababa like when it hits the OEM limiter?

However, if we then put a simple on off switch to the + feed for the board, then when the board sees no power, it cant switch the engine off. thus engine runs as normal. So if one were to hide a switch up on the bars somewhere? or in the fairing? Idk..

If your bike has a coil or electronic rev counter for the signal, and killswitch or sidestand switch then it'd work. Provided its a 12v electrical system.

I like flames, bangs and generally being a bit of a pikey. However doing it this way then gives me a legitimate excuse for having such a device on my bike. Although i sure as fuck wouldnt want to hit it whilst riding. I reckon if i got it set up right it could make for some awesome burnouts.

I'll await being flamed to f*ck by the kittendeath crowd & am in no way suggesting that the information posted by myself should be used to break the law or licence restrictions. Just saying that it COULD be done.

Haha I love the disclaimer at the end.. Just thinking this sort of restrictor could suit me.

Ha! I never noticed that one though I saw that thread... And would your discussed, not at all promoted or advised restriction method invoke similar anger?

No idea. On/off switch reffered to is a diagnostic switch btw for fault finding.

Obviously if one was to crash and the impact was to knock the system into diagnostic mode...this would explain an iffy dyno reading wouldnt it?

All theory though. I still need to figure out waterproofing, packaging, set it up propperly and test ride it over a few thousand miles before i can comment on the systems reliability. I also intend to get it dyno tested after a driveway guestimate calibration to see how easy it would be to setup using the OEM tacho & google images dyno charts.

If i can get the thing working, road tested and everything i'll post a proper how to guide.

That would be horrid to ride. If you restrict it to 6k RPM that means you would only be able to get to about 60mph. Do it properly the bike will be much more ridable.

The "kit" you need is two 38mm washers with 20mm holes drilled in them and stuffed between the carbs and the engine.

The "certificate" that you'll get from FI international or anywhere else is a piece of paper that says "Yo, is totes 25kW 4 realz!" on it. If you have a printer - or a crayon - then you can produce an equally valuable piece of paper which will prove exactly the same (nothing) about the actual bike.

33bhp certificate rip off.

I think I'm going to be a good boy and get the kit, that board sounds interesting but seems too complicated for me. It sounds like you can either ride illegally or backfire like a bitch, not too keen on doing either.

Cool, thanks for all your advice everyone. I'm gonna go with this kit thing.

Has anyone on here actually had their bike dyno'ed by the filth?

What's-his-name who stacked it into a farm gate, I'm not sure we ever heard the conclusion of that one. Actually, was it dyno'd, or did they just say "Dear Mr What's-his-name, there's sod all evidence of restriction on the remains of your bike, so since we're doing you for Careless anyway, want to tell us what your defence would be to an Otherwise Than In Accordance charge?"

Then there was the epic thread at the SV650 forums about the youngish chap who was nabbed (unlawfully, I believe) and then the dyno place caught fire with his bike in it And he wasn't prosecuted in the end, even though Plod claimed his bike was reading more than 10% over.

Don't crash, don't get caught at 3 figures, ideally have a bit of paper to wave at Plod or insurers, and I reckon the chances of being accused let alone convicted are absolutely minimal. It's not an obvious or easy collar, and there isn't the budget out there to police it pro-actively.
