Restricted Suzuki GSXR 750Y

ynotgofast

Help!
I have bought a Suzuki GSXR 750Y year 2000 from some scumbag on ebay, the guy told me it was an import but didn't tell me it was restricted. It is unregistered and the frame number is intact. I know I should try and get my money back but I suspect it will be my word against his etc. It will not rev above 7000 rpm and is down on a lot of power (struggled to 83mph downhill at Cadwell Park).
Any suggestions please? (About the bike not the seller)

Ring a dealer/garage and find out how much to de-restrict.

Some bikes are very easy to remove the restriction others require you replace parts.

If it's going to be new parts I'd be looking for my money back.

Did you not take it for a test ride before parting with your hard earned readies?

Hi,
Thanks for the info and advice, I thought about a test ride but as it was not registered I decided not to risk it, I just flicked through the gears while the engine was running, even if I did I'm not sure if I would have revved the nuts off of it. I paid £1650 and it is in good condition with new tyres so if it doesn't cost to much to fix I might not come off to badly. I went to buy it as a track bike until I saw the condition then I considered putting it on the road. If the track bike is an easier option now I could go back to plan "A".
What do you make of this?
I was explaining the problem to another rider, I started the bike in neutral and it revved to 14000 rpm, I put it in gear and revved again and it only revved to 7000 rpm. Problem is it won't do it again, did I follow some sequence on starting it up?
My neighbours are going to love this one.

Sell it to someone on a restricted licence, no point throwing good money after bad, you have no idea what else is wrong with it...

sorry, not to technically minded in these things, but are you sure its restricted, and not just knackered?

ynotgofast

Well I suppose that is a poss but it still should rev while not under load, it seems to hit a limiter at 7000. It doesn't rattle anything my old cbr6 which jangles like a bag of spanners and still quite quick.
I spoke to someone who knows someone etc. who bought an RC30 from Switzerland which was restricted.
He took it to Dynotech in Basingstoke and they sorted it for him, so thats where my bike is going on March the 8th for a £50 diagnose and then they'll phone me and let me know the damage and I can decide what to do. Til then I'll keep my fingers crossed it's not knackered and I'll keep you posted.

It might even be worth more restricted than an unrestricted one...

ynotgofast

Do you think so, I suppose there are a few youngsters who can't wait to get on a sportsbike. I must admit I don't know anything about restricted bikes. I'm not sure I have ever seen a restricted bike advertised.
Thanks for that, you have just given me another option, I'll wait and see what the garage says and decide what to do.

Without certs the restrictions not worth much to a provisional rider.

And if its a kit, such as an R1 restriction, theyre handy enough to remove. Not saying how here, if you dont mind though.:)

Didnt think that bike came factory restricted, so hopefully its not your CDI or anything. And fingers crossed its not a tired engine either.

How's that? You don't need a cert to be legal. Unless it's factory restricted you won't get an insurance discount. Certs are easily faked and legally worthless.

How do you know its restricted? How do you prove to anyone who asks (police) that you are legal. They dont bring a dyno with them. If you have a bike that is restricted without documentation you have to go through the whole rigmarole of testing that before its worth anything to you in terms of proof of your road legal status. I wasnt thinking of any insurance issues.

Would that be a mechanical or electrical restriction and where should I look for it on the bike?
If it is mechanical I should be able to do it myself, I don't like electrickery though, you can't see it and it bites.

Without proof on a dyno, you or anyone else doesn't.

You certainly can't do that with a piece of paper. Especially one easily faked and with no legal standing whatsoever.

They dont bring a dyno with them.

That's their problem. If they are accusing you of breaking the law it's up to them to prove that you are. It's not the rider's fault that the law is so stupid as to be practically unenforceable, or that it has zero road safety benefit anyway.

If you have a bike that is restricted without documentation you have to go through the whole rigmarole of testing that before its worth anything to you in terms of proof of your road legal status.

Again, a piece of paper with no legal status proves nothing. Even if the bike had been restricted at the time the piece of paper was printed, it could have been removed since.

If the bike is risticted,it can be done in one of two ways. There could be washers in the carbs that restrict the amount of air or it could be electronically done via the CDI unit. Either way they are both easy fixes.Hope this was some help to you.

ynotgofast

Guys,
Thanks to all that have given me help and advice.
I picked the bike up yesterday from the garage and the problem was the linkage to the second butterfly in the throttle body was not working, hence the low revs on only half throttle.
The dyno sheet says 120bhp @ 13000 rpm at the back wheel which the mechanic says is right so I now have a healthy Gixxer 750.
Once again thanks to all.
Can't wait for the next trackday. ;-)

happy ending, thanks for the followup

quick one, how come a 8 year old bike is unregistered?

Could it be a track / race bike that has had the original fairings put back on??

Unregistered? The discussion was around - unrestricted bikes.

Id say its an import that hadnt been put on irish plates yet.

more than likely, maybe ynotgofast could clarify it.

Who knows?
The good bits.
I bought the bike as an unregistered import, I have a certificate given to me by the previous owner that says the VIN is correct and the year of manufacture Sept 2000.
I phoned the number at the bottom and the certificate is genuine and the bike is not registered as stolen.
The mechanic that worked on the bike told me that it is not a 2000 model, it is either a 2001 or 2002 so slight bonus there.
It has been drilled for a number plate.
It doesn't have scuff marks from boots on the swinging arm etc.
The wheels are in excellent condition so not too many tyre changes.
New Tyres
Low mileage 1527

The bad bits.
It has the wrong size battery.
The low fuel light is always on.
The fairing has been taken off at least once (maybe to look for the rev problem).
Low mileage 1527
It may have been tracked but not by a good rider.
I bought it to replace my old steeliie cbr600 trackbike, I paid £1650 and now I know it's mechanically sound I'm happy. Plus if I don't like it I have the option to register it.
What do you think?

Not always, if it's the CDI unit then you could have to pay hundreds for the unrestricted one. Some bikes have washers welded inside the exhaust headers which are intentionally practically impossible to get at. Some have different carb bodies or even different camshafts. Derestricting a factory restricted bike makes it worth less, so why spend money (up to a grand, in some cases) to make your bike worth less? Sell it to a learner and get an unrestricted bike.
