Deristricting a 33HP sv650
 

Hi there

I was wondering if anyone knew how to swap the engine management black box on my K4 sv650s? I was pretty ok with 33HP, but I'll be going to th nurburgring soon and dont want to get swamped on the autobahns!!! :D

Welcome.

Remove the plastic side panels either side of the riders seat.

Remove the seat.

The box is just behind the battery. Swap the box, replace seat and side panels and you're done. 8)

Thanks for that :idea: ... I have a laserline alarm- If the alarm is disarmed, will it be ok if I take off the side panel and the seat. Also, I do I have to disconnect the battery to not damage the black box and will I need any special tools for removing the seat?

Thanks

Don't know about alarms, don't have one. As for unplugging the battery, no need. Just make sure the ignition is off.

All you need to take the side panels/seat off are 2 alen keys, which you'll find in your tool kit.

There shouldn't be any problems with the alarm. I have a datatool system 3 alarm and you can leave it on while you replace the restrcited ECU with a derestricted one.

I just swiched the ECUs and went for my first deristricted ride. It was jaw dropping :D - the motor was smoother everywhere and the pull past 8000 let me blow people away on overtakes. Definitely feels safer too, coz i got more in reserve. THo I only got 95 miles to the fuel warning light :wink:

:cry: ... I can't wait(but I'll have to) :cry:

6th June - my restrictor comes out :twisted:

Get used to the power, then you could try the TRE and TPS mods. They are a little bit more complicated to do, but are supposed to make the new EFI bikes even better... :riding:

why wait? - dont you have the full power ECU with you? My girlfriend didnt want me to swap the ECUs when i told her, so i'v done it without tellin her! :lol:

If you have a 33bhp restricted licence, then you should be aware that if you swap for the unrestricted ECU, you are riding while 'otherwise in accordance with your driving licence.' This is exactly the same as not having a driving licence at all. It also means that you are not insured, as one of the stipulations of vehicle insurance is that the driver ha the necessary licence to legally drive/ride the vehicle.

Not lecturing here or anything - I'm hardly in a position to do that! :roll:

I also know people who rode like this...

However - If I had not been on a restriced licence, riding with the unrestricted ECU in when I had my accident recently, I would not regain any costs from the other party's insurance, I would have difficulty making a Personal Injury claim against the cretinous car driver and would probably be facing a criminal proceeding from the Police. I could even be open to a civil proceeding from the person that nocked me off - even though it was 100% his fault! Makes you think!!

...what he said :plod: 8-[ :evil:

Get well soon mate. Those injuries look very painful :(

I know how you must feel about your poor bike. Its hard to think this way, but it's only a bike and can be replaced.

well said Tim. We both know people who rode illegally in this manner...I for one am a little uncomfortable with this pratice...I understand the frustration and unfairness of this law but it's the law and break it at one's peril 8)

As much as it seems unfair that we have to wait two years to get onto a bigger bike, where as car drivers can drive home in a ferrari straight after their test, taking out the restrictor is a really really really stupid thing to do, as when you do eventually have an accident, you will have a new one torn for you.

It's quite depressing that bikers are in two groups, those who have had an accident, and those who will have an accident.

At least I acknowledged that I would, i know i'm not invulnerable.

Similarly, car drivers are seperated into two groups , those who have caused an accident, and those that are about to by running that red light.

Good points about the licence....I guess I thought that changin the engine ecu was like getting a more powerful exhaust. i didnt think about the insureance etc etc.
Since its really good for the kind of speeds i can't afford to do (6 points and I'm banned :cry: ) i think i'll switch back. Do you think i can use it unrestricted for tract days tho?

Restrictions only apply to the raod so if you feel comfortable with it use it on the track. Also, your limit of six points on your license is for 2 years from the date of your FIRST license, i.e. if you got a car license first then it is for two years from the start of that, and doesn't reset to 2 years when you get your bike license.

Technically, no. As I understand it, for track days, you still need the appropriate road licence for the bike you are riding. Maybe wrong though! :?

I was under the impression that u didnt need a road licence to race,

Thank you for being sensible and putting back in the restricted ecu!

i too am at 33bhp untill jan 22nd and it always winds me up when somone takes them out early! however, you now have my upmost respect, for putting them back in!

i know how frustrating it is, but it is for the best!

Best regards
Safe riding

You dont have to have a road licence to race, just a race licence. However, most Track Day organisers require you to have an appropriate road licence.
