LAMS derestriction

Very easy to do (assuming I did it correctly lol).

Next to the battery there are some wires that go into a plug that has a loop in it. This plug disconnects into two. The part with the loop in it will stay attached to the bike. I kept it there in case I ever decide to sell the bike as LAMS compliant. Cover the exposed end of the plug with tape or something so water wont get into it. Probably no need to tape up the end with the loop in it, but I did anyway.

The bike will ride much smoother after you do this. I found it quite jerky before, particularly after easing off the accelerator in first and second.

To derestrict the throttle there is a small screw that must be removed with a torx key. The screw stops the throttle from twisting all the way open. Sorry I cant remember the size, possibly T15. I do remember it was a size larger than everything I read on the internet on derestricting the Ninja 650. If you use a long handled key like the one I have below its a simple process. If you have a set with torx bits you will probably need to remove a bracket and cable that gets in the way.

This makes a massive difference to acceleration. The bike isnt really much fun to ride with the throttle restriction in place.

Obviously if you have a restricted licence dont do this. Photo's attached. Im not sure if this applies to any country other than Australia. Apologies for the non-technical terms

Thanks a lot. I would try that tomorrow. And yes i have a full license. I got the screw part. But the wire part. Should i just like cut the wire and tape it or does one part come out from the connector hence terminating the loop. Im a bit confused on that part.

Don't cut the wire loop. Just pull the plug out with the wire loop and that's it. Tape the open end to keep moisture out as mentioned abve and keep the wire loop plug for resale as also mentioned.
By opening the circuit when you pull out the plug, the ECU loads an alternate map which opens up hidden treasure.

If you're not mechanically minded just wait until the 12,000km service.
The tank has to come off to change the plugs. With the tank off its easier to reach the throttle screw from the top down using a torx bit with a wrench.

I do not believe our Canadian bikes are not restricted, we do not have the plug they removed just the cap sealing it, have not checked for the screw
