The video teaches all the steps and tools required to unrestrict and free up all the available power of a Kawasaki Vulcan.
Kawasaki restricts most of its Vulcan S model, cutting power or throttle availability specially in European countries since the bike is considered a beginners bike.
If you want to have available of its potential you will have to go straight to the dealer and to pay a hefty bill for quite a simple job if you know what you are looking for.
The video show step by step tutorial on how to unrestrict the bike and some test drives after each change to show you how much the bike can be when running free of any hurdles.
Have fun riding and be safe always. Let me know what you think and if you have any questions do not hesitate to ask
Thanks for watching the Zaska Channel.

Thank you, sir. I wasn't there when the stupid restriction law was ENFORCED but, I'm happy to have the knowledge to bring a Vulcan back to how Kawasaki's engineers worked hard to create. And you saved me €250!!!

I just got a 2022 Vulcan S and I went to check this out. The screw was already taken out so I just had to take off the restricter.

@vmac11k99 4 года назад

Your motorbike doesn't have ECU restriction. If it did have an ECU restriction, you would have loop wire on that connector, which you suppose to cut. Your motorbike has dummy plug that serve only as a weather protection. Only Australian models (that I am aware of) have both ECU and throttle restriction.

@nathangarciamuro 4 года назад

Correct. I found out at a later stage. I remove the plug to install a gear indicator which is another video in the channel. However, it is good to check the plug in case there’s is a ECU restriction. Here in Spain, the 2018 onwards I believe the restrictions are done in the ECU itself without any mechanical mechanism so the o my way to unrestrict the bike is via the dealership. Thanks for the comment.

@kardrol 5 лет назад

Cool video. Didn't even know it could be restricted I have a 2016 too. Will check that to see if I can unleash the potential :) By the way nice seats you have there. Where did you get them ? They look really comfortable.

@nathangarciamuro 5 лет назад

It is easy to do and you will see the difference. By the way, the seats I got them customized here in Spain. They got extra puffing (special gel) so they are doubled in size of the stock ones. I would highly recommend to get them redone by a specialist or purchase special ones since the stock one is terrible.

@desimotley9141 2 года назад

Thanks a lot for your awesome videos and tutorial. I love the way you explain the steps. I have question related to your Vulcan S passenger seat. Which model of passenger seat do you have? I have the standard narrow passenger seat on my motorcycle and my wife is not very comfortable on it. The seat you have seems to much more wider and comfortable.

@nathangarciamuro 2 года назад

Hello. I am glad the videos are helpful. The passenger seat is custom made. I didn’t purchase any.

@nathangarciamuro 5 лет назад

CarlosAO Houston thanks for the comment. The 2017 bikes are harder to unrestrict but if you are in the US they might not be restricted, I would ask the dealer. The restrictions are more common in Europe since restrictions means more taxes and fees and Europe loves to tax their people.

@JE-MG 4 года назад

Im in Georgia and I just got a hold over 2017 Vulcan S. I haven't looked for the screw yet but the plug is certainly there. I have 350 miles till break in is complete so I'm going to remove it then. Aside from dealership is there any other way to find out if the bike is actually restricted? And then how do you even unlock it if it is in the ECU?

@phatkhant6435 3 года назад

that plug was just a blank. the restricted version of the plug has a looped wire coming out of the top (Australian LAMS Version). there is no advantage to removing the blank as it is merely a dust cover for the diagnostic system connector.

@nathangarciamuro 3 года назад

I believe you are right. I changed it anyway since I installed a gear indicator that uses the same plug.

@davidmanchkhashvili628 4 года назад

Thank you, sir for your helpful video. I am commenting it hoping that somebody on your channel professionally advises me on how to de-restrict newer model (without referring to my dealer). I have Kawasaki Vulcan S 2018. It DOES NOT HAVE a THROTTLE LIMITING KNOB but DOES HAVE the ENGINE CIRCUIT BYPASS PLUG. My Vulcan S jerked while riding below 2000 RPM with the plug. I also could not exceed approx. 130 km/h (80 mph). I removed the plug after break-in period. Are there any other steps to complete de-restriction? I haven't measured the max speed yet but behavior below 2000 RPM is much better now. Thanks in advance.

@nathangarciamuro 4 года назад

David Manchkhashvili hopefully you will get the answer. I heard that unrestrict the bike can go from 60 to 250€ depending on the dealer. Good luck my friend.

@nathangarciamuro 4 года назад

That is the first step. However, I believe you need to do something in the computer. It is weird that nobody has performed it and post it in the Internet.

@nathangarciamuro 5 лет назад

Orville Obaldo thanks for the comment. The job is quite easy and it is really worth while. Talking to people and and a dealer that is how I found out about the plug. I first remove the accelerator restriction and I felt the difference right away. Removing the plug took me a little longer about the effect. You have to find out when going to the highway where you need full power to enter the highway.

This doesn't work for U.S.A Model the screw already removed. Connector is for the gear indicator. Maybe in other countries they restricted.

@nathangarciamuro 3 года назад

Correct. There is no restriction in the US market. You can even change the exhaust to a Two Brother’s or even a Delkevic and the bike will be fine, in Europe the bike will fail the year inspection. The bikes after 2016 are restricted via computer therefore these tricks will not work.

@brenton2561 3 года назад

Does removing that plug create any fault codes?

@skeptic3332 Год назад

The removal of the throttle stop was great, well done. The 2nd part though actually may harm your bike. That Sir is the OBD II connector for shop diagnostics. What you removed was a weather proof cap that also ties the two grounds together so you don't have a floating ground in your ECU. Now that you do have a floating ground by removing the cap you can expect a range of random and intermittent prolblems that will drive you mad. You should put the cap back on.

Can with work for Kawasaki Ninja 650 2019year? thank you so much! my ninja is 35kw, i'm dreaming for unrestrict it!

@nathangarciamuro 4 года назад

Avner Neeman my Vulcan S is based on a Ninja 650 so most probable it can be done. My recommendation is to look if you have the acceleration knob limit. If you have go ahead and take it out as I explained in the video. However, Kawasaki introduced the computer restriction after the 2017 model so you might be unlucky and need to go to a dealer.

@davidmanchkhashvili628 4 года назад

Kawasaki Vulcan S and Ninja 650 have the same engine. I have Kawasaki Vulcan S 2018. It DOES NOT HAVE a THROTTLE LIMITING KNOB but DOES HAVE the ENGINE CIRCUIT BYPASS PLUG. My Vulcan S jerked while riding below 2000 RPM with the plug. I also could not exceed approx. 130 km/h (80 mph). I removed the plug (as shown in the video) after break-in period (1600 km). Engine stopped jerking below 2000 RPM and last Saturday I reached 165 km/h (couldn't accelerate more because of traffic and lock down).

@mrandrewwong1712 5 лет назад

Hey. Would you happen to know if it's the same for the z650

@nathangarciamuro 5 лет назад

I would think so since the z650 uses the same diagnostic port to connect the Gear Indicator. But beware, my Vulcan is a 2016 model, the 2017 onwards are computer restricted and only the dealers can unrestrict. What I would do is to follow the throttle cable to see if it stops by a screw or little knob. The Vulcsn S 650 uses lots of the z650 designs so I would say the restriction design is the same as this video.

Alan Hirsch correct. I mention this limitation at the end of the video. 2017 onwards the restriction is done at the computer therefore you need to go to the dealer to unrestrict and of course pay up. It is a matter of paying. But I can tell you it is worth while. Without the restriction the Vulcan S is a complete different bike.

@kalifighter79 2 года назад

Why are they restricted in the first place?

@nathangarciamuro 2 года назад

Because in Europe, specially in Spain, there are two types of motorcycle license, A2 and A1. A2 is for bikes with 45 HP or less. Ir is mandatory to pass the A2 exam and ride for 2 years before you try to get the A1. Therefore to sell more bike and appeal to the young market then they restrict the bike from 61 to 45 HP so people like me can ride. :-)
