Hello. I own a Yamaha neo's 4. Its a 4 stroke and have quite good restrictions, if you ask the goverment. It goes about 49km/h up and downhill. And has a ecu restrictions wich means i have to remapp it. Wich is very hard because i need to go to a yamaha center and find someone who wants to do it, they dont. But ive heard that you can change the whole variator and thereby pass get better top speed but your moped is still restricted. What about if i just change the variator weights. Will that work? Sincerly,
Will only make a small difference Found this for you but, not sure your looks like this as have older one with different cdi unit You could always email them as does not list Neos 4, but worth a go Also check if fits do you have to get any thing done by dealer, mapping etc, or straight swap https://www.pedparts.co.uk/product/50/aerox-cdi-unrestricted-max-performance
