Yamaha aerox

Hi I have a Yamaha aerox 2013 new shape and I have ordered a yasuni z exhaust the moped is currently fully standard apart from being de restricted and my original plan was to just fit the exhaust but I am now thinking that could be a bad idea as people say it needs to be tuned, please tell me your thoughts but don't take the mess

 

You will need to re-jet the carb to suit the pipe, thats all.
But if you can't do it yourself, I suggest you find someone who knows what they are doing because you can easily be running it lean which will lead to a seized piston.

 

Ok thank you that's great I think I am going to find someone who can do it thanks for your help

 

You wouldn't have any idea on what size jets I will need would you? Would be much appreciated
