My 2012 agility with a smooth boss runs at 41-43 without any modifications to the CDI, although I'll probably try to remove the purple wire to check.
Ok, I just checked my CDI and found that I do not have a purple/violet wire. This confirms not all 2012 Agility 50's are restricted.
All i know Exe is i emailed Kymco Uk tech dept a month or so ago. I asked if a 2012 Agility cdi was restricted from new, here is the reply i got back,
" The situation with the Agility 50 cdi has not changed since their introduction, the cdi has a rev limiter fitted on all models leaving the assembly plant.
Regards."
Where are you Exe? Maybe your country is different? If Kymco UK say all Agilitys leave the factory then i assume that means global? Maybe email Kymco Tech Dept yourself and ask then post up what answer you get back just to see if they match or not?
I know i read someone on here recently who said they cut a wire and their speed jumped a good 5-10mph on a newer a50? Mine is a 2008 so i dont have the problem, mine was easy to cut.
