Hello Sergio
If your Vertigo is running rich then your dealer which you purchased it from should sort the problem out
You shouldn't need to buy the WiFi unit to cure it!!
The dealer if he is any good, and he supposed to be if he has been chosen to distribute the bikes for Vertigo, test the bike with you and you can show him your richness problem, then he can sort it
I haven't heard of any Vertigo riders in the Uk having such a problem!!
regards
Stephen
