I am planning to install a Leo Vince exhaust and considering a K&N air filter as well. My mechanic suggested the air/fuel mixture would be affected and the scooter may need to have the FI re-mapped. Has anyone with both aftermarket exhaust and air filter had any performance problems or issues?

Some guys have added a Power Commander with or without installing a different exhaust. You can then fine tune your fuel map yourself with downloadable maps from Power Commander.

For Power Commander info on this forum, try here:

BTW, out of curiosity, are you buying your LeoVince in Canada, or bringing it in from the US?
