I've very much caught the "I need a Wee" bug, and have been researching various used options around me (Austin, Tx). There are a few available from a range of years, which brings me to my question:
The only major change I'm aware of (apart from ABS availability) in the Wee's history is the move to two spark plugs in 2007. Does that help efficiency or performance in a meaningful way, or was that primarily just to pass emissions standards in some place that I'm not?
Cheers, Jeff
