When I bought the bike the previous owner had all sorts of fueling issues and had the dealership install the Rexxer flash, which is a brand of mapping. He is also the one who put on the Ago pipe and crossover. When I got the bike it had a huge flat spot between 5-6K rpm and I didn't like it. I took it back to the dealership and they installed the latest version of the Rexxer map and unplugged the oxygen sensor as it had apparently been left in and was fighting against the map? Maybe that makes sense to someone smarter than me.
The bike runs wonderfully and that's why I haven't jumped right on a Beetle map in a great hurry. Plus my wife is all about the bathroom remodel that we're muddling through so much of my spare time is spent there. My main interest in a proper map is fuel economy as I'm itching to take a weeklong ride through Arkansas this fall and don't want to have to carry a spare tank with me. There's a very good chance that a proper map will provide an even more satisfying ride but I don't know yet. Also I'm wondering if a new map will take a little snap off the throttle...it's a bit TOO responsive, if that makes sense. I suppose it could be the driveshaft?
It rides well in the city or open road but I prefer open road. It loves to be over 4K rpm, sweeping through curves and going up and down hills. I've recently purchased a scooter for city riding and find that's my go to ride for congested traffic.
