Mine doesn't stall, so at least I don't have that to deal with. Anyway, I tried some various settings. Here's a summary. 23Mar13. Tried several MAPS today. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o> 6-222. PowerMap2. Too snappy/abrupt. This one gets a D+<o></o> 2-222. Traction/Enduro Map1. Less power, smooth delivery, runs out of power at RPM, good down low. 28miles/.93gal=30mpg. C-<o></o> 4-222. TorqueMap1. Good power, soft throttle. 25mi/0.75g=33mpg. B<o></o> 0-555. Standard R Enduro Map. OK power, slightly abrupt throttle. 25mi/.70g=35.7mpg. C+<o></o> I can smell the rich exhaust in my clothes after the above miles. Need to try 4-111 or even 4-112 where 2 is for Hi or Carby Main Jet. Wish I had access to a sniffer to see how lean/rich I'm getting. But the poor mileage and the smell tell me I'm still rich.
