Just wondering if anyone out there has tested or played around with the fuel maps, and what was the major differences they found and when. I been riding mine long enough now with the standard one so have a good idea now how it goes in different conditions, especially sand. So ive put the rich map in ( the grey one ) in for a sandy MX track this weekend. Hoping it will give it a little more peep on the wide open stuff. will post again once ive tried it. Keen to hear from someone how the lean one compares to the standard.
