Hey all. Finally got my bike finished except for playing with AFR's in my powercommander/autotune combination, and maybe giving it a wash and polish for photos . 2009 Triumph Sprint ST 1050, with a K&N filter and a baffleless staintune system... (and a sheetload of at this time irrelevant mods!). Any tips for AFR settings with that sort of a combo?? Or am i just going to have to experiment? I am planning on starting out with AFR of 13:1 and fiddling from there. I expect to be able to run a little richer with a freer flowing system, reasonable assumption or no?
