fcr jetting with E10 gasahol

in my part of the world i only have access to E10 or gasahol as it is known here. does anybody have any experience or changed there jetting slightly to suit. my fcr feels like it is running very rich and runs worse as altitude increases.


open muffler

k&n air filter


155 main

emn needle 3rd clip

45 pilot jet

100 pilot air jet

r&d flex jet 2.5 turns out

starts to run quite rough and pops alot once i get over 1000metres in altitude

Most of the fuel sold n the US is E10. All the jetting you see posted is for E10.
