I have a YZ450F 2011 the bike sometimes falls out under load I did a reading with the diagnostic tool and it told me D61 fault code 30. This is the lean angle sensor and it's in the ECU so I replaced the ECU and still the same problem. I checked all connections they are all oke. The problem is the bike runs great but sometimes and you never know when the engine stops, I had it on a jump face, and sometimes after a landing sometimes during acceleration it's always a surprise. Did anyone have this problem and found out what the solution is?
