I have a yamaha f115 , never had any trouble with it and has been serviced. This season i realised that on the higher revs it is giving error code 49, with no other effects. still works perfectly. But the code is kind of enoying. Checked the code in the trouble shooting it states "Ignition timing is being slightly corrected (when starting a cold engine)" Any idea what can be done or what is at fault? P.s. the fault comes up even if the engine would have been running for quite a long time -warn-
