Ours are finding it also more difficult but they get there the second time without fail. I can only bring it down to the lack of oxigen in the air. I know FI adjusts the fuel jet based on this reading, but that doesnt mean less oxigen means its not tougher. Its a very small opening on the air box nozzle. Thats why unifilter dont do a pre_filter. Some guys cut a section out of it to improve performance. Have a look in the F650 faq for it.
We just crossed paso de jama (4832m) without any problems but in Salta my bike wouldnt start untill I removed the nozzle after being parked for 2 days. No problem since but it is working harder for everything now. Including starting.
Is the filter clean?
