We are currently in Trujillo, Peru having trouble with both of our F800GSs. We were driving on the highway and both our bikes felt underpowered. There was also a weird ticking noise on hard throttle openings (like passing a truck). We had recently filled up with gas in a small town so we thought that maybe the gas was bad. We were in the middle of the desert so we put our spare (presumably good) gas into the tanks to try and dilute the bad gas. This seemed to improve the situation a bit but it did not fix it. We got the bikes to a safe location where we are currently staying.
the bikes sound terrible and now stall or have troubles starting. We checked the air filter and in the compartment there was a bit of oil. We cleaned that up and replaced the air filter. the bikes still sound terrible and the oil has returned after taking the bike for a short spin.
As far as we know there is no BMW dealer in Peru and we are worried about driving our bikes anywhere and doing further damage. We are also worried about letting some random mechanic here start stripping the bikes if the problem runs deep. No warning lights are on and both bikes are acting up in similar ways. Any ideas?
Summary of issues:
Oil in air box
difficult to start
Generally sounding like sh*t
