Yes... the F800GS can be remapped!

Correct. We took delivery of the bikes with the lower octane mapping. We've been putting in 87 ever since.

Anyways, we've just spent the day at BMW in Lima. They looked at Alberto's bike (since it was the sickest) and the good news is it wasn't bad fuel, the bad news is it wasn't bad fuel and is most likely a more serious issue.

At least we made it out of the highlands and to a BMW dealer in Lima without any major issues. Props to the dealer in Lima. They have been super helpful all day. Their one mechanic went straight to work on our bikes and was troubleshooting all day. Our bikes are now in their capable hands and we are playing the waiting game. The true cause of the problem is still unknown

The unlikely seems to have happened. a mechanical failure on both bikes at around the same time (different mileage, same riding conditions).

We'll keep you posted!

Same problem, at the same time, on two separate bikes? This one would go down in the history books......

Tell me about it.

Changed the fuel. Changed the oil.. no change. What else is common between the 2 bikes that's changed recently?

Well, in all fairness they have been ridden side by side, in the same environment for quite a few miles now. Outside influences affecting one would be quite likely to have had the same effect on the other...


Pinging, low power, stalling. I'd be looking into valve & ignition timing, and lean running as the most likely suspects. Excessively high operating temps can also have that result somtimes, but I'd think you'd have noticed it was overheating. A plugged exhaust doesn't usually cause strange engine noises, but also matches your other symptoms.

I hope they sort it out for you guys so you can get back on the road, I've really been enjoying the blog, and the photots!

Thumbs down surprising, disappointing, upsetting

Just got back from Gildermeister (BMW dealer in Lima) and got some bad news to share. In brief, my bike has broken piston rings and various engine components are unusually worn-out (gaskets, metal rings, etc, too many to remember ). Naomi's bike is being dissected and so far they are finding similar issues.

They don't know what exactly could have caused such a catastrophic failure on BOTH bikes. Bad gas can't do such damage according to some of the BMW people here, others think it can. If you ask me, as an engineer I don't think bad gas can cause such failure. All the data is being forwarded to BMW in Germany and they are 'analyzing' the data, photos, reports to know what to do with the bikes (what parts to replace, or even if we should get new engines). It is still being decided if this is covered under warranty (WE HOPE!) or not...

Another possible cause of this mess is bad lubrication (either very low engine oil levels, which is not the case as I checked the oil level regularly, a defective oil pump or just poor quality oil (last time we changed the oil was at the BMW dealer Ruta40 in Medellin, Colombia and they use ELF MOTO 4HP ECO 10w40).

Or just simply a factory defect on both bikes (both bikes were bought brand new and were ordered at the same time; same batch)

Bottom line, we're not going anywhere for at least 4 weeks. And if this is not covered under warranty (which would be even more surprising) we wouldn't have the economic means to continue our travels.

Well.... what can I say... If I ever thought something was going to prevent us from continuing our trip was my herniated discs/compressed spinal cord but not our brand new 2010 BMW F800GS...

Surprising, disappointing, upsetting

Alberto

Some pictures for illustration:

If you've ever seen a piston head/rings it shouldn't look like this one


Part of the oil-pump, see the marks? not good


Piston from my Gringa


bits and pieces being analyzed


Is the dark colour normal? mmmmmm...


No heart, no life.


I literary almost cry when i saw her today


It's Nomi's bike turn to be opened up

These kind of problems can be from
  • oil pump
  • oil itself (low oil viscosity for high outside temperature, canola oil re-branded as Castrol ...)
  • semi-clogged oil canal/hose
  • low level of oil (not applicable because you checked the level)
Hope to be fixed under warranty!

As it happened to both bikes at the same time I suspect that "oils aint oils". Either that or a batch of defective oil pumps!

If this is the case (the oil) you might have a problem with your warranty ... be very nice to BMW and cross your fingers! (they can occassionlly be very good to their customers). Good luck!

I don't see how this could be a problem b/c the last oil change was done at a BMW dealer, before that I changed the oil on both bikes with the recommended (by BMW) castrol oil and OEM BMW oil filters. We shall see I guess.

If it was a cylinder lubrication issue the piston skirt and cylinder would be scored.

No problem then!

ouch!
I think its plausable that this is the result of severe detonation. Its hard to tell from the pics though. How does the top and top edge of the piston look?

As far as waiting 4 weeks for parts from Germany.

If you are willing to do the legwork and I'm pretty sure you now have the time, you could get the part number's and call/ email every BMW dealer between Lima and Vancouver to see if any have the necessary piece's in stock but closer to you. At least you'll be able to put shipping of the parts under your control instead of the factory.

Just remember that excluding customs, everything in the world is no more than 2 days away from any major airport if you're willing to pay the shipping costs.

That being said there are far worse places to be broke down.
