BMW R1200GS/GSA "pinging" leading to possible Engine Failure!
We are trying to obtain as much info as possible from 1200 GS/GSA riders all over the World, but more specifically in the Southern Hemisphere countries.
Our 2009 GSA's have been found to run incredibly lean with an Air/Fuel ratio of 14.7:1, which together with our poor fuel in South Africa and high temperatures are causing the bikes to constantly "ping" and the overheating to the point where we have to switch the bikes off.
A group of 20 GS/GSA/HP2's and one RT were tested in a controlled environment on a Dyno and at 24deg C, we found that the worse of the lot was the RT with a 15:1 ratio.
We have been told by BMW that these are the settings to comply with the EU Regulations, but Germany and Europe specifically might as well be another world... we have temperatures up to 47 degrees.
Planning a trip through Africa is going to be near impossible due to the poor fuel.
There have been a couple of Boxer engines self-destructing due to the high heat caused by excessively hot running conditions, helped along by extreme temps in the engines with lean mixtures.
We have a huge lot of research behind the belt and want to present our findings to BMW to get them to allow the mixture mapping to be changed on our bikes to the idea of 13.5:1, which would not only allow a better and more responsive engine use, but would also prevent damage and melting of pistons and valves.
Anyone interested can please check our thread and findings as well as comments that are now rolling in from all over as to the "pinging" condition of these wonderful machines!
Any and all advice, help and info would be gratefully received to assist in resolving the issue!
