F800GS Piston replacement

The video above is the sound which my BMW F800GS engine started making. It started out “not as noticeable” but as time went by it became worse and worse. I had the bike at 2 BMW dealers (Vines Guildford and SBW) who told me it sounds normal. The problem was, that when the engine gets warm, the sound subsided, so by the time I got to the dealers I was given the “sounds normal” speech.

I ended up taking my motorcycle to my local dealer, BMW Battersea London, which would you believe it or not, were the most helpful. I have asked them to keep the bike overnight and listen to it the next morning when the engine is cold. I received a call the following day to tell me it doesn’t sound good, but they are not sure what is causing it.

They have consulted BMW Technical in Germany who asked them to strip the whole engine and find the fault. So they did and found worn pistons and bearings. They did a complete engine rebuilt, new pistons and parts all free of charge to me at least. I also recently went back for my “600 mile run in check” again which was done completely free of charge. I have to say a thank you to Veronika, Joe and the team at Battersea for all the help, they have really been very helpful !

All sorted now and the bike feels good !
