Engine switch off in 1st gear

[maria41]

Hi everyone!

Had few problems on my 650GS yesterday and wanted to know if someone experienced this!
For about 30 mins the engine would just switch off when I was in 1st gear and starting to brake. I stopped for about 15 mins and the problem did not reappear after that. The bike starts ok so can’t be a battery problem.
Later on in the afternoon, on the motorway, I was riding at 80mph and on 5th gear when I heard a nasty noise and suddenly the throttle would not respond, i.e. I was losing speed very fast . I managed to make my way to the emergency lane and stop there. The RPM clock was showing >8000 and in the red, I was surprised because by then I was stationary with the engine in neutral and not raving and to be precise I did not rave up the engine to reach 8000rpm at anytime!! After a few minutes I started the bike again and managed to make my way home slowly ( I did not dare to get into 5th gear in case something is broken there as I had problems to go down form 5th when prob occurred and had another nasty noise going down to 1st gear!).
So my question is, anyone had probs like that? Are the 2 issues related? After about 15/20 mins the RPM went back to normal (btwn 2000 and 4000ish rpm) and I got home ok without any other problem with the bike!

This sounds very much like an electrical fault. The first step would be to check the wiring of the bike visually. Make sure you dont have any frayed/naked cables. Try WD40 on any exposed connectors. If you are stationary and your put 1st in and it cutss out it may be an indication that you have a faulty sidestand switch.

When my battery was on the way out, the speedo and rpm would shoot up high when starting up, make sure you have good connections at the battery end.

Hope this helps

Engine switch off

I thought I would put an update for anyone who may experience the same thing. The problem worsened an I had the engine cut off suddenly on the motorway at big speed (nearly gave me a heart attack!) . Anyway, I took it to BMW Guilford and it seems it is related to a software problem. They uploaded a new version into the bike computer and can't testify if it is ok as I have not picked up the bike yet!
