Hi, I need some advice. My 2010 K1300S has 72000KM and I love the bike and had no issues. Then last month my quick shifter started to fail 80% of the time. Ok so I shifted manually. Then on same day, as I go up the gears the engine would cut out as I accelerated (note never stalls on idle) . This just got worse over the last few rides and the strange thing is that its ok in 6th gear (link to shifter ??). It happens all over the RPM range, just cuts out/bucks for a half a second - then on - then bucks and then runs ok for a few minutes. Very annoying. I thought it could be the gas, but I have filled the tank a few times already with the highest octane. I thought maybe the plugs, but I don't see / shake when I idle it or rev it in neutral. All well in 6th but i cant drive it like this. Any help would be appreciated.
