AFAIK chain tension is within specs, but how sensitive is the QS and chain tension? I need to get one of those chain alignment checking rod tool things now I think of it...
I recently fitted the HP levers, but issue was existing with the factory levers (no worse, no better) - microswitches working fine btw, cruise control is working fine and QS in other gears is almost flawless. I also try to avoid using the QS if rpm is less than ~4000rpm.
Clutch cable is good, I have ~1-2mm free play, when cold, at the lever pivot point which I believe is within specs? Also approximately matches what the OEM lever had and it recently has its annual service.
When the bike is hot however, the free play is quite a lot more...roughly 5mm or more...???
Bike has ~9000km (~5600 miles).
Re force required; It was a bit of a learning curve, being first bike with QS, but I've found I have to 'push' the shifter with a bit of force, rather than tap it like I would on an older bike if I was doing a clutchless shift for example.
1st to 2nd, and vice versa, definitely needs a stronger input, more than the other gears, which I put down to things I no nothing about! gearbox design/arrangement, something to do with protecting from hitting neutral accidentally, and so on...but I'm hitting too many neutrals and in some scary moments which prompted this thread.
I might have a go at resetting the QS on a paddock stand like mentioned and see how that goes. Failing that it might be best to take into BMW and get them to have a looksee. Hard to replicate though so I can see where that visit will likely head
