Not down shifting

[Marcvander]

Good day all,

Tried searching for this but could not find anything….

Quick shifter works fine on up shifting, but will not down shift.
Anyone have any ideas?

Appreciate any help.

Also check chain tension, blipper doesn't like it if too loose

Thank you for the comments….

my bike is a 2018.
Micro switches are fine, first thing I checked
Plug is secure.
Drive chain is as per spec.
Look forward to further advice

If all other things are good...and it works on the upshift and not the downshift, I suspect your shift pressure/tension sensor is not well. Plugging into Motoscan or a GS-911 and looking at live data may show some insight. I've not seen one fail though....but sillier things have happened.

Thanks guys, 

I don’t have a Hex GS911 so will book it in with the agents for a check.

Throttle closed?

Basic but good point, worth mentioning..

in all honestly it still works with a slightly open throttle as long as you're decelerating

Throttle closed, even tried different ride modes in the hope that it might make a difference
