How often should i change my clutch?

it is not a car, so moved you to correct"? R6 forum.
no full model told , year yes.
nobody buys MC parts from amazon, and get wrong or worse used or even cloned junk from 12,000 miles away . pure junk.
buy only top brands and new.
wrote it mean road it? not road tested?
yes there is a trick and that called skills and reading the service manual, and using legit parts, not CCP cloned junk. for sure used.
is this a cable clutch or MC/slave hydraulic, actuated clutch
no full motorcycle model name told R6 is not it sorry not. YZF-R6?
the CLUTCH hub and disk/steels packs put in correctly and torqued to spec. the linkage installed correctly , it is not a trick but a skill set to know that, called experience or read he shop manual and not guess. is 2nd way.
then the lever left bar actuator is adjusted.

YZF-R6
600cc class?
with (anti de-accel compression braking for racing)
and a multi-plate slipper clutch
with cable adjustments
the acid test (key off)
put 6 speed box in 1st gear. by hand.
Do not pull in the clutch lever, bike must not move. or rear wheel drags. then do pull it and bike moves.
if moves clutch in or out, bad
if bike moves clutch in that 9s good.
or not move at all, in gear lever pulled, bad clutch.
that means bad clutch or bad cable adjustment or the linkage
at engine clutch the actuators parts put in wrong.
if test shows, bike does move, clutch out and lever not touched
that means clutch pack bad or wrong.parts or missing disks.
next.
so remove clutch cable now, (bike most not move)
and if wheel Rear is locked (good) pushed that means cable was adjusted wrong or bad linkages in clutch actual.
best is RTM get the service manual and read it for this job.
Or ask bike guy for help, a living person to show you this job.
many owners or racers all DIY this.

three things must work here.
cable not bad or wrong. or rusty jammed.
cable adjusted correctly at both ends.
clutch links good inside clutch casing.
clutch packs all good, no slip and no jam ups and no cloned parts ever. buy from Yamaha only if confused.
on junk parts sold all over the planet.
some old clutch packs the main clutch cage
the fingers there a wreck, we inspect all and if is , the clutch will be pure h3ll use, jamming up at random. no damage on machined surfaces, we look.

It is called a "Clutch Cable" You just take the old one off and put the new one on. Simples

THE OPERATION OF THE CLUTH ON HIS MODEL IS OF CABLE TYPE, IF THE CLUTCH IS OPPERATING CORRECTLY THE 1ST THING TO CHECK WOULD BE THE CABLE, REMOVE THE CABLE YOU SHOULD BE ABLE TO PULL THE INNER WIRE SMOOTHLY TO AND FRO, IF YOU NEED TO USE ALOT OF EFORT TO DO THIS THEN YOU WILL NEED TO REPLACE THE CABLE,MAKING SURE YOU HAVE ADEQUIT FREE PLAY AT THE LEVER WHEN RE FITTED. OBSERVE THE ROUTE THE CABLE TAKES BEFORE REMOVAL AND REPLACE IN THE SAME WAY, YOU MAY ALSO TRY TO GET SOME LITE OIL DOWN THE CABLE, THOUGH I SUSPECT THIS WILL BE ALMOST INPOSSIBLE IF IT IS THIS TIGHT TO OPPERATE

I wonder if maybe the kickstand switch is bad letting the bike think the kickstand is down. When you let out the clutch it shuts of the engine as if the kickstand is actually down.

Loosen up cable and clamps, then squeeze lever, pull back cable and unscrew and detach
