Tune-up of xjr400r? - 2002 Yamaha XJR 400 R

Good question, tuners can be simple and some are complicated
a basic automatic guitar tuner you would not have to do anything to the settings, just tune normal on the E string then slowly down tune to D most tuners are a little sensitive, so go slow
and one thing I always do is go lower than the note I'm tuning to then tune up tell it's correct, strings seem to stay in tune better
Hope this helps ?
and if you have time check back on my profile
I will be doing some video tips this weekend
showing tuning, and some basic guitar repairs
thanks for your time

put a battery in your guitar. It goes in the space at the bottom, usually where you connect your cable to your amp.
Then hold the guitar as you usually would.
Look for a little board with buttons on the side of the guitar to turn on the tuner: )

it's not failing to tune, it shutting off as tuned. 1.25:1 is below it's threshold to tune

You need to study or research info on tune-ups
Basically it is a sales pitch, as only spark plugs are left
