Disconnecting Battery?

[Mr K]

I'm about to fit the heated jacket lead {Yeah, I know: Soft as sh**e} to the battery and seem to recall something about having to do something with the throttle twist-grip before starting up, after the battery is reconnected??

Ignition on, twist throttle open fully twice, ignition off, then restart.

Job done

 

[Mr K]

Ta!

Eh?

Didn't have any issues when I fitted my Aux lighting relay. OK, it was only disconnected for a few seconds, so that may have prevented a capacitor having time to drain down, but why are you supposed to twist the grip?

99% sure that is no longer necessary on the new 1200 bikes. Had my battery disconnected several times without doing the throttle dance.

Pretty sure the above applies to Twin-spark 1150's too (I've certainly never done it after disconnecting the battery and it's always been fine).

i believe it only needs doing after a motronic hardware change or resetting of the TPS.

You have to do it so that the brain knows the fully open and fully closed position of the throttle potentiometer ... (or some such thing) doesn't stop the bike running or anything ... just mucks up the fuel injection ...

So that's why I was so feckin' slow today.....

The manual still says it should be done ... for the sake of 10 seconds it doesn't hurt to do it anyway

Mouse,

Can't argue with that logic.
