Apply Front Brake at Idle: Bike Runs Rough. Any Ideas?

[DrSpencer]

2011 103" Street Glide.

When idling/stopped in traffic, if I apply the front brake, the RPM's fall just a little and the bike runs rough.

When I release the front brake, while staying in a stopped position, the RPM's return to normal and the bike smooths out.

This does not happen when using the rear brake.

I mentioned this to some other riders and got the standard "They all do that."

Any idea what may cause this condition?

Thanks

With or without ABS ?

Good question. Bike is equipped with ABS.

Pull the fuse to disable the ABS to see if it still does it.

Is this your first tourer?

If not and your previous tourer did not do what you describe then you may have a mechanical problem - let dealer check it out.


If this is your first tourer then perhaps you simply need to do this:

At idle, notice that the engine is moving in its rubber mounts but very few vibrations get through to the handlebars and seat. Now look down at the front wheel and axle bolts and you will see them shaking quite violently as the fork and front wheel assembly dissipates the engine vibration.

Now apply the front brake - notice that the front fork and wheel stops shaking. The engine vibrations will now be transferred up the fork and will be strongly felt in the handlebars. Apply and release the front brake a slowly a few times and you will easily feel the transfer of vibrations.

Applying the rear brake at idle has a similar but lesser effect.

If this is what you find then yes, they (tourers) all do this!

'09 and '10 seem to do that, these are both ABS equipped bikes......
RG demo bike did the same thing....
