Re: [ST] Stalling

[Nathan Maher <nate@xxxxxxxxxx>]

Jim,

The stock tune (the one the bike comes with) is on the lean side to help 
the bike pass emissions - my RS had lean/surge issues with the stock tune 
and stock can.  Moving to the carbon can and offroad tune made the bike 
run significantly better.  If you've had the bike worked on since it was 
new it probably doesn't have the original tune anymore, at least it 
shouldn't if your dealer is doing their job right.  Part of the major 
service intervals is to upload the latest tune to the bike.

And you are correct, the CO setting is not user friendly.  I'm almost 
certain it requires specialized equipment.

Hope that helps,

Nate
