Re: [ST] Latest Tune Question/Lane Splitting

[Colt4530 <colt4530@xxxxxxxxxxx>]

That's EXACTLY my problem.  It's still there, just not as bad.  In fact, 
I told the dealer it didn't do it when cold, but did after it gets over 
about 150 deg.  While it's much better, now, it still surges at cruise 
at or below 2k.

How do you adjust the idle mixture?

These guys have been selling bikes and parts for a long time, but have 
not had Triumph long.  They may still be a bit green.  I'll try to 
figure out how to "help" them.
