Re: [ST] Latest Tune Question/Lane Splitting

[jhseltzer <jhseltzer@xxxxxxxxx>]

The driveability problem you describe is caused by a lean 
mixture or too little fuel at idle and in the lower rpm 
ranges.  My 2000 ST had the same problem and the dealer was 
unable to fix it. You may be aware that Triumph requires the 
dealers to purchase a Gunison carbon monoxide (CO) monitor. 
They are supposed to adjust the idle mixture whenever they 
install a new tune. To make a long story short. My bike was 
a pain in the ass for about 12 months. I finally bought a 
Techlusion FI adjuster and using my own Gunison meter 
adjusted the CO at idle to 3%. My ST runs great now. Come to 
find out my dealer's Gunison is off by 1.5%.
