Did my 24k service last weekend including throttle body sync. Idle is much improved as is throttle response. Since I did not have the Triumph digital vac tool or a mercury column, I used a UniSyn tool from my old VW Weber carb days. The UniSyn is placed over each throttle body opening individually (cap off the vac ports used with merc column ) and a floating pill measures base idle air flow by rising in a small glass tube. Get the pill to rise the same for each throttle and your there. Worked for me.
