In case you want to know, the Triumph idle mixture service tool is T3880089. Earlier models may use tool 3880015-T0301. (Whatever "earlier" means, I do not know.)
The dealer cost and retail for the first is $32 and $55, respectively. Dealer cost and retail for the second is $150 and $251, respectively.
Or, you can buy one from Brent for $17.
