Replace the hard to get to stock slotted or “D” shaped screws with our custom made Idle Mixture Thumbscrews.  Unlike other thumbscrews on the market, our screws are EXACT replicas of the stock screw’s needle taper and length.  This allows the years of knowledge gained from the Triumph community to apply directly to these screws.  What does this mean?  3 turns out on the stock screws equals 3 turns out with these!

The knurled head is scored at 180 degrees for a clear, easy to see indicator.  The heads are machined out to reduce weight and vibration susceptibility.

Fits all years carbureted Triumph Bonneville, T100, Thruxton, Scrambler, America and Speedmaster
