Lightweight carburettor slide springs

This auction is for a set of 2 lightweight throttle slide and 2 lightweight choke slide springs (4 springs in total).

"Designed to increase riding enjoyment by reducing the handlebar twist grip pressure by virtually half.”

The springs are specifically manufactured for twin (and triple) carburetor concentric equipped classic motorcycles and are not OEM parts.  This includes the Triumph Bonneville, BSA Lightning and Norton Commando, all of which are fitted as standard with AMAL concentric 930 and 932 type carburetors.  Twin concentric carburetored engines such as those fitted to the Triumph Daytona 500, which use the Amal 600 series benefit to an even great extent.

The new springs are designed to reduce the force need to hold the throttle slide open by almost half, while maintaining a pressure of 80% of the original type at idle, when the throttle slide is closed.

For this reason they are not normally recommended for single carburetor installation.

If you have ANY questions then please just ask.  I always leave feedback once I know the goods have arrived.
