Sixty-three millimetres of bare exhaust spring. The shorter of Spark's two, for joints where the hooks sit close together.
Key Features
- Exhaust spring, 63 mm.
- Supplied without a rubber sleeve.
- Spark part number MOLLA02, made in Mantova, Italy.
Sixty-Three or Eighty-Three
The choice is set by the distance between the two hooks once the joint is assembled, not by the diameter of the pipe. A short spring stretched to its limit loses most of its pull; a long one hanging slack does nothing at all.
Assemble the joint dry, measure between hook centres, and pick the spring that will sit under real tension.
Where the Short One Goes
Tight positions: a silencer clamped close to its bracket, a link joint with limited space around it, or any place where an eighty-three would foul the frame when the joint moves.
Fitting Them
A spring hook or a length of stiff wire with a bend in the end. Pull the spring, do not lever it against the pipe — a slipped tool marks stainless permanently and it is always on the visible side.
The Sleeved Version
MOLLA07 is this spring with a rubber sleeve, one euro more. The sleeve silences the metallic buzz a bare spring makes against a hot pipe at idle.
