Product Description
Venolia +020" piston kit.
1 x piston
2 x rings
1 x gudgeon pin
2 x circlips
Fits:
410 Stormer
Note:
The Venoila pistons were used as a stronger alternative to the Hepolite pistons for the 410 models.
They are stronger but expand more and so will require extra clearance and careful running in.
Clearance should be 0.004" - 0.0045"
Run in for an hour, then strip down and hone off any high spots on the piston.
Silkolene Casterene R40 oil is recommended at 32:1
