Description

ATTENTION: Requires crankshaft with connecting rod 110

Diameter 63 mm Stroke 60 mm
Meteor piston
CNC head machined from solid
High performance cylinder.

The most suitable diagram phases to have the best performance and reliability are:

Secondary transfers: 120

To have these phases, a 1.25 / 1.3 mm gasket / base pack at the base of the cylinder is generally sufficient
Lowering the air gap / squish to 1 mm (approximately) to increase the low torque is possible, but requires further attention in the control of the ignition values ​​(24 if variable acc.) And carburetion (richer in the throttled)
Diameter 63 mm Stroke 60 mm
Requires crankshaft with connecting rod 110
