VAPE SPORT Variable CDi / HT Electronic unit S.I.P Performance

Vespa or Lambretta VAPE ignition variable timing electronic unit.

S.I.P say.......

'Sport' version that includes a variable ignition point which advances at low revs. This increases the available torque - especially at the lower end - and the ignition point is then gradually retarded as the rpm rises into the power-band. This also helps reduce the combustion temperature while simultaneously providing an increased rev-range. The exact adjustment range is shown in the instructions as a diagram. Between 4000 and 8000 rpm. E.g. adjusts the ignition by 8 degrees towards retarded.
