Front Sprocket Sleeve To Convert 3 Speed J + Luna Line Lambrettas to 4 or 5 speed Summary
Special front sprocket sleeve to convert 3 speed J Range + Luna Line Lambretta models (Lui 50 + J50 + Cento + J125) to 4 or Vega5 5-speed!
This sleeve is a different height to the similar sleeve M350. The reason for this is that this sleeve is needed if you intend to take an engine casing that was originally 3-speed, and then convert it to 4 or 5 speed. This special sleeve enables you to get the right chain alignment height between the front sprocket and the clutch crownwheel bell.
This is the complete list of all possible front drive sprocket & clutch crownwheel sprocket combinations for all J-Range and Lui-Vega-Cometa models, complete with the required length chain
