Cylinder kit -UNI AUTO 175 ccm- Lambretta li, SX, DL, GP

UNI Auto Lambretta cylinder with 62 mm bore and piston with 39 mm compression height. This allows all original 125 cc and 150 cc Lambrettas of the Li family to be upgraded to 175 cc displacement.
Series 1 and early Series 2 have shorter cylinders. It is best to order a new cylinder cover at the same time.

If you want to do the work, you can adjust the cylinder timing. For a fast touring engine, you should aim for 165-175° exhaust timing, 123-126° overflow timing and 140-145° intake timing. In terms of carburetors, an SH 22 up to a 28 or 30-barrel carburetor will serve you well. The bgm PRO Big Box Clubman exhaust is recommended for touring. _{AI-translation}
