NC-Motorparts 41 mm Cylinder Head Tuning | Sachs 50/3, 50/4 LKH

EUR 118.80

Incl. 25% VAT.

Description

41 mm cylinder head for 3- and 4-speed Sachs mopeds, motorcycles, and small motorcycles with 50/3 and 50/4 engines equipped with the large cylinder.
The tuning cylinder head can be used when converting to air-cooling.

The increased compression in the combustion chamber results in a noticeable increase in power.
The tuning cylinder head does not have a decompression port.

Ø External cooling fins: 128 mm

Note: Does not fit standard “small” fan cowls. Additionally, spark plugs with long threads are required.

You can find compatible components such as spark plugs, cylinder head gaskets, silent blocks, etc., in the accessories section.
