Cylinder head Fast Arrow 40.00mm (49cc)

Nice, neat aluminium cylinder head produced based on the original cylinder head. Marketed by the brand Fast Arrow.

This cylinder head has a compression chamber with a diameter of 40.00mm and is therefore suitable for any 49,00cc cylinder.

The cylinder head is delivered standard without the decompression set. If you would like to order the decompression set as shown in the example photos.

Then make your choice in the selection box. 

Do you still have an original decompression set? It fits on this cylinder head. 

Attention! The decompression set is supplied LOOSE, you must install it yourself.

Notes: This cylinder head is of very solid quality, however there are two minor drawbacks we find worth mentioning. The first is that the decompression passage is not provided with a heat-resistant O-ring that seals the valve stem. As a result, when using the decompression lever some mixture can leak out and you may have to clean the cylinder head an extra time. The second is that the height of the bolt passages is 3 a 4 mm lower than the original cylinder heads. You will therefore need to place a few washers under the head of the cylinder bolts to be able to tighten the cylinder and cylinder head properly. If you work with fixed cilindertapeinden you will not have this problem.
