Thread reduction used to repair the Romet head, fits most of the communist vehicles, it is easy to repair the damaged head yourself, all you need is a drill and a threader of the right size.

I highly recommend this cylinder pin, I needed it for my 2002 cobra Avanti moped with a 49cc engine. The pin came very quickly and I immediately saw what I wanted and saw in the preview photo. It is made of very strong material and the threads are very good without any untightening and (which surprised me, because in the past several times I ordered pins from other stores they were slightly crooked), and here to my surprise straight. The product was very much to my liking and my needs, it has been almost a year since the user of the pins and nothing happens to them, they perform their due function. If anyone ever needed such pins it must be these!

The ideal thing in a difficult situation when the thread of the plug is already leaking or completely broken. Without having to look for a new head (sometimes unobtainable or at a horrendous price) even in the garage having a stand drill you can repair the damage and continue to enjoy your oldtimer.

The overall performance of the cylinder is very good. The only shortcoming I found was the sill between the cylinder sleeve and the intake channel. Fortunately, it was possible to smooth it out. After lapping everything was ok, the engine runs properly.

I am satisfied with this product and more so with the service because at my request to pack the package well, it was packed very well so that if the shipment had been in VERY difficult conditions nothing would have happened to it.

The thread should be all the way to the end , because it sticks out a lot beyond the outline of the head in the Dezamet engine and as in the Simson S51 engine. You have to grind a lot , but then the thread is too small to screw in. I do not recommend :/
