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.

This set looks very good. It is packaged in an aesthetically pleasing box and solidly protected with foil and styrofoam. It will be possible to judge the quality of the materials only after the engine is mounted and running. So far I have noticed a considerable (but acceptable) clearance between the piston and cylinder. The rings seem to meet the standards for clearance. Users have reported problems with cracking pistons - most often this occurred near the pin mount. I hope that this problem has been corrected. Grooves for locking rings seem to be deep enough and with the right (semicircular) profile. On the other hand, the safeties themselves do not inspire confidence. If the quality of the materials and the accuracy of the machining resulting in reliable engine operation will match the appearance, I will be delighted.

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.

I've been 'chatting' about a cylinder and piston for a long time. These were the only parts I was missing to fully complete the parts for my Junak. A new, professionally made part, and a super price. Waiting for installation in my motorcycle. I will definitely come back to you!

Junak M10 from 1963 I bought a set of cylinder, piston, rings, pin, protections. Complete set, no shortcomings, does not deviate from the original. 100% satisfaction you install and ride, I recommend to everyone. Regards.

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 :/
