Krystian

Timing chain for junk, of course, as for me a very good quality I compared with another chain purchased and the bending of the chain is greater evidenced by a different metal alloy which will cause stretching faster at a later time

The kicker fits very well at the Loncin 125 139FMB engine and does not jump on the polygon. Very easy to install and remove. The quality is very good. I recommend

Hi, I have an atypical moped sachs madass with 139fmb engine ordered a set of cylinder + head 72 4T 139FMB the order itself with shipment went very smoothly, cylinder ok unfortunately the head was no longer 100% as it should be, mainly it's about the finish sharp edges with numerous flecks after treatment, in addition the casting probably from beer cans as for me the head itself is not worth anything better to put money and buy something better quality

i have a 2007 kingway 50 chopper timing chain is made of very good quality material and perfectly matched because some chains seem to also have these 82 links but they are different sizes than on this chain from the motorcycle and this chain has perfectly the same links as the old one I had in the engine really recommend !!!

The plug fits Chinese 250 engines such as Bashan, loncin etc. the fit is very good as is the durability, previous plugs broke after some time and this one holds. I recommend the product, I could not get it in any automotive store and here it is.

Romet Ogar 202 capacity of 49 cubic cyntimeters , manufactured in 2017 . Purchased plug made of medium quality materials for a good price , no doubt a plus is the included washer which they did not have to look for separately .

The engine is great, unfortunately I wanted a connection plan and a carburetor. Unfortunately, after several emails, I got no response at all. So the engine is great but the information is bad.

Zippa Pro 50 ;) Good quality parts did not cause any problems during assembly. The whole process went quickly and smoothly. In addition, the chrome on the valve adjustment cap improves the aesthetics of the engine.
