Timing chain 82 links 4T 139FMB

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

Head cap left lower 4T 139FMB 154FMI 156FMI 162FMJ

The stopper is well made. Quality at a high level. Very well coated with chrome, does not come off and is very aesthetically pleasing. Holds firmly in place. I recommend this store to all motorcyclists.

Oil O-rings cylinder - head 4T 139FMB 154FMI

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

Artur

Electric Starter Chain 4T 139FMB 154FMI

The chain, after lubrication with oil-protection against rust and installation, has not caused the slightest problem. Since its purchase- that is, since the previous motorcycle season 2023- it has served without the slightest complaint. I am a person who rides daily- to high school, now and to work. Honestly? As if I had to recommend, for this price, the product as highly recommendable.

Timing chain 82 links 4T 139FMB

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 !!!

Oil drain plug 4T 139FMB 154FMI

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 .
