This kit is very useful for overhauling FMB139 and related engines . Finally I have new screws, and do not have to look for anything . All that were scratched or machined I replaced with new ones . Now it is completely different . :D
Screws very good quality, after several screwing and unscrewing almost zero trace that they were moved.
The only thing I miss is some sort of sorting or description of which screw where, you have to think either by eye or look in the engine diagram.
A set of screws perfectly matched in length as well as quantity.
It is not the worst grade of steel what you can see because tightening. The heads of the screws even when tightened firmly look intact.
Bought, installed, works, what more to want. The purchase has met my expectations in every way. If I buy from gmoto then I know that it will certainly fit fo my scooter.
