Broke off when tightening. Do not overtighten, if manual says 40 Nm do not tighten to spec. The magnet goes all the way down the bolt so there is very little material holding the head in place. Looked nice before the head fell on the floor though

I have been buying parts from gmoto for several years and I am very satisfied with the quality of the product, as it is made very solidly and aesthetically pleasing. The shaft protector that I recently bought fits perfectly to my 139qmb 4T engine

It's OK. Suitable for Kymco agility without problems. Otherwise just a standard aluminium cover - use half the official torque, exhaust manifold bolts preferably 5 Nm tighter than the recommended torque, etc.

The head is perfect.Very good quality workmanship.Hassle free installation .One note, it would be good if the valves were lapped.I am not attaching a picture as I would have to take the scooter apart

Zumico Quick 4t 50ccm. The set fit perfectly, the only remark is that the set was missing the bushing seen in the photo, which I replaced with the old one. Overall I recommend :)
