JMP magnetic oil drain bolt M12x1.50 mm long 15 mm aluminum Racing gold

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

Foot starter shaft protection 139 QMB 101 Octane

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
