capuchin the reason Jake’s looks different is because mine has the full Daniel Wong kit on in comparison to Jake’s which has original mazzer forks. The lever adjustment is literally just a screw with a rubber handle and comes with different variations I just swapped mine out . If you Google the Wong kit you’ll see it’s about 180 dollars itself + shipping and any duties. With regards to the motor these things are virtually bullet proof, but there’s not much I could say to reassure you with regards to it’s lifespan. You might be better buying new if your worried about the lifespan of the motor, and maybe consider something like the niche?
