I'm new to all motorized bicycles.When in fact Ive not owned one.Since I love building mechanical things.And working on and building engines.This engine powerd bicycle issue keeps coming to mind.However, this is the big question.After I had researched different issues came to surface!For my wanting to use a zenoha over any china made engine.That starts and ends with high quality.From anything you get from japan.Which can not be said or read in most that comes from china.I said most not all or everything.Depends upon what it is and whos name is on it.This is about one thing only.That is used to power a bicycle. Which I'm anything but stupid when it comes to engines and just about anything that goes into building a engine .Not that Ive built any from raw materials.I don't have to when I understand whats right from most wrong.Fast proven by why Id use a japan brand engine of any type before at all using any from china.However, I don't know exactly what all this will take.In terms of money or parts required to build one right.When the one thing I am into is owning only whats been built sanitary.For my meaning of clean and done right.However that words comes typicaly at some price.So please I'm all eyes for wanting to read what those of you with hands on experience with this G62 engine have to say.For anything at all please do tell me.Cost build and performance.
