Re: hello all, from Kentucky
hey eDJ, thanks for the welcome. what you said makes sense, at 49cc prolly not the same torque stress as the case with bigger bores. another thing i noticed is that just a little off-centering of the wheel sprocket amplifies the stress on the mounts. i made a little centering tool like they use to install transmission pumps on certain ford trannys. maybe the single most important step for longetivity is to get it perfect.
