So the GY6 that's currently in my Yerf Dog is coming out (cracked case, ground up gearbox) and I will be replacing it with a GY6 with built-in reverse. I am anticipating sprocket alignment issues. Can I use a keyed axle to get my sprockets lined up? Would that be strong enough? Where to buy? Can anyone could point me to a build thread where someone's already done this? Thanks in advance for your responses!
