Oh, I didn't know they weren't compatible. I have an older motor so I don't think it has the bearing. All I know is that piston moves around like a bobble head, lol.
Looks like Spooky only has the top end for the 60cc, which isn't the same size as my 70cc.
Thanks for the zoombicycles tip, I'm going to order from there. $95 ain't bad...Dax sells the motors for like $150..might as well just buy the whole kit, lol. Also, I know it doesn't mean I have to ditch the MB, but I'd like to spend less on the motorized bicycle and save more for a mc
