Drive chain suggestions

Will be using a sturmy archer 3 speed gear hub with drum brake on my build.
Does anyone have suggestions as to which chain would work best with that set up? Will be running a 4 stroke kit engine with a sbp jackshaft kit. Was thinking that a good heavy duty bmx type chain available at my LBS would be a good choice as it will probably work with the sprocket on the gear hub and with the sprocket on the jackshaft. Btw, my work stand is in the mail and should be here soon. Will post my impressions of its quality when i get it.

Nice setups man, do you sell just the wheels? Looking forna 3 speed or 5 speed drum for the rear with a drum for the front. Heavy duty spokes 12 0r 11 ga. Do you ship complete builds? But to be clear, the kmc 415 works for the drive chain from the front sprocket to the gear hub sprocket?
