Azusa Mini-Bike Frame

Can anyone tell me what the weight capacity for this frame might be? I'm looking for a manufactured frame that can handle an occasional 250 lb. adult.
I am a 230 pounder, never had any probles with my Azusa frame deforming or bending. But, yea, the word minibike has the name "mini" in is so it is supposed to be small. Minibikes are intended for kids. If you are a 400 LB "El Blotto Maxo" even a 350 LB'er you may just be too big for a minibike, but, yeah, the Azusa frame is well made and can take a beating. Attaches is my Azusa with the old Harbor Freight engine, now a classic Briggs 5 HP, even older.
