I have a 1998 SID, and one leg is loosing air at the air plug valve. (at the top)
The 98 uses an air valve system just like a basketball.
So i need a new air plug, which is just a little cylindrical rubber thingy.
Anyone know where I can find one, or some DIY method like using some rubber from a rubber ducky ?
If I don't find a air plug, I'm thinking about drilling the top cap, and insert a auto valve, and making it stick and not loose air.
The simplest method would getting some air plugs with classic air valves from a later SID.
But cant find any in my area.
