can anyone tell me why the scott rad” has domes on the header tank ,I’m trying to build my own brass rad” and I can”t for the life of me figure out why these domes are there apart from appearances? I would also like to know if there is a four speed gearbox available to suit a 49′ fl.squirrell? as 1st gear seems too high and top gear seems to overrev the engine just to keep a steady 60 m.p.h. I’ve tried fitting a 24 t, outrigger cog but that made 1st gear almost impossible to take off, fearing I would burn out the clutch, I quickly put the 22t back on, any advice would be welcome. Midge.
Maybe to stop the effects of heat distortion, which you get on square structures
