hi guys just a quick question for you honda experts
 i bought a sandcast/ko(circa 1970) oil tank from the states the other week it came with a stainless steel filler cap same as they all have,the only thing about this one is there is no actual dipstick riveted to the inside of the cap and looks like it never has been, on closer inspection it only had one breather hole in the middle not the four that i have always seen ok i thought this must be off another honda model , but at this monent in time , i cant think of another honda model that had a seperate oil tank except cb750's ,so if anybody knows what model honda this came off,and put my mind at rest,im thinking possibly 750 auto but really im stumped ,im presumeing all sancasts/k0's came with a dipstick
