Hi,
I know that special 5hp versions of the BS100 were sold in some states of the US (presumably to comply with local licensing regualtions), but I have always been puzzled as to what modifications were made to the se engines to reduce their power output. Does anyone out there know the answer?
I've checked various parts books and dealer price lists, and there seems to be no indication of likely special parts for the BS100. I'm not planning to detune my 100TMX to 5hp, though - I'm just curious.
