Metalhead has given me a set of konis from a cb450. will they phiscally bolt up to my 750 and how much shorter are they? i've come to the realization that with the stock seat on my 74 750k, i have to lower the thing so i can touch both feet at once (that damn 29" inseam attacks again). please dont tell me get rid of the seat, with new foam and new cover. this is the first time i have had the stock seat (except for the 1/2 mile i rode it the day i got it, before being broadsided by a soccer mom on her cellphone, since then i have always had cafe seats.
