Oh Yeah,I remember those Bighorns. I rode one once that had the factory kit on it,it ran pretty darn well.
I gave a guy a ride to a TT race one time,it was his first race and he was riding a stripped Bighorn. He smoked the novice class to the point where it was ridiculous,coulda been in the hunt with the amateur/expert class.
Next time he raced was on a fully sponsored Bultaco.
Buying that one you got already settup like that sure saves a lotta work and money.
Some bikes around at times
