Actually I have been saying the same to anyone bringing up the subject.
I have a buddy that I sold a sohc 750 that raced it , and later a Sportster. I do work for a wide variety of bikes and spent quite a bit of time at the drags, although not recently.
Curious thing about racing folks on the street, ya never know what they really got, and if you ask, they may not really tell you.
But keep this in mind, we are running 70,s bikes, and newer bikes are not the same as they were back then..
I usually dont have too much grief from riders of other makes,but I think that has more to do with the way you act and speak, than what you ride.You dont have to spend much time with any brand of riders to see a few people with distorted attitudes..
