That explains it, I don't follow current Pro stock racing, it is too much of a deep pockets contest now. I was referring more to the everyday race bikes at the track ridden by the weekend warrior types. Here is where the 16v GS1100/1150 have reigned for 20 years. V+H racing made their reputation in the '80's on 16v GS Suzuki's.
Its all a moot point now as the average guy can buy a stock Busa and with a little launch savy be in the 9's without much effort.
Very interesting, I'd like to see how much a 1500cc motor has in common with a GS1000 powerplant. I imagine not much- billet everything probably- again a deep pockets contest.
Ride On, Ed.
