Where are you located? I’m from MN and my brother and I have been running shifter for a long time but your correct. Shifters aren’t healthy as far as sprint racing. The CES series has a large group of shifters that run at Blackhawk IL, Grattan, Gingerman and there is the KART enduro series as well. As for Sprint racing there isn’t much going on. Stock moto hasn’t taken hold in the Midwest as much. For the most part the clubs don’t have shifters anymore so there is no feeder to people running them.
