Hello David
Until this year there were several shifters at Batavia. Biggest problem was other than a few of us on Sunday most chose to run theres on Saturday for practice rather than come and race on Sunday. For some it was an inability to be at the track on Sunday, some others stated more track time during a practice day.
Now I have been racing my shifter since 2001. On race day you get over an hour of practice 20-30 laps easily! Then 2 - 10 lap heats and a 20 lap main. If you are driving a shifter at the max level of it's ability, you should have enough track time on Sunday!
I would love to see the shifters pick back up at Batavia. I currently have a full 125 moto setup but would opt for a stock Honda motor package if there are any other interested parties. Besides the stock Honda is a growing national class and can be run at most other close tracks i.e. OVRP, St Lawrence, Beaverun
By the way, the bump on the straight is your least concern. There is a peddle on the front of the kart on the right side called the throttle, Just let off for a millisecond!

Hope to see you out there. feel free to contact with any other questions
