i am going to Roebling Road in March with my stock Honda sprint kart. I was wondering what changes I need to make to the kart for road racing. Like wheel size, tire compounds, gearing, chain oiler, etc.
Also what class should I run. I am 55 and have no idea. Also would like to pit with someone of the same class so I can have someone to ask for advice if possible.
The class would be Stock Honda. (390 lbs). You could also participate in cik125(modified 125/kz 385 lbs)
Most common tire is MG yellow although some have had issues there w / excessive wear or blistering. Some have used MG orange. Chassis setup obviously makes a difference. Wheels are the same as sprint.
I’ve never run Roebling Road but I’d expect gear ratios to be around 1.20. 19/23 15/18 16/19. Not sure chain oilers are allowed, but a good chain lube like silkolene applied every outing should be fine.
Some things to watch for sprint to RR is brake and steering components must be safety wired, a secondary cable or back up between brake pedal and master cylinders. Full width rear bumper, newer plastic ones meet requirements may be a bit much on drag compared to steel tube rear bumpers.
