      I’m finally getting into tuning my kart, after 7 or 8 events of chasing down various mechanical issues.  It’s a 2000-ish TrackMagic with a Honda CR125R and 40mm rear axle.

      At the moment, I have a 15 tooth sprocket on the engine and a 28 tooth rear sprocket.  This setup seems okay for Adam’s Motorsports Park, but seems a little too short for CalSpeedway and certainly too short for Apex in Perris.

      I have a 26 tooth rear sprocket that came with the kart that I just found when cleaning up the garage.  Would that setup match CalSpeedway and Apex?  It looks like it’s only 0.1 difference in ratio.

      Any suggestions on a rear sprocket would be great.  I’d like to show up with the best sprocket installed vs. spend three or four sessions testing out sprockets I wasted my money on.

      Thanks!
      Chris
