Im experiencing a power plateau on my last couple of test rides, what feels like before my kart was kicking and pulling hard now feels like its got less than its balls at the same throttle and speeds. besides a couple of rough test runs with really high gearing, nothing has changed, I was going to rip it apart this week anyway for lower gearing, but now I have concerns we should look at replacing other parts. So aside from some springs and weights, is there anything else in the clutch system I should look to for any issues? Its a 18hp duromax running stage 1 with governor. currently running 17/54 because thats what we had but I have a 10 and 12t here finally to try out. Were running a china 40 series with upgraded springs. before this thing has hit 50+ no issue now it struggles it feels like past 35mph..
