I estimate mine at 90 on flat ground. My speedometer is just 85 aswell, but the needle goes to about where 90 should be. I wanna get a recalibrated, more accurate speedometer like someone on another part of the forums was talking about..like 40 bucks to get the stock one repainted and recalibrated. If I ever get money to make the engine support higher RPMs, I will remove the RPM limiter.
