Well, I had my tach calibrated today and it read 40 rpm low. So when the tach was at 7500 rpm the actual eng. rpm's were 7460. I have a "01" ZR800. FYI.

To bad the speedo's arn't as close ( percentage) wise. Tues the 8th was at my plowed speed track  
WITH gps unit and the sled my zl800 went just over 113, however the speedo was wrapped around on the bottom some where
 Any way, when i held it at 100 on the speedo, GPS unt said 89.7!!!!!!!
