Looks like the 14t raised the RPM on average about 500. I will know more tomorrow when I ride to work.
RPM will now be 7.143% higher than before (from 4000 to 4285.72, 5000 to 5357.15, 6000 to 6428.56) at the same actual speed in the same gear, but it won't change the tachometer to indicated speed relation. Speedometer error is now increased from about 7% to 14% over actual speed. Odometer/tripmeters which were near accurate before, now count about 7% over actual distance covered.
Had my GPS this morning. 80 mph indicated is 70 mph on the GPS and I am running just under 5900 RPM. I am really liking this 14 t front sprocket. Gives the bike the get up and go I expected it to have in the first place.
After more riding I have noticed its pretty easy in 6th gear to use the tach as your speedo. 4000 RPM is 50 mph dead nuts as is 3000 RPM is 40 mph and 6000 RPM is 70 MPH.
