Question 15 tooth or 16 tooth counter sprocket
Ninja 250. @70mph, tachs slightly over 8k rpm, if speedo is correct. Has anyone put a 15 tooth c-sprocket on and how does it perform? Has anyone put the 16 tooth c-sprocket on and how does it perform? I know hole shot will definitly will be much slower. But does it overload the engine? I went to a website, speed calculator, and according to the chart it will drop rpm's approximately 1k @ 70 mph. Any input?
