hi , just a question here , I installed the 16t sprocket and calibrated the speedohealer for the gearing change plus the site recomended 5.8% factory speedo error. Then I went out and did a top speed run , and when I returned I hit the top speed recall button , and it read 180 mph. I don't even know if this was the top speed , because I shut it down quick , I chickened-out basically. Now I thought the bike wasn't supposed to reach this speed , with this gearing. ??. The bike is a 2005 , is bone stock , with the exception of the sprocket and a 180/55 rear tire. The road was flat and there was no tailwind that I was aware of. Could the 5.8% factory speedo error be the wrong value ?. thanks for any reply's.
