I searched and searched. i couldn't find anything. Perhaps I missed it in a thread somewhere. Does anyone know what the stock speedometer error is on our bikes. I have an 08. I was going to run a 16T front but prefer the oem 17 sprocket! I know their site says "most bikes are off around 5%." Has anyone tested the oem correction value using radar or anything? Please let me know if anyone has. thanks in advance!
