Where the gen 4 zx10s get their speedo reading from?
I had mine in the shop for a service this week and was going to go 1 tooth smaller in the front, but the service manager actually rang me and said that doing so would throw the speedo out. I told him that wasn't the case because it takes the reading from the front wheel.
He then rung me back an hour later and told me that he rung kawasaki and they told him it was taken from the front sprocket imput shaft.
So in the end, rather than telling him that he was full of shit, which i still think he is lol, just to leave it then.
Who was right??
