I have a quick question, if i change the rear sproket will that stuff up the speedo?ha top speed will be fine. How often do you run 130 or 140? Unless your on a huge track like texas world speedway you won't even notice it. I'm assuming your on a 6. You might get a few more mph's on a little bigger bike. I had -1 +2, i never had a complaint about top speed.
One of our local stunters just bought a 01 Honda 929RR off one of the Racing 905 boys, and it's got a -2 +15.Thats pretty good... Speedo will be off a lil tho..
Im bout to go -1 + 10
