Finally got around to putting a 16 tooth Renthal sprocket on the front and let me tell you this thing seems crazy in the front end. 1st and 2nd forget about ham fisting the throttle, 3rd, 4th...if you hit any find of irregularity in the road with even a mild twist of the wrist the front wheel wants to paw at the sky. I'm riding with an entire new respect for the right hand. I'm going to try +2 at the back as well at a later date. Install was not too bad, used an electric impact. The rear wheel had to be adjusted back a bit more than I anticipated, not much but more than I would have guessed but I think the chaIin was a bit loose initially on the 17 tooth. Oh well, I highly recommend this inexpensive mod.
