I dropped 1 tooth on the front and raised 2 on the back.
It upped the revs at 70mph by about 500. I still get about 170 miles to a tank. Acceleration is better obviously.
It does send the speedo out of wack, you could make a mark on the speedo where the proper limits are but I got a speedo healer and adjusted that until my speedo matched my phone gps.
I got a gold x ring chain with renthal sprockets 'racing gearing' kit off ebay from a bike shop.
I asked them about changing both sprockets and they said 1 tooth off the front was like putting 3 on the back so putting 2 on the rear wasn't a big step.
I will see if I can find a link for the kit I got.
It was arracing-uk but they don't have a racing kit listed at the minute.
