Welcome to the great world of the RIII.
First, there are no tappets, there are shims under the cams that may need adjustment. Second, get yourself TuneECU. It will allow you to retune your bike (best done with a dyno and somebody who knows what they are doing - although there are a lot of good tunings available which will be pretty close for excellent peerformance), and also trouble shoot and repair and adjust a whole bunch of other stuff. It is the most essential tool for the RIII, IMHO.
