Yes the ignition curve and rev limiter on the yz cdi are different from the wr.To get around this problem have a look at the VORTEX dual curve cdi, the wr one has the lighting circuit and in race mode is a little better than the stock yz cdi and in traction mode (via a handlebar mounted switch) becomes a bit more tractable than the stock wr cdi. The best of both worlds!!Search the archives for "vortex" or check it out at www.vortex-performance.com.au

Hope this helps
