got a question. many wrf folks, on the 250 and 400/426 sides, have retimed their bikes to the yzf spec. performance in certain areas is improved, and there doesn't seem to be much downside. but can a yzf-timed wrf engine *really* perform like a stock yzf? the reason i ask is because i'm not sure that the two different bikes share the same mapping for their CDI units. in other words, is the CDI's 3D contour map (timing+throttle opening+rpm) the same for the wrf and yfzf engines? do the yz250f and wr250f use the exact same black box? is the computer on a yzf timed wrf operating under some incorrect assumptions?
