[QUOTE="Studboy, post: 1249230, member: 26867"] Most of the 2006 YZ250s do ping slightly on premium pump gas stock. The culprit: Excessive squishband clearance. My bike measured out at 0.085". I think that most of the new YZ250s are in that range. The remedy: Bring the squishband into the 0.050" +- 0.005" range. I achieved this by milling the cylinder head down and removing some material from the dome to keep the stock compression ratio. The results: No more pinging and better response! [/QUOTE]
