[QUOTE="Rich Rohrich, post: 107322, member: 16241"] That's seems like the normal production clearance on WRs. The head gasket compresses to about .035" + - .001" . I've seen WR's average .060"-.080" total squish with YZs coming in about .010" less . The WRs used to come with a base gasket that was about .010" thicker, but I haven't checked the part numbers on the new ones. It certainly hasn't been widespread if there is. Will has put some seriously high race miles on his YZFs with good results save for one crank issue. The stuff I've seen and the e-mails I get points to the crank/rod being pretty stout as long as good quality clean oil runs through the engine. As soon as I get the cams I'll make a new more accurate fixture and I'll post the Cam Doctor numbers. It should prove ionteresting. [/QUOTE]
