A better, 54 millimeter bore cylinder for the Stihl 066 was 8 months in the making. We have Cross Performance Cylinders and Mastermind Worksaws to thank for this beast.
Cross Performance got Randy Evans, a.k.a. Mastermind, to analyze a new oem top end kit for a Stihl 066. Certain that he could improve it, ol' Peg Legs put it on the lathe and stuff.
With some port timing tweaks, better port shapes, and now boasting a bump in compression with better squish band design to increase squish velocity, the cylinder was sent back to Cross Performance.
The beefed up MMWS Stihl 066 cylinder prototype went to Cross Performance for manufacturing and a mold was made out of it.
Unfortunately, when a newly manufactured replacement Stihl 066 cylinder prototype was shipped back to Mastermind Worksaws, it was deemed that the exhaust port shape was not up to Randy's standards. Randy did some changes and sent it back to Cross for remanufacturing in due time.
The next rendition was really good.....and the rest is history.
...And here it is...
