from the looks of it its quite a bit of machining and work, but i really bet it pays off in the end. http://www.3wheelerworldforums.com/s...ad.php?t=78141
the ascott head is built to work with a 89mm bore...add a 6mm stroker to this and you got a 460cc motor that will out run most
with the 89mm bore (xr500 piston and sleeve) you get to run off the shelf parts and gaskets, not hard to find custom stuff
just read my thread hondahaulic posted and see what it takes
80s......185 atc, Yamaha tri-moto 200, 85 200x with tons of work
90s......89 Suzuki quad racer 250 (raced 250 A class for 6 years, late 90s.. custom framed 250x with long travel shocks and a built 350x motor.... built Honda 110
