[QUOTE="bclapham, post: 486688, member: 25565"] it sounds like the 68.5mm piston is a good way of getting more life and power from an old yz250 cylinder and still keeping the power characteristics of a great MX engine without making it into a woods bike. i think what we are seeing is that we rapidly approach the limits to how big we can take 2-strokes before the costs goes up exponentially! i suppose $1000 spent on a stroker would be better spent as a deposit on a CRF! its hard to justify that sort of money when you can buy a wiseco crank and rod ready to go for less than $200 thanks again for your input eric.
