whats the biggest 250X out there? i know you can get bored(87mm) and stroked (+12.7[70mm])to a 416cc, but i heard you can stroke it even more to somethin bigger? let me know what you guys got....

or 300EX(416) or 350X(430cc)

acually i think maybe even a 419 with +13.2mm stroke that i saw on an old post(dont know if true)....crazy huh...a guy i kno has a 406 he says you need a strong leg for lol
but yeah the +12.7 gives you the same stroke as a 400EX and its acually a 400EX sleeve bored .040 for the 406 -400EX piston wont work, you need to search to find the right one
as for price just the stroker kit alone is over $300 from www.powroll.com(they only carry a 352cc-over $1200) and you'd have to split the bottom end with all the trans.

oh and for a 400EX sleeve you need case machining

THANK YOU FOR ACUALLY REPLYING!!!!!!!LOL
