cr250/400ex swap??

[brewster426]

my 426ex needs a rebuild and i want to go through the whole top end/valvetrain. But i was looking on ebay and i saw a few cr250 motors for pretty cheep. i was wondering what the horsepower difference is..i know the 250 motor is a TON lighter especially with no electric start or battery. I have looked at the hybrid section and i see that the swap isnt really all that hard, i am a sheetmetal fabricator so the mounts and exhaust fab shouldnt be an issue. i was just wanting some opinions on whether its worth it or not, and some pro/cons. Thanks guys, Brewer

we have one right now...its quick and stuff...but idk id rather have a 400ex...id only really want to go with a 450 dirtbike or cr 500 or xr 650r for a hybrid....something faster and somewhat unique for all of the headache
