im looking at a 460 stroker engine for my 400EX on ebay .. i emailed the guy asking about longeity he says it'll be fine will last a long long time blah blah but anyone will say what you WANT to hear to make a buck..
here's the listing
Would this engine last ?
I mainly do trail riding and dunes once every other month or so..
Ps im looking at it because my current engine is locked up and the crank bearings a shit..
