CRF250L 300cc Crank


Want to change my crank on my 2017 crf250l

To a 300cc crank and cams…which they say will be 286cc… I have read the files but that’s for president 2017 model.. Has anyone done this mod on a 2017….not sure which parts I actually need… Any ideas

    Complete tear down. Top end removal splitting cases and taking it down. Find a blown up 250l engine…if you have to ask this question your prob not competent enough to do the work no offsense


    If I do crank and cams it will be 286cc.. No need change piston as the stroke is different… Cams and ECU.. Gaskets etc
