2014 CRF 250 bent shift shaft.

you don't have to split the cases however you have to drain the coolant and the clutch/tranny oil, remove the inner/big clutch cover, remove the clutch and it will come out from behind the clutch basket.

Depending on how bad it is bent you might have to cut it from the clutch side and push it out of the motor that way if its not bent to bad you can remove the shift lever and pull it out that way however it might not want to come out with it being bent. I just had to cut one and take it out the shift lever side it was bent so bad.

I did the same thing to my 2010 CFR 250 not too long ago. I honed the center out where the shifter teeth are with a dremel and then pushed it thru. Watch out for knocking the case where the oil seal seats, I had to put some RTV at the seal cause I hit the case a couple times, better than cutting on the clutch side as that might get unwanted debris in your engine.
