Tons of threads on here about 250es /sx shifting issues .
Just pull the left side engine cover and see what’s broken or possibly just loose .
Very common problem .

Actually the left side crankcases is NOT the only side that shifting problems can occur. If you didn't find it in the left side, the it's the right side crankcase where the issue is. I have the same model and year trike and just fixed issues with mine and all were right side crankcase cover.

Under the right side cover, you'll find that's where the reverse selector mechanism is...it's located on the very bottom underneath both clutch's. It has a spring on it that has 2 sides...one part of the spring locks onto the lever mechanism its on, and the other part of the spring (the part that holds tension..the straight section of the spring) is supposed to rest above the filter screen thing housing. My guess is either that spring broke or came loose.

The other part in there is the gear selector arm. The foot shift lever grabs onto the spline shaft...and that shaft goes all the way through the block and pokes out the other end of itself inside the right crankcase. The thing that slides onto it is the gear selector arm. On the end of that arm is supposed to be a free spinning little metal roller thing. On my 250sx..that little roller thing got pressed on hard enough to permanantly jam that roller thing and kept it from spinning. If it can't spin freely, then the gears will stick. You should also check the mechanism that little roller thing is supposed to move..the clutch adjuster plate with the "V" notch in it. My guess is your problem is probably the reverse selector arm and spring. Fairly easy fix. Hope this helps some if you haven't fixed already!
