I believe I have a bent 1st gear shift fork
SOURCE: Bent Shifting fork?
dear swedishpytho the bic engine will have to be removed and split to expose the trany. you can likely do this job yourself but is is a big job reguiring shiming the shift forks and gears .the problem is likely a worn shift fork. a repair manual is a must for this job. the cost of parts i am not sure but beside the shift fork a complete gasket set will be reguired,and since the engine will be striped down you might as well rering the engine hope this helps jim
SOURCE: yz 250 2008 possible 5th gear stripped, or shifting fork bent?
Do an oil change. If the gear were stripped there will be lots of metal particles in the oil. More than likely the fork is slightly bent such that the slider for fifth gear is just barely engaging. Put pressure on it by increased throttle and it pops out.

How do I put this? Yes, you have a bent shift fork. And, yes, they can get bent in a fall, a dump, a drop or whatever terminology is used. The fork engages into a collar on a gear that slides left and right, (slider gear). Large "pins" called "dogs" are cast into the side of the gear. The dogs engage into holes in the side of the gear you are shifting into. Question: What happens if the bike drops on the clutch side and the shift lever is forced down, moving the slider gear to engage first gear even though the holes in the side of first gear are not lined up with the dogs on the slider gear? "You get a bent shift fork" is the correct answer. The force of the shifter lever moving the shift fork into the solid parts of first gear, (not lining up with the holes), is easily great enough to bend a fork. That pressure has got to go somewhere.
The repair means removal of the engine and a complete tear down of the engine/gearbox. The replacement of the bad fork is a given. But I suggest you do some preventative maintenance now, while the engine is apart anyway. Replace the sprocket shaft left bearing and seal, both crankshaft bearings and seals, shift shaft seal and the water pump seals. These are pretty low cost items and replacing them will mean you have pretty much rebuilt the engine. Have the dealer check the shift shaft to be sure it does not now have a bend in it.

SOURCE: How much shuld I ask for???
Without bent forks the bike would sell for about $1500. With the shop charge of $900 to fix the forks and a buyers hesitation to purchase a bike with problems, it will probably sell for $500 as a fair price.
I don't get paid for my answers but I do take pride in them, and I am only trying to help. So if you will, > > A “very helpful” rating for this answer? Thanks!
