'98 zx9r missing gears

[mattgt1000]

Anyone ever run into this problem, every gear just starting going in and out very inconsitantly, started with 3rd gear but now its pretty much all of them. What do u think it is? Anyone experience the same problem. The bike have 25,000 miles, and help appriciated

shifting forks could be bent, not keeping the gears in place or fully engaging them, or you clutch is not fully disengaging, that is the first two things I would check

few thoughts spring to mind:
1. Excessive play in gear change linkage.
2. Chain overly loose / tight / unlubricated
3. Clutch not disengaging properly as metioned above.
hydraulic on ealry models so try new fluid and bleeding.
Cable on later models try oiling and adjusting it.
4. Clutch plates worn into clutch basket preventing them opening, not happened on my 36,000 mile e2 but if your has been ridden hard its possible.
5. Internal Gear selection mechanism (Behind your front sprocket inside the engine covers)
6. After that it's looking at selector forks and drum in the gearbox (thats been an engine out job on every other bike I've had, but never looked at doing it on the 9).

That the order I'd look in, it's based as much on the easy things to check as the most likely things.
