Bent Shifting fork?

I'm looking at an 81 maxim for $650.00 owner says that bike has trouble finding second gear and that a Yamaha Mech told him it is most likely a bent shifting fork or forks in the tranny. I'm wondering if that can be addresseded by a me with help from a shop manual - I'm a diesel tech for 25 years, but no experience with bike trans. Also can it be addressed with engine in place - no removal of engine from chassis. And how much will parts be? Otherwise the bike is in great shape. Thanks! John

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

I have a 03 yamaha vstar 1100 classic and here latley when accelerating hard in second gear the bike seems like the transmission is skipping (not slipping)... any ideas as to what in the tranny is causing...


Sounds like a bent shift fork. While accelerating you can feel the power cutting in and out quickly. The problem will get worse if you keep pushing 2nd gear till it slips. You can learn where (at what RPM) it wants to jump out and start shifting before it jumps out. The long term fix is opening the transmission and fixing the bent shift fork.

Have a yamaha 660 raptor and when I shift into second gear it's like it's not engaging in. I pulled the motor apart and can't see any stripped gears at all.


The bike has a bent shift fork. Identify the fork that is supposed to move the slider gear to engage second gear then replace the fork. Note; the fork will look okay to the eye. You can't see the bend even when comparing the old fork to a new one. Check the gear dogs on the slider gear. Are any dogs broken? tombones49_258.gif

I have a yamaha xj 650 81 model and its stuck in first gear


Sounds like a badly bent shift fork. Parts will be hard to find. Finding a dealer willing to work on a 30 year old bike will be even harder. The cost to repair would be around $1250. That is more than the bike is worth. I don't advise you to attempt the repair yourself. Some special tools are needed and you would be doing major surgery on the transmission.

1986 yz125


basically that problem comes from "banging" gears. that bike is 23 years old.its likely the shifting forks are bent to the point of just getting it into 2nd. only fix is to replace them. if they havent been replaced since the bike was new, its outstanding its only starting now. beware, if not replaced soon, its possible you may end up losing your 2nd gear. hope this helps..

Stuck in first gear


Sounds like a bent shift fork.
You will need an impact driver and torque wrench plus the normal screwdriver, pliers, etc.. Alternate to the special tools is taking it to the dealer and say "Fix it". I normally tell people to take it to the shop just so they don't get into such an involved project.

The motor comes out of the bike then turned upside down for removal of the bottom case. The gears and shafts gotta come out so you can get to the bad fork. There's much more but the idea is that you are better off having the shop do the repair..

Please rate this solution. Thanks

Stuck in first gear


This is a classic symptom of a bent shift fork. Why the Manufacturers don't make them stronger is beyond me. Did the bike fall over or the shift lever get hit by the lawnmower? The repair involves splitting the gearbox then replacing the bent fork. This is best done at the dealers shop unless you know what you are doing.

Please rate this answer. Thanks!
