Question about 2002 Yamaha YZ 426 F

1 Answer

Yz 250 2008 possible 5th gear stripped, or shifting fork bent?

1 through 4 is ok.but in 5th bike revs, but nothing to rear wheel seems to slip. New rings, piston, power valve fitted. Bike shop seems to think the 5 th gear is stripped because this is an apparent problem with the YZ. Thanks 2002 YZ426F is good 1 thru 4, when I shift into 5th, it goes in and out of the gear, almost seems like it is running out of gas, or the gear is slipping, if I baby it, it works, as soon as I get on it in 5th only, it starts slipping, could this be the shifting fork?

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.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

I have a 2009 yz250 with a good amount of time on it and i believe 2nd gear is out of it. it grinds n almost sounds like a chain slipping when i get on the gas and is like its in neutrel. what does it take...

Yes, the case will need to be split. The problem is likely to be a bent shift fork. A bent fork can stop the dogs on the slider gear from fully engaging in a gear. If the problem turns out to be a stripped gear, you need to replace BOTH the stripped gear AND the gear the bad gear meshes with. tombones49_273.gif

I have a 1999 yz 400f and it seems to be stuck in 2nd gear

Hi, Williamsa585 and the usual suspects are:
1. Clutch not disengaging.
2. Bent shift shaft.
3. Shift fork bent or seized.
4. Gear seized on the shaft.
5. Gear positioning lever binding.
6. Shift return springs weak or broken.
7. Shift return spring pin loose
8. Shift mechanism arm spring is broken.
9. Shift mechanism arm is broken.
10. Shift drum is broken.

Ok my crf150f the shifter wont shift after i get into 3rd gear unless i just tap the shifter a little bit then i got to do it again to get into 5th gear i need help fast please a diagram would help lots

It could be a loose shift index wheel or a weak index wheel spring. The index cam could be loose also. Another item to check is the shifter shaft and return spring. There could be a slightly bent shift fork causing the problem, but since you didn't mention having to force the shift pedal I doubt that is the cause. By the way, if a shift fork is bent, an engine tear down will be needed.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site.

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..

?3rd? gear it slips win power is applied

You should be admired for being able to tear into the guts of this bike, find a problem and fix it. Most guys would back away, and rightfully so if lacking mechanical ability and tools. Strange that only 3rd gear is affected. The only possible thing I can think of is to stick in new fiber clutch plates. The plates have been used for 22 years and thousands of miles. Time to replace them just on the principle of the matter. Post a comment on how things turn out!

Yz 250 2008 possible 5th gear stripped?

I doubt that any gears are stripped. Believe me you would have known it when it happened at 40mph which is where you would have to be in 5th gear. This is a bent shift fork. The actual gear is fine. The slider gear is not moving far enough to engage with 5th gear. The YZ does tend to have this problem in 5th and 1st. "Dirt rider Magazine " did a story on it. Best to let the shop do the repair as the entire motor gets torn down into about 100 parts.

Iv got a 01 dosent click into 5th gear.All it does is make a clunky noise like its trying to click in but nothing happens.1n234 are algood.anyone know whats happening??

You have a bent shift fork. The engine will need to come out of the bike then the gear box gets opened up, ( major repair job ), the offending shift fork gets replaced then all gets reassembled. This is not a project for the amature mechanic unless you want to buy a new bike.

5th. Gear

Sounds like you may have bent a shift fork or your cluster gear has some missing teeth on it now. I would venture to say that is it a bent shift fork. This will require the transmission be removed to gain access to inspect and repair.
