Bump. What a great write up! I will definitely be using this as a guide. I have to replace the crankcase from a low side crash. Yes, I found a spare one, lets only hope they mate up together with no problems. Otherwise...

Cheapest place I found to get parts was Cheapcycleparts.com they were about 10% lower than anyone else.

To Jupiter, $340 to fix 2nd gear is money WELL spent. All the people (dealers) who work on bikes around here just mess it up more than fix anything, so I figured I dont have to pay anyone to screw up my bike, I can do that myself for alot less! But this was a fun project.

Nice write up, Good for if a gear is worn and needs to be replaced... You're right about the 929s having second gear miss shifts, but those without trashed transmissions can save yourself a lot of time, money, and effort by putting in a Shift Kit with new arm, spring, and star... Completely solves the problem :thumb:

Great write-up, perfect for preparation for my own small digging ...

Thought about it a lot, and basically decided (after looking at your pictures) that the main culprit should be the shift-forks, not the dogs or the gears.

My theory:
The wear on dogs and gears is caused by the incorrect position of the forks, this caused by wear, inproper operation and/or the shift drum stopper.
I doubt this kind of wear on dogs and gars alone will cause the 2nd gear getting into neutral.
But a bent or worn gear fork will.
I agree that replacing all parts mentioned is the right way to go on a 'keeper' bike, but I think replacing the fork(s) might do the trick.
Am I right in this, pls. shoot....

Last question: which fork is for the 2nd gear, the L, centre or R?

Hi guys, i am new to this forum, and i also have been working on a 2001 cbr 929 erion that has a second gear problem. I just got this bike from a guy in cda idaho and when i picked the bike up 3 weeks ago the battery was dear so i could not test ride the bike and with me being excited due to this bike being so bad azz lol i took the bike anyway. got her home and realized the stator cover was cracked pretty much in half howebver he did tell me about that. anyway the bike pops out of seconf d gear into neautral so i drained the oil and took the clutch out and pulled the shift drum and the forks. the drum has a wear spot where the forks nub looks to have been hitting hard and wore down the corner. and ll 3 shift forks have wear on them. now i have been reading on the forum for about a week straight and came up with replacing the shift drum and forks to solve this problem, anyone have any other possibilities? as far as i can tell the gears have no worn edges. Was hoping to fix the bike without splitting the case in half. lol

I just finished rebuilding my son's 954 trans earlier this month. To the guys that think a drum/fork replacement is the answer to your trnsmission woes I'll reply, "wishful thinking". Nobody wants to go into these trans and I'll even admit it's a bunch of work. However, you will absolutely know what you have when you're done.

My son's trans just randomly started dropping out of 4th gear. I didn't even believe him at first. I rode it three times before it did it to me. I immediately told him to stop riding it. Remember, your engine and trans are one. If your trans is going south, the trans debris is in your engine!

After removing the engine and removing the trans I was in shock! It only had a 4th gear problem? Ha! There was far more damage than I had suspected. The dogs on most all the gears were beat. Shift drum nicked up, one shift fork shot. I was surprised how well the trans had been working considering the damage.

Due to the numerous parts needed to properly repair the trans, I took a chance on Ebay for a complete trans. I was able to get a used one fairly cheap. Unfortunately, it had issues too but it gave me enough parts to make a good trans between it and my son's. I did have to buy one new gear from Honda. Also, as another member mentioned, the 954 has torque to yield bolts on the mains that must be replaced. They are single use and cannot be reused. Not sure if the 929 uses them or not.

The bike is now performing flawlessly! Rock solid! After having to remove so much to do this job, everything got serviced, inspected and replaced/repaired as necessary. I know my son will now have a trouble free bike to ride. This is a GOOD thing! Ha!

Like I said, don't fool yourself. If your trans is giving you issues, a bandaid isn't going to fix it!

There is no need to replace everything. Just replace the worn or damaged parts.
Ron Ayres have pretty good pricing but there are plenty of others.

Exactly. Like I said, I was able to salvage the good from my son's trans, the good from the Ebay trans I bought and one new gear from Honda. Open it up, inspect, salvage the good, replace the bad.

Yes, you have to remove the swing arm,just follow the instruction and the picture that was posted. Just make sure you take your time that way you don't make a mistake. Got done with mine, 4th gear is my problem, replace the gears, drum and forks.
