Hi Everyone,
I've got an mc28 with a dry clutch and am trying to diagnose a kunk noise when shifting gears, mostly noticable in lower gears like going from nuetral to first, or first to second but you can hear it in other gear changes as well.

At first I thought the clutch was just worn out, or possibly needed adjustment so I replaced it with a brand new genuine Honda clutch but that did not fix the problem.

The noise is from the trans kunking into gear like the clutch isn't engaging all the way, now I'm thinking maybe I have a bent shift fork or shaft or something. It almost sounds like your shifting without using the clutch at all.

Anyone else dealt with this before, or know what might be broken?

Thanks,
Eric

Bad clutch cable adjustment?

Dave,
No, I've tried to adjust the hard shift out but I'm really thinking maybe I have a bent shift fork or shaft.

I was hoping someone else was already familiar with the prob and could give me some insight.

The bike is klunking into gear like it's not getting enough clutch action.

Thanks,
Eric

The only thing I know of is wear in the clutch basket - I'm assuming you didn't change this when you changed the plates?

The basket is alloy, and it will wear over time until there are notches in it that prevent a smooth action. Have a look at the fingers where the plates pass the torque accross, and it may simply be that causing the notchiness.

You may be able to file any slight wear out, if not it'll need a new basket.

Keep us informed!

I had this very same problem on my 21. A little birdie told me that if I changed out the bushings in the torque arm, the problem would go away, so I did, and it did. No more klunk. Look for part #9 on page J13. It is referred to as "Link Assembly, Engine Stopper. It takes all the lash in the engine assembly when you shift and feeds it into the frame. Worked a treat. Good luck.

Dave & Jim,
Thanks a million for the advice.

Dave,
I'll check the basket for wear and let you know what I find.

Jim,
Is wear in the bushes in the engine stopper noticable or can you even tell from looking at the thing if it's worn out?

On the 21 it looks like this peice can be serviced/replaced as an assy. On my 28 it appears honda only sells the busings seperate from the arm, I guess you would only really need the bushes anyway though.

I'll tell you I probably never would have thought to consider this peice as the source of the noise, are these bushings difficult to access and replace?

Eric

Yes, frankly, it was a pain in the butt. You need to pull the swingarm pivot. But you can tell if it's worn. Just grab it give it a good shake. If the bushings are gone, you'll know.

Thanks for the info, I'm planning to work on the bike this weekend and I'll let you guys know what I find.

Eric
