Hello gang,

Started having issues this morning. Rode to work this morning got of the highway and trans missed a down shift. Did a couple down shifts went into gear and no issues. At the end of the day leaving work upshifting to get on highway missed again rode home about 20 miles and bike upshifts and downshifts fine. I ran it up and down through the gears several times in the drive way most of the time no issues but occasionally it misses. In the drive way you can hear like it does fully engage and can hear a slight grinding noise. Any suggestions or info is greatly appreciated.

Thanks,

Ray

Does the bike creep when the clutch is pulled in? Stand up and straddle your bike with the clutch pulled in,(to take your body weight off of it) in gear, and rev it up a lil...does the bike pull forward?[/url]

Mine will do this (pull when reved with clutch in, not shifting problem), I just assumed I needed to adjust the clutch cable a little.

Is this transmission in a Big dog? What year? I see you have an 05 listed under your name...if it's the 05, there are a number of problems with the 05 transmissions. I would look under bike to inspect for any oil leaks. You might have a counter shaft bolt that has loosened up and causing the C/S to walk. Bearings are a common problem as well depending on miles. Another thing to keep in mind is the problem with the main shafts. Do a search, you will find all my posts about the shaft along with other problems.
How long has this problem been going on? If it's not in the transmission itself, it could be a clutch issue, in which case the clutch hub nut may have stated to loosen up. Baker now sells a hardened nut you can replace the non hardened one with. They are $9.

Could it be bent/worn forks? Just throwing that in as I've seen it referenced in some other threads for tranny issues.

It could be. But normally a bent fork is caused from something else failing. And a worn fork will occur over time. The most common cause of a worn fork is from the rider resting his/her foot on the shift lever. They can also start to wear if the gears become offset due to bearing wear, counter shaft bolt backing out, or the clutch nut is loose.
I would say 99% of the transmissions I have seen and rebuilt with a problem like this is not a shift fork related. But, you can never say it's NOT the problem without taking it apart first.

Sorry guys got tied up with work yesterday. Yes this trans is in a BDM Chopper. The problem started the morning of my post never had happened before. Mileage wise I'm right at around 8000 miles as far as oil leaks a few drops on occassion but nothing excessive. As far as the clutch goes it doesn't creep forward but will kind of engage hard into first once in awhile and sometimes it will take a couple tries to find neutral. I took it.easy way home as to minimize any further damage. I do ride it hard when all is well though, I mean otherwise what's the point.

I would start with taking primary cover off first to inspect the clutch assembly. Make sure clutch nut is not loose.
But, with you having an oil leak and over 8k miles, it's safe to say most likely the transmission bearings are worn. I would be concerned about the older main shaft failing and the possibility of the counter shaft bolt backing out as well.
You can inspect for any play on the main shaft by pulling the clutch assembly out, along with inspecting the main shaft to see if it's the old or new. Have you owned this bike from day one? Ever had transmission work done to it before?

I don't want to step on Andrew and Doug's toes, they know what their talking about, but I have to put my two cents in, because I started having the same problem last summer. I found that my primary chain was very loose. After adjusting that the problem went away, and now that I have an open primary, it shifts better than it ever has. Check that first, it's easy to do. If it ok, follow what Andrew and Dour say.

Keep in mind, this is something he says just started giving him problems. I would think a loose chain or anything worn in the clutch, there would have been a gradual change in the way the bike was acting. But anything is possible.

Andrew any idea what I'm looking at as as shipping from New Mexico?. I tore it.down some but don't see anything out of the ordinary. Given your knowledge of the trans and like you said a possible lock up at highway speed isn't worth a guess. Send it to an experienced professional and done.

Thanks,
Ray

FedEx ground will run you around $60 most likely with $1800 insurance.
If you plan to send this, I would suggest ASAP. I leave April 14th for Europe and will be gone for 6 weeks.
:cheers:

Sorry Andrew I've been dealing with some estate issues of my grandmothers and then my internet went down. So I looked closer and I found that the shifter pawl assembly has a good groove worn in it on the top fork. I'm not sure if this would cause my issue just thought I would ask. I also do not see any type of debris or signs of damage. I'm going to send the trans off to you simply for peace of mind but I will wait until you return from your trip as I havent had the time to remove it yet nor will I have for a couple of weeks.
