CV axle going bad??
So here is a strange one.
When making a slow speed, left turn, in first or second gear (maybe third but I don't know) with the clutch depressed, I get a clacking/clunking noise from the primary. Sounds a bit like the gear dogs clacking together (I think) and it only does it when the bike is leaning left and the clutch is depressed while in gear.
I also notice when I was backing my bike into a parking spot with the tranny in neutral, that it would make a clack-clack-clack with the rotation of the wheels. Hadn't noticed that before.
Anyone got ideas of what it could be? My wife said it might be the tie-rods but I'm thinking CV axle.

Need a video of this one I think.
The turning left part would make me suspect that it is clutch cable related, could the cable be pulling or binding on something causing it to over pull the clutch basket?

Kind of hard to make a rolling video.

That's one I'll check this evening. I recently had the primary cover off and replaced the tensioner pad. I believe I correctly set the primary chain tension, but that's not to say it didn't loosen up for some strange reason.
I stopped by my local indy today and had a chat with the mech/tech. That was one of the things he brought up as well along with a clutch bearing or maybe the spring plate.
I'll start with chain tension and clutch adjustment as the easiest things to check/correct.
Thanks for your input and help.

It could very well be the spring plate. That's the place that for some reason HD puts in the middle of the clutch plate pack. It is made of two steel plates with some spring metal pieces inbetween and is all held together with some brass rivets. Those brass rivets are a soft metal that are know to shear off allowing some of the spring metal pieces to swing out as the clutch is spinning. If that is the case, eventually they will all shear and the small spring metal pieces could be spread all through the clutch and gear area. Of course the only way to see if it is the problem is to remove half the clutch plates to access the spring plate and see. But if you take off the left side cover and see little brass pieces, that is the problem and should be replace. Don't get another spring plate but replace the entire clutch pack with a set that includes the extra plate that replaces the spring plate. Like the ones here:

But it seems that if the spring plate were coming apart, the noise would be more constant.
Either way, I'll be replacing it soon.

Do you have spoked wheels by chance? The reason I ask is I had a very similar experience when I got my bike back from the shop a couple weeks ago. While moving the bike I was hearing a loud clacking as you described.
I thought something was going on inside the primary but found that the spokes on the rear wheel had loosened up a bit and were making the noise due to them slightly shifting and rubbing on each other. I tightened them up and the noise is gone. If you have spokes maybe check the tension.

I appreciate the input. I never dreamed that I should have said I have cast wheels.
