Disconcerting whining noise from engine

[Guest]

did tightening the nut get rid of the rattle?

Inconclusive. It seems to have helped, but there are two factors that are keeping me from saying it fixed it.

1) I wasn't able to tighten the nut to the specified torque because I don't have the proper tool to hold the clutch still as I tighten it. It's certainly not finger loose any more like it had been though.
2) all six springs were below spec so I ordered a set of new OEM springs for it, but they haven't arrived yet.

After I get everything buttoned up the way it's supposed to be, I'll add another post to let everyone know the results.

Do you have a sound byte of the clutch rattle. The sound coming from my clutch is like a hollow pingy/clinky sound. Kind of like lightly tapping an aluminum wrench against one of the covers. I had someone PM me it's piston slap, but the sound does not come from the buckets, it comes from the lower back right end...stethoscope. I have no compression loss, no power loss, no performance issues and it only starts from 4k rpm while rolling, won't do it sitting still, had to lift the bike and roll the back wheel to narrow down sound area. I am thinking springs and nut for me too... from what I understand, it's more of an annoyance than anything. Just wanting to see if our sounds are similar. Can't tell from your videos.

I had my stator screws come just a little loose and it made a whining sound, just a thought, I later used Loctite on them after that.

Badly synched carbs can cause a rattle in the primary gears.

I'm pretty sure I have my carbs pretty well bench synched, but I have not done a vacuum sync yet because they need to be gone back through to do a thorough cleaning/jetting/etc. With that in mind, do you still think they could be the cause of my rattling?

Scott. Put the bike in fourth or fifth gear and jam a hammer handle into the rear brake pedal to hold the brakes on. This will hold the clutch shaft so you can torque it. Use a socket and a length of cheater pipes and get it good and tight. Bend the locking ring tab down and good enough.

You could also use a 2x2 or axe handle through the rear wheel to keep it from turning. I agree with the upper gears.

I would have never thought of either of those methods to keeping the engine from turning. Thanks guys! To paraphrase: "We don't need to stinking clutch basket holding tool!".

Well, the official tool IS the proper way, as it does not put any strain on any other part of the bike, but there ARE work-arounds.
