clutch chatter at idle APE clutch hub nut

[garyS-NJ]

Is the APE nut necessary for street riding??

My '79 gs1000 chutch chatters at low idle and I'm expecting its a loose hub nut (hoping that's all it is.). The bike has 42K miles and I got it running pretty good and roadworthy but I haven't put many miles on it.

Gonna get a good look at the clutch but if the nut is loose, should I order the APE nut and wait or cranks that sucker on and get back on the road? I have other bikes but just got the front end on the gs and want to ride it. Oh, and what about cranking the nut on? years back I broke a harley trans main shaft I forget what I was doing but it involved the clutch hub nut. On the GS is it regular right hand threads and is there a procedure for locking the shaft and torquing the nut or do I just hit it with electric impact??

The GS1150 nut is a good alternative if cost is important. It's beefier than the stock nut and a good bit cheaper than the APE nut.
Best method to hold the hub is using a tool like the service manual shows. EBC sells such a tool for about $20.

Oh, and the rattle may be from the hub itself. An extremely common issue on the GS1000. I shimmed the springs on one clutch hub and it quieted down the noise quite a bit. I had another GS1000 with a HD backplate w/HD springs and not only was the bike quiet, the clutch action was much improved. Problem is it's hard to find the HD rebuild kits these days.

awesome, thanks. I could do that backing plate spring shim and I think tack the rivets with my harbor freight wire feed welder (I can't imagine that the rivets need so much a weld as shown in the flying banana rework.) ,,, oh and the HD back plate and ??HD springs, if I were to go that route, who was the manufacturer? or part numbers?? where should I look for that HD set up

So hold the hub and torque, I'll need to check the manual. with harleys, I used to jam something in there to hold the hub and torque but then I got an electric impact and that delivered just the "right amount of touque". and the nut is regular right hand threads>??
