Clunk when overrun/acceleration

[Adamastor]

Back to the internet after taking the R65 to work... the clunk is mostly gone, I believe I had the pivot pins too loose. They are atm hand tight right now, should I torque them harder? Unfortunately my torque tool doesnt have the key needed for the pivot pin
Last night, and thinking my driveshaft was ruined I searched ebay for parts, and found a R65 driveshaft in good shape auction almost at the end for very cheap. I won that auction for 21£ so even if this was not the problem, I will have a spare if I need it in the future.

I want to keep my R65 for many years

She looked really nice when I bought it, but she has made me spend quite a lot lately, but hopefully will be all ok soon
And your help has been priceless!

Oh, I messed a bit with the throttle cable ajusters (balancing carbs) and it vibrates less bellow 3000rpm (but still vibrates a bit, that's normal, right?).

Just to confuse things I'll toss this out of left field. Is the engine mount bolt tight? Did someone rubber mount the engine or are there solid spacers between the frame and crankcase.
Returning to left field,

Rich, I will check that out.. I didnt mess with those engine mount bolts, but they could be out of spec... Thanks for the tip...

You're talking about the swing arm pins?  That's a two stage torquing process, but I don't remember the numbers.  I would have to go look them up on Snowbum's web site, where he has a good description of the procedure.

I got a set of metric allen head drivers that attach to a 3/8 ratchet (or torque wrench) at Harbor Freight and they work fine.

Yes Ed, I saw that on Snowbum's site today... I will try to buy tomorrow an adapter at the hardware store. I am missing the first stage torquing...

It really felt good to come to work on the R65 today.. came by the countryside roads because of the new rings brake in process...

7.5 lb/ft for the bearing pins and 72 lb/ft for the lock nut are the final settings. The first stage for the pin is higher than 7.5 to seat the bearings but I can't remember what the figure is. It's probably not that critical say 15 lb/ft.

You really should use the special tool (short box spanner) so you can hold the bearing pin while tightening the lock nut.  I managed ok by putting a dab of paint on the pin so I could check the pin didn't move.

The bearings sit on the swing arm pins, the lock nut, pushes on the large area washer and preloads the swing arm bearings .
