Bmore checked the stator again, looked very closely at things, tugged at things, nothing's giving... just for shits, i checked the torque on the stator bolts and CPS and its wire tie-down... CPS was tight, wire bracket tightened slightly, but each of the three stator bolts got about a quarter turn or less - not much but something... put it all back together and started it and voila, no more noise.

i can't remember if i thread-locked those bolts last time i was in there... but thousands of miles later, they got loose enough to allow some kind of stator movement. i'm very glad and lucky to catch it before anything worse happened. i need this used stator to last a while before the next used stator....

Bmore unfortunately, i've had this cover off many times to replace a bad stator with other used but not as bad stators.... i'll look again tonight, i think you're on to something

Razgreeze Prior to this noise have you ever had the stator cover off? Im sure you checked but I wonder if any of the Allen bolts that retain the crank position sensor backed out or if there is anything that may momentarily interfere with the spinning stator. I know one time when I put my crank position sensor back in the wire was rubbing on the stator but that I knew about immediately and turnedthe bike off and knew it was my fault.

Bmore changed some valve shims, deleted the SAS, new plugs and new gaskets, new fancy Motul oil...

the bike starts and runs, but the sound persists, albeit not as loudly and not as mysteriously. in fact, the sound is clearly coming from behind the stator cover, and it doesn't happen immediately after starts.... i checked the stator already and nothing seemed amiss. bolts were tight, wires were still clamped down, the rotor wasn't loose, the one-way starter gear was still going one way.... i don't know if i mentioned in an earlier post, but there was absolutely no metal bits or filings from the oil or from any cavity when fishing a magnet everywhere....

something has to be loose and rubbing something. guess i'll take the cover off again and look closely-er.

keeena The wear looks as expected and would have nothing to do with the noise.

It is possible to smooth out those notches in the basket and hub but it doesn't look bad enough to warrant cleaning them up.

so 37k+ miles total... i assume this wear on the basket is normal.... right? maybe the grooves are a little too deep? would it be causing the noise?

clutch plates look very good, no bluing or warping.

i also took off the valve cover to eventually check clearances. nothing unusual up top so far

Yep, I used OEM when I did mine this past spring. Never had a problem w/ OEM clutch bits (generally).

TTRIgnitionSystems On the old FZRs, a suddenly noisy & heavy clutch was an indicator that the push rod had snapped. This was generally caused by insufficient free play in the cable, resulting in the throwout bearing welding itself to the push rod.


I realise these machines use a rather different mechanism, but the failure mode would be the same. The cure is also the same - tear the clutch down, and inspect the throwout mechanism.

Bmore was wondering,

there are no good aftermarket clutch kits for these bikes, right?

EBC sells just the friction plates.... so is everyone buying original Triumph clutch parts for clutch jobs?

keeena Hard to tell from the audio. But if your clutch lever is behaving differently: worth having a look.

I mostly came by to tell you that the clutch cover is obnoxious to re-install on these bikes. Pay close attention to the angle you have to tilt it to clear the frame. There's probably some posts on this site with more tips.
