Weird Noises!

Just as the season was ending last year, the bike starting making a terrible noise. I'm finally around to taking it apart, but I'd like any input from you guys.

hopefully, the problem will be obvious as i take it apart. i'm hoping someone's heard this before and knows what it is.


it's an 07 d675

I wonder if the starter gear keeps engaging. Does pulling in the clutch change the noise?

i think that it did change the noise slightly... i also noticed that the clutch lever slack disappeared all of a sudden...

I suspect that it is the clutch. Layman's guess here but I wonder if a spring broke or something. You can make a "mechanics stethoscope" by putting a screwdriver handle in your ear and putting the tip In various areas on the outside of the motor and it will conduct sound much more precisely.

Hopefully it is the clutch, at least that is a reasonable repair and easy to get to.

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.

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?

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.

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

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.
