Rattle When releasing clutch from standstill

[bob mooreParticipant]

Just went on first run on MK1 r3 after full redo,  all went well,  did 250 miles and got 52mpg runs great , noted a bit of a rattling noise when releasing clutch when taking of in first , clutch works well easy to find neutral , everthing in the primary side is new , no noise when clutch is engaged or released , just a rattle buzz noise when taking off as the clutch is being released , any ideas

I would look carefully at either the chainwheel rivets or the clutch end cover rivets.

Also check if the crankshaft sprocket is a tight fit.
My triple was doing exactly that and i found out that the rattling was from there.
The sprocket was a loose fit on the crankshaft.

I remember the sprocket wasn’t  exactly a tight fit on the crank , although I torqued it up tight , the noise started after about an hours riding when it got really warmed up , so i will take of the cover and see if it is still tight , did you replace the sprocket ?

[john neokosmidisParticipant]

No i didn’t. I used loctite 660 to secure the sprocket on splines.
I also discarded the sprocket nut washer (70-8785) and make a new washer on the lathe
with a thickness of about 5mm. I secured the nut with loctite high strength thread locker. Obviously if i need to remove those items i have to warm them first.
