Another engine rattle really bad noise

[Chri5]

Well my clutch bolts arrived so ive finally finished that. I just want to say thanks to everyone. Especially the frame information! Under inspection of the shim spaces some previous owner had put washers in the wrong places. There was no shim on the bell housing bolt 3 on the plug tank frame and there should of been. there was a 1.85mm gap. when installed properly the frame just slipped on. i ran out of light before i put the electrics back together so its not totally finished but the leg work is done. I should be back on the tarmac tomorrow

It might be, or it could be that the piston on the switch is stuck. Fast idle speed adjustment is explained in the downloadable BMW K75/K100 2V manual here on page 13–06.0. Attached is a photo of the switch.

I have found that the adjustment of those switches can be, uh, rather finicky.  And difficult to reach.   In my case, it wouldn't turn on the instrument cluster light.

Ill have a look tonight. it looks like the rear brake light switch which has given  so much trouble over  last 3 years constant cleaning and an annual replacement 😢

What is this fast idle light of which you speak?

[Filmcamera]

It is a yellow choke light on the dash, my bike does not have the switch but there is room for it on the loom - the choke connection.  Max BMW sell the wiring to add it to the harness, I believe it is part no.

That choke/fast idle light wasn't even supplied in my moto's year of manufacture. Like TMG indicates, you could disconnect it. If a rider can't keep track of when the fast idle is activated and when it isn't without a light indicating its status, motorcycle riding is likely too complicated to pursue. In temperatures down to 20ºF, I shut off the fast idle if it is needed for starting by the time I'm in third gear.
