F650GS Twin valve clearances

ShakeyBMW · Apr 23, 2018

I’m trying to find the right valve clearance figures for my wife’s F650GS Twin (2011) and have found the information here and on other forums.

I’m confused by references I’ve found to “new values” although these may actually apply to the engine in full F800 form. The numbers I have are;

Inlet
0.18 - 0.26mm. (New values 0.23 - 0.33mm)
Exhaust
0.27 - 0.35mm. (New values 0.30 - 0.41mm)

Any gurus here know which figures are the correct ones?

Not a guru, more of a Gnu.
According to Haines, your first figures are correct. I have never seen the reference to "new values" anywhere.
We await the arrival of a guru with an explanation of the new values with baited breath.

Thanks Bem. Much appreciated.

For a brief period BMW changed to the larger clearances but then changed back to the original specs.
