Carried out the work last Sunday. Had the shims for a while but laziness had taken a hold on me.
All four rocker arms had clearances on the tight side. I expected the clearances to be loose, not tight?
Interestingly, all four arms had 2 x 0.3mm shims fitted. I expect that this is the standard BMW fitment upon leaving the factory? On both inlets I only had to remove one of the shims. On the exhausts, I removed both shims & replaced them with a 0.2mm shim in each arm.
The result is a quieter running engine, Worth doing, took about 2 hours in total, taking it easy. Easy to carry out as long as you have Verniers & a Micrometer. The shims are only 60p each from Sherlocks.
This bike is now for sale, see my posting in the relevant section, full spec on contacting me.
