Hello all,
I own two high mileage 1985 K100 (RS and RT), amongst other bikes. I'm in the process of checking valve clearances. All valves on both bikes are tight and need adjustment. I'd like to remove all shims and then see if any of the shims can be swapped to a new location, before ordering extra shims? Or would I cause damage to the valves by rotating the camshaft with a wrench without shims in place? What about having shims re-machined by a professional machine shop? Better to buy new?
Thanks!
