On my 916, adjusting the chain tension does indeed alter the ride height.

How much by depends on whereabouts the eccentric is set and where you move it to but if you want to keep the geometry the same then you need to alter the ride height accordingly.

Fortunately ride height adjustment is very simple, as is the eccentric adjustment and, because the eccentric is the entire rear hub/bearing assembly, chain alignment is not affected.

I tend to get round the whole chain tension/ride height conundrum by rarely adjusting the chain...
