They like around 45mm but that's max slack with a new chain and that's pulling/pushing on the chain and forget using the marks on the swingarm, measure from the centre of the wheel spindle to the edge of the swingarm where the drive chain puller plate interfaces with the swingarm. They're also very sensitive to sprocket/wheel alignment, I'd also check the front sprocket lay shaft bearing and the rear wheel hub bearing and possibly the rear wheel bearings.
If you still can't get it correct check the swingarm bearings.
