No and Yes.
The dominator sprockets have a bigger hole in them,
so the sprocket ends up much too close to the crankcase.
Singles have their own series of sprockets.
With suitable sprocket offsets.
Someone like Stu Rogers or Mike Pemberton in the UK should be able to supply something suitable.
Or buy a suitable sprocket blank, and bore a taper in the sprocket boss to suit.

I've got about 6 single row chain engine sprockets, the tapers have the same angle but slightly different diameters in every one of them. So the sprocket sits out at different distance from the crankcases. I still use a single row chain with the 850 commando engine, however I've made a carrier which fits the taper and carries floating Jawa speedway sprockets. Why would you want to mess around with that rubbish ?

The sprocket carrier cost $200 to have made. Jawa speedway sprockets are cheap and readily available in all sizes up to 25 teeth. To change them, only takes dropping the chain and undoing one nut - no pulling the sprocket off the taper. When I had the carrier made, the price included the puller which fits into a thread in the end. The sprocket floats, so it doesn't matter much where the clutch is.
