Hello I am having my once registered but not any more (6months lapse) rs 250 converted into an rs 500 by the great guys at the two stroke shop. My question is how hard is this thing going to be to get registered in NSW? What do I need to get this on the road? Does it really need an engineers certificate? All the bike is stock bar the cradle, engine and pipes, nothing totally custom except the pipes are hand made, rest is bought, no chops or suspension changes.
