Just put the bottom end together on a ypvs engine. The sprocket can be moved back and forth to the value of 2 teeth before it engages with anything. Does that seem right??  |

That will be normal as there is play between the pins on one gear and the slots it locates to.
No play would stop the gear engaging

Dogs? What do you mean Rich. The pins and slots in the gears are called dog clutches as the gears themselves are always in mesh. |

Dogs? What do you mean Rich. Sorry I should have explained a bit more! Not all of the gears in the box are splined onto the gear shafts. Some gears are 'floating' and drive by engaging with the fixed gears using dogs (pins) and slots. As per Roofmonster and Steve's replies, there is some play to allow the dogs to engage properly. What you are feeling is the play between the dogs and slots. This pic will hopefully show it better (random Google pic, not an RD!):  |
