Hi, 
I am sure my tlr 200 is spose to have some sort of spacer on the front sproket shaft. 
As the chain has worn away a bit of the engine casing where it has been rubbing against it. 
The sproket i have on it at the moment is approx 6mm wide and there is about a 4-5mm gap of movement before it touches the circlip. 
Its not the shaft as this has a little play but not much. 
Even if it is not spose to have a spacer, does it have a wider sproket? 
i have attached a pic of the engine and sproket. 
Could someone please either see if there bike has a spacer or see if there sprocket is wider than 6mm 
I would be gratful if someone would do this for me. 
Many Thanks 
James
