Brad, it really doesn't matter whether the sprocket is inboard or outboard of the frame, so long as the chain clears the frame by 3/8" or so. When it begins to "walk around" from cornering, chain flex, Etc., you don't want it to be able to touch the frame. A lot of us like our engines centered in the rear end. We just think it makes for better ba1ance and handling. As you can see from the pic, the n1ke is centered. When the chain is adjusted, you don't want to be able to move it fore and aft more than about 3/4"-1", measured at half the distance from where it comes off the clutch sprocket, to where it engages the axle sprocket. Modern space chain is pretty "loosie-goosie", and it can move from side to side a bit under cornering stress. TJ
