centering rim

I just got a ZRX12 rear end. It seems that the rim is not centered in the swing arm.It is off by 3/16". Is this normal ?should this be a concern?

id check to see if swingarm is straight 1st,then i would make new spacers to center up wheel once its on your bike.swingarm might be offset in frame for clearance issues on bike it came off of

check to see if the center of the tire is under the center of your frame

I shimmed the wheel and did an alignment check(with string) with the front tire and it seams good now.I just cant understand why it would be offcenter?

It seams I will need a 1" offset sprocket on the front(this will require a suport), and I have clearance issuse with the frame.What do you think if i reduce the front offset by 3/8" and add it to the back sprocket in the oposite direction?this would give me 2 offset sprockets and eliminate the need for a front sprocket suport, while adding frame clearance.

makes sense to me as long as its straight

just remember offsetting the rear sprocket towards the tire can only go so far before it hits the tire;) make sure you have the room before you try anything. also, you probably wont find an offset rear sprocket. you could make one, but I think the easiest thing to do would be to machine down the sprocket carrier to move the stock sprocket in for the same effect;)

Ive decided to remove material from the rear hub (cush drive) to make it line up with the front sprocket.
