I'm in the middle of a teardown and rebuild of my 87r. I already have the Sport LSR +2/+1 Arms ordered and paid for. I noticed when I took the axle apart that there are 15mm spacers that could conceivably be moved to the inside of the hubs, widening the rear by 30mm, or approximately an inch and 3/16. Is this an acceptable approach and stance/width for an "aggressive recreational" rider? The axle, amazingly, isn't rusted and shows almost zero runout when mounted on centers and indicated. Thanks for any input.
