front end swap snag

I'm putting 900rr forks in erion racing triples and using the stock wheel. my problem is the stock wheel spacers are coming up 12 mm short. My calculations say I need a 21.6 mm left spacer and a 27.4 mm right spacer. other than the machine shop does anyone have any suggestions? would 900rr spacers fit? does anyone make and sell custom spacers cheap?

- You could try using "machine buschings - 7/8" from Tractor Supply. They are 2mm thick so you would need 6 of them - that will set you back $2. I have seem different thicknesses at Lowes and Home Depot as well if you need to better balance left and right clearances.

- For a more precise solution, McMaster-Carr sells all kinds of special spacers and shims in metric sizes as well as SAE - take a look here:

Your best option is to have a machine shop make spacers for you, but these are some cheap, temporary alternatives. JB

I would call ALL *****, when I spoke with them, they have all sorts of different bearings and spacers for wheels. They'll cross-reference for you to find what you need. It might be off a BMW or Kawi, but it would be what you need.

Good luck.

I had to fab up some spacers for wheels I put on. I asked here. consensus was very much to use a machine shop to be sure they are right, square and axle axis perfectly perpendicular to sides. It was very cheap to have them make them and the simplest solution in the end. I just took spacer I had and said recreate only make it this length etc. Just be sure to measure perfectly. twice.

I think I'm just gonna go to the machine shop so I can get exactly what I need in one piece without any cut corners.
