I recently bought a 125cc quad as a repair project and as always theres more too it than what the seller has said. I am finding it difficult to source parts for it. Particularly the wheels! They are 3 stud 16x8-7 and cant seem to find them anywhere except Australia or Aliexpress for hefty postage prices. I've thought about just converting the rear to 4 stud hubs as the wheels are easier to get. Has anyone any insight on this or where I could get any parts?

Thanks in advance!
