I picked up a Bomber a bit ago for a steal, looks to be complete and original with the exception of the exhaust thought the bike came with one original. My plans are unclear, but I'm thinking I may just get it running and ride it as it looks; rough and rugged. I'm wondering what the deal is with engine numbers, and how far they typically stray from frame numbers, also, what is considered to be an exceptionally low production number? My engine # is 1005001, and the frame is 1007###. Does it seem like these may not be original to each other?
