Hi, I'm looking to buy a Honda Phantom and have a couple of questions: A. Is there a quick and easy way to check the year of the bike from the engine and VIN numbers? e.g. Something like the 3rd and 4th digits of the engine number are the year made. A lot of the 2nd hand bike sellers here seem to take older 2nd hand bikes and combine together frames, engines, other parts from old worn out/broken bikes to make something that runs. B. Are there any common problems with the Phantom that I should look for when buying? Thanks.
