Long story short I'm in the process of buying an out of state titled Harley with a blown motor. The bike used to be titled in CA (year 2000). Currently titled Washington. My concern is with that damn engine number on the title. I want to put a non-emissions compliant S&S motor in it and I only want to deal with the DMV once. If they have no record of an engine number than they won't know the new S&S motor isn't the original. If they do, I'm not necessarily porked since I could tell them the motor swap happened in WA. Just in case, I'd like to know before sinking $8000 into this damn project. What I want to know is did CA use the engine number on motorcycles from the year 2000? I'll assume if you've got a 2005, could you please check your title to see? Thanks much inmates!
