The engine on my '78 doesn't have a CX500 prefix in its serial number. My parts engine does, so did the one on my bike come from another type of bike? It's like this: PCO1E 211xxxx

Assuming it runs, that's good news! The three "recall fix" dots aren't on the engine and I was thinking it needed the cam chain tensioner parts replaced! My parts engine has the three dots so it's easy to see what they look like. Thank you, Cobram!

So if I understand that list, my CX500 PC1E-2214842 the engine is made 1981 (registered -83!) - but it's not CX500C?! And the body...?





Edit: plate on the body says CX500-23...etc so this is made between 2/1981 and 1982

New information from Honda - my bike is made 20.12.1980 so it's a couple of years older than the first registration says (-83) - so the Haynes information isn't quite correct.

(Body number CX500-23XXXXX)



Edit: date was 2012, was supposed to be 1980...

Forget the year your bike was first registered! Some bikes left the dealers´ showrooms long after the year they were manufactured.



One of my CX-es (all four have frames CX 500 23...) is registered as an -82, The other three as -81 models. The registration office may call it what they like - to me they´re all -81. And I´m the guy who´s buying spares to them!



An -82 500 standard (rare but they exist) should have frame No like CX 500 24... I´ve seen (on two occasions) Honda mechs scratching their heads when having to look for ignition- and cam chain tensioner related parts for them. -82 have automatic cam chain adjuster and non-CDI ignition (at least in Europe).



Many of the frame- and engine No lists we see are assembled by Americans. They never saw CX 500 standard after 1979. That´s why their lists aren´t complete.

Engine Serial Number GL500

Where is the engine number on the GL500?
Got my learner's permit (got a 39/40 on my test), insurance full coverage State Farm, but didn't have the engine number for the title transfer.

Eating Banana Leaf wrapped Oxaxca Pork Tamales before I go home for the engine number.

First, assuming you are in the US, the DMV would be asking for the frame VIN, not the engine number. The VIN for the frame should be on the data plate which is on the left side of the steering head (the plate might be on a frame member elsewhere). The VIN should also be stamped into the steering head stock on the right side.
The engine SN is stamped into the base of the motor left side under the left head, under the GL500 badge.

Before getting to the computer, I found it under the oil filler.
I have the VIN#. They want the Engine number. (see quote from PDF below)
This is Minnesota. We do things differently. ;)
Now to go back before everyone gets out of work.

Hey! I found a summer mesh padded motorcycle jacket at St. Vincent's! Looks new. $25.00
See through with padded shoulders, elbows and forearms.
Fate is looking kindly on my these days. Like "It was meant to be!"

"If the vehicle is a motorcycle, the engine number
must be recorded on the face of the title at the time of
transfer."

Well, at least you found it, but that is still an oddity for them to track it that way.

What's wrong w an engine swap? :confused:
I suppose you could take a low mileage engine and put it in another bike and a high mileage one with a low miles odometer and pass it off as a low mileage bike. Would you pay the same for a bike with 1,000 miles on the motor as one with 100,000 miles? ;)

Who has the engine / frame serial range for the '83 GL bikes?

Minnesota requires both the frame Vin # and engine # as it was explained to me by a DMW official to help track possibly stollen engines from being placed in legally titled frames. Think custom bikes of the 70's. When stealing bikes to cut up for parts was a very profitable business.

The VIN# is on the title. The Supervisor training my clerk told me that the Engine serial # was recently accidently was put on the title by the State, and that it wasn't supposed to be on the title because it was a "Check" during registration.

Makes complete sense related to people stealing and chopping the bikes up.

Related theft: I am a block Neighborhood Watch Captain so I get all the crime reports. My neighbors, especially with 4x4s with under carriage space, have been getting their catalytic converters cut off and stolen. One neighbor found cut marks on the new converter they just replaced for a stolen one. Battery operated SawsAlls and angle grinders make this quick work.

I imagine some people would put in a bigger engine than the frame was registered as having to save on insurance, too.
A 650cc costs more than a 500cc to insure? Interesting!
Does a turbo cost more too?
