Need some help with a VIN #...

So here is the so called lost sheep...


image-3708518437.jpg

This bike was brought to me by one of my regular customers(we'll call him Dave) in hopes of retrieving the VIN off of it and having it run by the local PD(his son is a Rainier cop) and returning it to the rightful owner if it turns out to be hot....the bike is supposedly own by Dave's son in law that is stationed at fort Lewis and currently deployed in the Middle East

Now trust me this bike would not be in my shop if I in any way thought some wrong doing may be going on and it will not be leaving until I find out the truth to the history of the bike

I just got it today so I haven't been able to look it over much or try to salvage what's left of the numbers but so far I've found that it's somewhere between a 1993-1995 Suzuki RM125

So what I'm asking is if anyone knows a way of recovering the vin numbers? Or were they stamped anywhere else on the bike?

That's where someone scratched it off, it's pretty rusted there now but I might be able to buff it a little to see some numbers

don't the police have some sort of acid-etching stuff they can use to "raise" a filed off serial number? i think they mostly use it on guns but would be the same application on bike.

Lightly buff the area with the finest emery cloth you have to remove rust and paint, then using a bright halogen light set to illuminate the area from as low an angle as possible take several digital pictures of the area with the camera set to as high a resolution as possible. Import the pictures into MS Paint (believe it or not) and you can manipulate the image in several different ways such as color invert, color erase (right click and hold to implement), and paint areas to make the numbers more readable.

If they were deliberately obliterated the application of a semi dilute solution of muriatic acid (pool acid) will etch the area, being less effective where the metal was compressed by the stamping procedure, and will bring the numbers up. This is the method used by police departments on guns.

There is also a possibility that magnafluxing the cleaned area will show the numbers, though faintly.

Good luck.

Rob

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

What worked the best? Acid? Buffing?

Just some sand paper then some scotch brite(bear claw) until I got enough of the rust removed that I could make out the numbers, it wasn't ground completely off...not sure what they were trying to do when they scratched on it

...any way I got ur runnin good but the carb just pours fuel, think there's somethin up with the floats, it's got some kind of goofy plastic seat setup for the fuel needle, and the clutch doesn't want to disengage

I wonder what naval jelly would've done for that rust. Good to hear it wasn't from the spice market.
