No Engine Number Mystery - Plate is Blank

[londonboards]

Just wondered if anyone has seen one of these before?

The engine number plate does not look as if it's been filed off. The surface area is pitted.

Why doesn't it have a number?





It's on a recently acquired GS1150 / GSX1100 lump.

Check just below the Top Rear motor mount...

You just need some letter and number stamps....!
(God help the "Chicagoan" left in me...)

Cases bought new from a Suzuki dealer are not stamped. Just blank.

Replacement cases - thrown chain wrecked the originals, likely. Mucho moolah in the day.

I can see a hint of the old #'s they have been eaten away with acid you got a stolen motor.
What do you do now?

Never heard of anyone using acid to get rid of numbers...

The only hint of previous stamping I can see is what looks like a "figure eight" shape, but it's definitely not an "8" from previous numbers. The proportions are way off, and the position isn't right.

I just looked at the three spare 1st gen 750/550 engines that I have in the shop, and all of them have a smooth machined looking surface on the boss where the numbers are stamped. I'm not sure if the tscc engines had a typical rough cast finish to them there as in your photo, or if it was acid etched. The warranty engine/engine cases was the only thing that came to my mind when I saw the title of your post, however.

The surface does not look right to me either. Never saw any with so many holes. Acid can make holes like that... especially on die-cast or magnesium. I know from being the chrome plater's wife.
Also, I do not see the oval ridge around the numbers being raised and even. Looks suspicious to me. (I'd have someone re-tap the numbers and letters into that spot...)

We rebuilt an old Kaw 900 many years ago. There were no stamps on the brand new cases. Had to get a "homemade" title, which sent an inspector from the Dept. of Transportation to check out the bike.
Save yourself some trouble and do it yourself. (Or, have a buddy help you.)

As long as we're getting goofy, would anyone like to try to decipher my engine number? (Upside-down)

First a piston now the number plate - what next?

Right-side up...

That black engine paint covers up a multitude of sins.

My race bikes have cases like that.... no vin stamp. They were purchased from Suzuki as replacement cases just as Dar and BB said
