Thank you in advance for any help!
A kid came into my shop with a basket case YZ250, who needed a spare engine that I had lying around for an old Honda.
I really wanted to help him out because the Honda engine had just been sitting, so I accepted his offer for a trade. I paid no mind to the old 99, and he sat it aside in the corner of our shop.
The bike was/ is in a million pieces, and after a few days I started rummaging through the boxes of parts that accompanied the bike.
When I located the cylinder I noticed it had some Engravings from March of 1999. I will attach a photo of the Engravings, which are what I am seeking help with.
Wondering if anyone can decode this cylinder for me? I called Pro Circuit first and whomever typically handles this sort of thing was not in today so I figured it would be fun to throw up on Vital.
Thank you guys, I hope you all had a great Monday!

The Shop
DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Luxon 4-Post Bar Mounts
$189.95 - $239.95
That would be something. I'd basically have no choice but to proceed with that project!
Can't wait to hear back from PC. Sent am email.
Good job thinking outside of the box however
Just a guess.
Not sure what the SPL would mean...
Would be kinda neat if that was off the bike from March of 99 when he won Daytona that year.
He won every SX in March that year.
Sounds like I was right.
But if PC confirms that I have something genuine, I will build this replica.
No doubt Jeremy was everything to me as a 90's kid at the races.
Sort of excited to do this now, especially with a YZ platform.

JMG was a cylinder porter for PC for years, if you have come this far, you probably starting to feel that pain in your mouth from bitting the bait! lol

That's hilarious about the bait! I honestly have not gotten too excited as the rest of the bike really does not stand out at all in terms of "factory" or really anything special. Very standard, but clean for it's age, 1999 YZ250.
I'd love to know more if you've got any other info past what you've already expressed?
Thank you all for chiming in!
So I guess I have some more homework to do. They could literally be nothing or perhaps it is what some of you above have mentioned.
You have your answer above.
Now, build it, brother.
Is there anything else special about any of the other millions of parts you see for this bike that look hand made or billet cnc?
There's literally nothing else about this bike that stands out about it. It's very clean for its age but also very stock and nothing special going on.
I will def. build this bike if I can find out more about the cylinder.
Thanks again to all who've donated time to this thread!
