Ever stop to think why would someone remove the serial number? I wouldn't have bought it.

n ° ME03E = 1903

That could be up to 92 to 01 in a 250. On those motors, the ID tag falls of sometimes because they are riveted on.

Good point, there’s definitely reasons other than theft for no serial number on Honda engines. I had to replace the left engine case on my 2000 CR125 back in the day and the new one did not have a serial number.

The dealer is supposed to stamp it when you buy it. I don't remember if they require the old case back.

You always have to be that guy. Every time you get the chance. Ever stop to think that maybe it doesn't have a serial for some other reason, genius?

maybe you could remove the flywheel cover and see if the flywheel has a part number. search it. i seem to remember different hpp engines had slightly heavier or lighter flywheels.

Tomorrow I'll remove the cover and I hope to find one code.

That's only the one that has the wooden spoke wheels.

Yes you can see where it goes, in front of the shift shaft below the countershaft.

Well it's a legit question to ask especially when buying just an engine from some random guy you don't even know don't you think? Could be stolen or could be any other reason, still need an explanation.

If the seller can't explain why it's not on it, don't buy it. It's pretty easy to tell if someone is telling the truth or bullshitting. Last thing you want is to part with your money only to have the cops show up at your place to ask questions you can't answer and take it back to the original owner. There's shady people everywhere and you can't trust everyone.

I've bought the engine from a friend; the engine was in a go-kart and probably the plate whit engine serial number is went out last year in the engine's rebuild.

I will tell you that engine is one of the best 250 racing engines ever made In my opinion. reliable too. I raced a 92, a 93, a 95 and a 96 and I don't think i could tell the difference between any of those years on the motor. They all ripped and pulled so hard you needed to be in great shape just to hang onto one of those babies at speed.

I'm currently thinking about putting one of those in a 2007 cr 250 I have. Way better than the last generation cr engine in my mind.

If you want a real rocket....throw a pro circuit pipe on it and hang on.

if the carb in the pic is the original carb its not a 97 or 98 because it had powerjet carbs with wires.
also you could see what slide the carb has. people seldom change carb slides.

hopefully its a 95 to 96 engine those were badass. 1999 not so much from what i remember.

The 1999 was a good motor too. More bottom than the 1997 which was a screamer and not quite as good as the 95-96. I had Varner do a 94 cylinder recently. It was a little lazy on the bottom but ran hard. It rips better than the 96 we have. Great motors, still great bikes.

I had several of those as well. were the power valves identical all those years?

Looks like the 'J' cylinder stamp is a 98/99 cylinder...Is it a flat-top or dome piston? That would give you some insight as well. Great motor, whichever year it ends up being cool

The flywheel part number is : 032000-7931 .. is probably a 1994 engine?
