Hi I'm new to this and wondered if you guys could help me. I bought an 04 crf 250 with a damaged engine so I put in an engine from an 08 but on further investigation I think it's an 05 engine. I have tried to get the bike going but it looks like the spark is weak. It just backfires and doesn't even try to start. I wondered if it was because it's using the 04 cdi. Is there a way I can get the right year of this engine from the engine i.d?

Honda says not but I don't believe them. Is there anyone that can help me
The I.d is Engine number is ME10E 2124818 thank you

ME10E21 should be a 2005 engine, think from an R model. Sure somebody else will jump in to confirm this.

Yes that's what I was thinking. I'm sure the 04 cdi would still work on an 05. If I can get a definate year I'll just buy that year cdi to rule that out. Thanks for your quick reply

Anyone else know anything about the engine code years?
Thanks

I recall most service manuals have the VIN number designations listed in the forward section. Stating what each letter and number in the VIN means. Jut a thought for you.

Just looked, unfortunately they don't. I don't understand why they can't make it easier to find the year of the Engine?
